PTC Thermistors,
Mini Chips for Over-Temperature Protection
Note
(1) Max operating temperature range is Tn +15 °C, indicated value
is for Tn = 150 °C.
FEATURES
• Well-defined protection temperature levels
• Fast reaction time (< 6 s in still air)
• Accurate resistance for ease of circuit design
• Excellent long term behavior (< 1 °C or 5 % after
1000 h at Tn +15 °C)
• Wide range of protection temperatures
(70 °C to 170 °C)
• Small size and rugged
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
Over-temperature protection and control in:
• Industrial electronics
• Power supplies
• Motor protection
DESCRIPTION
These
directly
heated
thermistors
have
a
positive
temperature coefficient and are primarily intended for
sensing.
MOUNTING
For clamping, reflow or hand soldering. Not intended for
ultrasonic soldering or for spot welding or bonding. All
standard solder alloys with low activated halogen-free
fluxes are acceptable.
PACKAGING
PTC thermistor chips are vacuum packed in 5000 pieces.
