Fuses
Fuses, eFuses, thermistors, and fusible resistors — which and when?
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 […]
