Fuses, eFuses, thermistors, and fusible resistors – which and when?
Fuses, eFuses, various types of thermistors, and fusible resistors can be used to provide varying levels of circuit protection. Fuses provide 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 […]

Fusible resistors vs fuses
Safety standards often dictate what component provides the best protection against overcurrents. Todd Phillips, Saad Lambaz • Littelfuse, Inc. Most people would probably agree that the time it takes to recharge their cell phone, gaming console, or tablet computer is both inconvenient and annoying. Faster charging requires a more powerful charger or power supply. The […]
