Fast Response Insulated Radial Leaded Thin Film NTC Thermistor 100K 3950 50mm 75mm
Description Of The NTC Thermistor 100K 3950
MF55 series is a thin film type thermistor, NTC one chip is soldered on a thin lead frame, and then encapsulated with insulating polymer film. The maximum thickness is only 0.6mm (usually 0.5mm). Thin-film thermistors can measure surface temperature more efficiently, or can be installed within a tiny gap.
Typical Application Of The NTC Thermistor 100K 3950
· Copies, printers, office appliances, inverter fans, mobile power
supplies.
· Fire alarm system, grain depot storage system, aluminum electric
control panel.
· Battery protection board
. Car circuits, car brake systems, flow meters and other occasions
where the space is small and the temperature is high, or the
response time is short.
· Thermometer, lithium battery temperature protection.
Main Features Of The NTC Thermistor 100K 3950
* Excellent surface temperature measurement
* Very small thermal time constant
* Small size, fast response, high test accuracy
* Good interchangeability and consistency
* Operating temperature: -40～125℃
* Standard R25 values are 5kohms,10kohms,50kohms and 100kohms with
lengths of 11mm.15mm,20mm,25mm, 36mm,44mm.45mm,50mm, and 75mm .

Notes:
1). Do not bend the resistance wire frame at will to avoid the chip and wire frame falling off and causing poor resistance;
2). The temperature should not exceed 300℃ during welding, and the welding time should not exceed 0.5 seconds;
3). Use a hot air gun when shrinking the sleeve, and the temperature of the air gun should be controlled at about 120℃;
4). Use a constant-temperature soldering iron when soldering, with a flat soldering iron tip, holding the resistor in one hand and the wire in the other for butt welding, which can improve production efficiency and shorten welding time;
5). Special Note: Do not touch the chip (ie the top of the resistor) with your hands!
6). Custom made is available
