Discrete Radial NTC Thermal Resistor Thermistor Assy 100 Kohm 3950 25mm For HVAC
Description Of The NTC Thermal Resistor
MF55 series thin film thermistors are frequently used for applications where limited space is concern. With typical thickness of 0.9mm max they are ideal choice for precise temperature measurement between flat surfaces where quick response time is critical. MF55 series thermistors are available with wide range of RT characteristics and typical measurement tolerance less than +/-0.3°C.

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
