About this document

NTC Thermistors for Inrush Current Limiting by Ernesto Moya-Albor is a document available to read on EtoBox.

NTC thermistors can be used as inrush current limiters in switching power supplies. They limit surge current by functioning as a resistor that drops from a high cold resistance to a low hot resistance when heated by current flowing through it. The document provides details on selecting an appropriate thermistor based on factors like maximum permissible surge current, size of filter capacitors, maximum ambient temperature, and expected life of the power supply. It also discusses calculating thermistor resist
