Funzioni e applicazioni di fusibili elettronici (sperone)

Electronic fuses (sperone) are solid-state devices that protect electronic circuits from overcurrent conditions. Unlike traditional fuses, they can be electronically reset, offering a more convenient and efficient solution for circuit protection. eFuses protect against short circuits, overloads, and other fault conditions, preventing damage to devices and wiring.

Funzioni e applicazioni di fusibili di chip resettabili

Resettable chip fuses, also known as PTC (Coefficiente di temperatura positivo) 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.

The fuse element is the part that melts due to excessive current flow in the circuit. The fuse element is made up of materials that have a low melting point and low ohmic losses like tin, lead, and zinc. Filling powder fills the internal space of the fuse body.

Protezione eccessiva | 5×20 6×30 mm Cartridge Fuses

An overcurrent protection electrical fuse is a safety device that interrupts the flow of electricity in a circuit when the current exceeds a predetermined level. It acts as a sacrificial link, melting and breaking the circuit to prevent damage to wiring and other components from overheating or potential fires due to excessive current.

Surface Monte SMD CHIP CHIP FUSE FUSI Cina Fornitore

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, principio di funzionamento, and application:
