The content of this specification may change without notification 12/07/07
188 Technology Drive, Unit H, Irvine, CA 92618
0.1% tolerance resistors and resistance range from 240 ohm to 51K ohm are available as a semi-custom solution
Use of heat conduction grease on surface of flange is recommended.
Insulation material is unnecessary between flange and resistors; the flange and resistor are separated by alumina substrate.
It surface mount soldering, temperature profile in the flange shall not exceed 220°C.
Heat sink design will be performed when the resistor operating temperature is less than 155°C
Heat resistance between resistor and flange is 3.6K/W
For application to r-f circuit, Lead formed RHP-10X (smd) is prepared; RHP-10X are screw mount style.
At resistance from 220 to 51kohms rating power shall be restricted in 10W.
Heat resistance between resistor and flange is 5.9 C/W.
Heat resistance between resistor and flange is 3.3 C/W
At resistance from 220 to 51kohms rating power shall be restricted in 20W.
The terminal material is Tin plated copper, but inside of resistor contains PbAg high melting solder that is exempted by RoHS directive
At flange soldering, temperature profile in flange shall not exceed 270°C for 30 minutes.
Heat resistance between resistor and flange is 3.3C/W.
This model shall be fit to Copper of printed wiring board with lower temperature solder than 220°C. Sn-Cu soldering
will be done by soldering iron with 300°C -350°C tip temperature for less than 30 minutes.
Using heat conduction grease on surface of flange is recommended.
Heat resistance between resistor and flange is 1.3 K/W. Heat design will be done, as resistor temperature shall be under 155°C in operation.
Heat resistance between resistor and flange is 3.3 C/W.
5ppm TCR resistors are available as a semi-custom product
At resistance from 220 to 51kohms rating power shall be restricted in 30W.
Please note, terminal material is Tin plated copper, but inside of resistor contains PbAg high melting solder that is exempted by RoHS
Flat surface heat sink, thermal compound and sufficient mount screw torque will be necessary for good
In a rush current protection application, such as charge current limitation resistor, sufficient power
derating will be necessary.
