SURGE-GARD ICL Inrush Current Limiter Circuit Protection Devices SG130 NTC Thermistors 2.5 Ohms ±20% 8A MF73T-1 2.5/8

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.

Specification

Features
