Elektronische zekeringen (aansporing) zijn vaste apparaten die elektronische circuits beschermen tegen overstroomcondities. In tegenstelling tot traditionele zekeringen, Ze kunnen elektronisch worden gereset, het bieden van een handiger en efficiëntere oplossing voor circuitbescherming. Efuses beschermen tegen kortsluiting, overbelasting, en andere foutvoorwaarden, het voorkomen van schade aan apparaten en bedrading.

Resettable chip fuses, also known as PTC (Positieve temperatuurcoëfficiënt) resettable fuses or PPTC (Polymeric Positive Temperature Coefficient) devices, are circuit protection components that automatically reset after a fault condition is cleared. They protect against overcurrent and over-temperature situations, offering a self-resetting solution that enhances reliability and reduces downtime in various applications.

Chip fuses are miniaturized circuit protection components that use surface mount technology (SMT). They are mainly divided into two categories: one-time fuse type and self-recovery type. The following is a detailed introduction from the aspects of classification, werkingsprincipe, and application:
