Now with Extended Resistance Range to 10,000 Megohms and Additional Models
Temperature Coefficient as tight as 80 ppm/°C, Combined with Excellent Long-Term Stability and Precision Tolerances.
Caddock's Micronox® resistance films are the source of
the Type MG Precision High Voltage Resistors' outstanding
combination of performance features:
Single-resistor values as high as 10,000 Megohms.
Maximum continuous operating voltages as high as
48,000 volts ("-15" ratings).
Overvoltage capabilities of 150% of standard working
voltages for all models and values, (except "-15" ratings).
Resistance Tolerances from ±1.0% to ±0.1%.
Temperature Coefficient, for standard resistance range, of
80 ppm/°C in combination with resistance tolerances as
tight as ±0.1%.
Type MG resistors have demonstrated stability of 0.01%
per 1,000 hours in extended load life testing of standard
resistance range values.
This exceptional performance has been proven through
many years of use in equipment that demands the highest
reliability and stability, including TWT amplifiers, X-ray
systems, geophysical instruments, and medical electronics.
Preconditioning for Power and Voltage Ratings
All power ratings and maximum operating voltage ratings
are for continuous duty. These ratings are based on pre-
stress voltage levels applied during the manufacturing
process to provide for stable resistor performance even
under momentary overload conditions.
Maximum operating voltages 60% higher than the values
listed in the table may be specified by adding "-15" to the
model number (Example: MG750-15). Note that overload
and overvoltage ratings do not apply to the "-15" resistors.
Resistance ranges for "-15" resistors shown in the table are
from "-15 Min." to "Standard Max."
Non-Inductive Performance
Most models are manufactured with Caddock's
Non-Inductive Design which uses a serpentine resistive
pattern that provides for neighboring lines to carry current in
opposite directions, thereby achieving maximum cancellation
of flux fields over the entire length of the resistor. This
efficient non-inductive construction is accomplished without
derating of any performance advantages.
Insulation Resistance: 10,000 Megohms, min.
Overload/Overvoltage: 5 times rated power
with applied voltage not to exceed 1.5 times max-
imum continuous operating voltage for 5 seconds
.

Now with Extended Resistance Range to 10,000 Megohms and Additional Models
Temperature Coefficient as tight as 80 ppm/°C, Combined with Excellent Long-Term Stability and Precision Tolerances.
Caddock's Micronox® resistance films are the source of
the Type MG Precision High Voltage Resistors' outstanding
combination of performance features:
Single-resistor values as high as 10,000 Megohms.
Maximum continuous operating voltages as high as
48,000 volts ("-15" ratings).
Overvoltage capabilities of 150% of standard working
voltages for all models and values, (except "-15" ratings).
Resistance Tolerances from ±1.0% to ±0.1%.
Temperature Coefficient, for standard resistance range, of
80 ppm/°C in combination with resistance tolerances as
tight as ±0.1%.
Type MG resistors have demonstrated stability of 0.01%
per 1,000 hours in extended load life testing of standard
resistance range values.
This exceptional performance has been proven through
many years of use in equipment that demands the highest
reliability and stability, including TWT amplifiers, X-ray
systems, geophysical instruments, and medical electronics.
Preconditioning for Power and Voltage Ratings
All power ratings and maximum operating voltage ratings
are for continuous duty. These ratings are based on pre-
stress voltage levels applied during the manufacturing
process to provide for stable resistor performance even
under momentary overload conditions.
Maximum operating voltages 60% higher than the values
listed in the table may be specified by adding "-15" to the
model number (Example: MG750-15). Note that overload
and overvoltage ratings do not apply to the "-15" resistors.
Resistance ranges for "-15" resistors shown in the table are
from "-15 Min." to "Standard Max."
Non-Inductive Performance
Most models are manufactured with Caddock's
Non-Inductive Design which uses a serpentine resistive
pattern that provides for neighboring lines to carry current in
opposite directions, thereby achieving maximum cancellation
of flux fields over the entire length of the resistor. This
efficient non-inductive construction is accomplished without
derating of any performance advantages.

Now with Extended Resistance Range to 10,000 Megohms and Additional Models
Temperature Coefficient as tight as 80 ppm/°C, Combined with Excellent Long-Term Stability and Precision Tolerances.
Caddock's Micronox® resistance films are the source of
the Type MG Precision High Voltage Resistors' outstanding
combination of performance features:
Single-resistor values as high as 10,000 Megohms.
Maximum continuous operating voltages as high as
48,000 volts ("-15" ratings).
Overvoltage capabilities of 150% of standard working
voltages for all models and values, (except "-15" ratings).
Resistance Tolerances from ±1.0% to ±0.1%.
Temperature Coefficient, for standard resistance range, of
80 ppm/°C in combination with resistance tolerances as
tight as ±0.1%.
Type MG resistors have demonstrated stability of 0.01%
per 1,000 hours in extended load life testing of standard
resistance range values.
This exceptional performance has been proven through
many years of use in equipment that demands the highest
reliability and stability, including TWT amplifiers, X-ray
systems, geophysical instruments, and medical electronics.
Preconditioning for Power and Voltage Ratings
All power ratings and maximum operating voltage ratings
are for continuous duty. These ratings are based on pre-
stress voltage levels applied during the manufacturing
process to provide for stable resistor performance even
under momentary overload conditions.
Maximum operating voltages 60% higher than the values
listed in the table may be specified by adding "-15" to the
model number (Example: MG750-15). Note that overload
and overvoltage ratings do not apply to the "-15" resistors.
Resistance ranges for "-15" resistors shown in the table are
from "-15 Min." to "Standard Max."
Non-Inductive Performance
Most models are manufactured with Caddock's
Non-Inductive Design which uses a serpentine resistive
pattern that provides for neighboring lines to carry current in
opposite directions, thereby achieving maximum cancellation
of flux fields over the entire length of the resistor. This
efficient non-inductive construction is accomplished without
derating of any performance advantages.

Type CD Low Resistance Precision Chip Resistors
Style FC - Flip Chip Version is a surface mount version with solderable pedestal terminals for flip chip soldering.
Note 1: General Applications - The power rating for
general applications is based upon 0.5 sq. in. (300
mm2) of termination pad or trace area (2 oz. copper)
connected to each end of the resistor. Maximum chip
temperature is 150°C. Use Derating Curve to derate
appropriately for the maximum ambient temperature
and for the temperature limitations of the adjacent
materials.
Note 2: Thermal Resistance - In High Power Applications where the circuit board material
provides high heat sinking benefits (such as IMS, Alumina, or other) the thermal resistance of
the chip resistor is useful to establish the maximum power capability of the chip resistor in the
application. The film temperature is measured at the center of the resistor element and solder
pad temperature at the center of the solderable pedestal (point X in the recommended circuit
layouts shown below). Maximum temperature of the chip resistor (at the center of chip)
should not exceed 150°C through the temperature range of the application
.

Now with Extended Resistance Range to 10,000 Megohms and Additional Models
Temperature Coefficient as tight as 80 ppm/°C, Combined with Excellent Long-Term Stability and Precision Tolerances.
Caddock's Micronox® resistance films are the source of
the Type MG Precision High Voltage Resistors' outstanding
combination of performance features:
Single-resistor values as high as 10,000 Megohms.
Maximum continuous operating voltages as high as
48,000 volts ("-15" ratings).
Overvoltage capabilities of 150% of standard working
voltages for all models and values, (except "-15" ratings).
Resistance Tolerances from ±1.0% to ±0.1%.
Temperature Coefficient, for standard resistance range, of
80 ppm/°C in combination with resistance tolerances as
tight as ±0.1%.
Type MG resistors have demonstrated stability of 0.01%
per 1,000 hours in extended load life testing of standard
resistance range values.
This exceptional performance has been proven through
many years of use in equipment that demands the highest
reliability and stability, including TWT amplifiers, X-ray
systems, geophysical instruments, and medical electronics.
Preconditioning for Power and Voltage Ratings
All power ratings and maximum operating voltage ratings
are for continuous duty. These ratings are based on pre-
stress voltage levels applied during the manufacturing
process to provide for stable resistor performance even
under momentary overload conditions.
Maximum operating voltages 60% higher than the values
listed in the table may be specified by adding "-15" to the
model number (Example: MG750-15). Note that overload
and overvoltage ratings do not apply to the "-15" resistors.
Resistance ranges for "-15" resistors shown in the table are
from "-15 Min." to "Standard Max."
Non-Inductive Performance
Most models are manufactured with Caddock's
Non-Inductive Design which uses a serpentine resistive
pattern that provides for neighboring lines to carry current in
opposite directions, thereby achieving maximum cancellation
of flux fields over the entire length of the resistor. This
efficient non-inductive construction is accomplished without
derating of any performance advantages.
Insulation Resistance: 10,000 Megohms, min.
Overload/Overvoltage: 5 times rated power
with applied voltage not to exceed 1.5 times max-
imum continuous operating voltage for 5 seconds

Type CD Low Resistance Precision Chip Resistors
Style FC - Flip Chip Version is a surface mount version with solderable pedestal terminals for flip chip soldering.
Note 1: General Applications - The power rating for
general applications is based upon 0.5 sq. in. (300
mm2) of termination pad or trace area (2 oz. copper)
connected to each end of the resistor. Maximum chip
temperature is 150°C. Use Derating Curve to derate
appropriately for the maximum ambient temperature
and for the temperature limitations of the adjacent
materials.
Note 2: Thermal Resistance - In High Power Applications where the circuit board material
provides high heat sinking benefits (such as IMS, Alumina, or other) the thermal resistance of
the chip resistor is useful to establish the maximum power capability of the chip resistor in the
application. The film temperature is measured at the center of the resistor element and solder
pad temperature at the center of the solderable pedestal (point X in the recommended circuit
layouts shown below). Maximum temperature of the chip resistor (at the center of chip)
should not exceed 150°C through the temperature range of the application
.

• Pedestal terminals in this design provide an ultra low resistance
connection pad which maintains the precision 0.010Ω ±1% at the
point of customer Kelvin connection to the resistor chip. The pedestal
terminal with its copper core also provides heat spreading which
enhances the high power handling capability.
• Thermal resistance is provided to optimize high power designs when
utilizing higher thermal conductivity circuit board substrates such as IMS or Alumina.
• High pulse handling and overload capability.
• Low inductance provides excellent high frequency and pulse response.
