PTC Resettable Fuses

PTC Resettable Fuses, also known as Polymeric Positive Temperature Coefficient devices, are a type of overcurrent protection component. They are designed to protect electronic circuits by increasing their resistance when excessive current flows through them, thus limiting further current to a safe level. Unlike traditional fuses, which must be replaced after one-time use, PTC fuses can reset themselves once the overcurrent condition ceases and normal circuit conditions are restored. This makes them invaluable in applications where frequent fuse replacement would be impractical or costly.

These components are commonly utilized in various consumer electronics, automotive circuits, and battery packs, where they help prevent damage caused by overcurrents and short circuits. The main characteristics of PTC Resettable Fuses include their self-resetting capability, durability, and cost-effectiveness in protecting electronic components. Major manufacturers of PTC Resettable Fuses include companies like Littelfuse, Bourns, and TE Connectivity, among others.
