NTC Thermistor for Cordless Drill Protection Board.infrared sensor lens Manufacturing

　　The initial resistance value of the NTC resistance value is large, but when the temperature increases and exceeds the threshold temperature, the resistance value of the thermistor decreases rapidly, and slowly returns to the initial resistance value after the power is turned off.

　　At the moment when the circuit power is turned on, a much larger transient surge current will be generated in the circuit than during normal operation, which will cause great damage to the devices in the circuit. Therefore, it is necessary to connect an NTC thermistor in series in the circuit to play The role of the protection circuit.

　　The NTC thermistor produced by Minchuang Electronics is suitable for the protection board of the rechargeable drill.

　　MF52 Beaded Small Black Head NTC Thermistor

　　Bead-shaped high-precision MF52NTC series thermistor for temperature measurement, bead-shaped NTC thermistor with epoxy coating. Smaller product sizes are enabled by new materials and manufacturing methods that offer the advantage of accurate tolerances and fast response times. MF52 thermistors are available in 5 lead types in standard or custom lengths.

　　The most important thing about the chip type thermistor is small size and no lead, which is very suitable for surface mount production.
