Product Description
SURGE-GARD ICL Inrush Current Limiter Circuit Protection Devices NTC Thermistors 2.5 Ohms ±20% 8A MF73T-1 2.5/8
Description
Negative Temperature Coefficient (NTC) thermistors are thermally sensitivesemiconductor resistors which exhibit a decrease in resistance as absolutetemperature increases. Change in the resistance of the NTC thermistor can bebrought about either by a change in the ambient temperature or internally by selfheating resulting from current flowing through the device. Most of the practicalapplications of NTC thermistors are based on these material characteristics.
