Fuses, eFuses, thermistors, and fusible resistors — which and when?

August 25, 2021 By Jeff Shepard

Fuses, eFuses, various types of thermistors, and fusible resistors can provide varying levels of circuit protection. Fuses offer only the most basic level of overcurrent and short-circuit protection. Thermistors can be added to provide inrush current control, and a fusible resistor can provide both inrush current control and overcurrent/short-circuit protection. The most comprehensive protection is […]
