JK SMD 1206 Resettable PTC Poly Fuse Surface Mount Overcurrent Protection
The JK SMD 1206 PTC Resettable Poly Fuse is a surface-mount overcurrent protection device that increases in resistance when excessive current flows, limiting the current and protecting sensitive electronic circuits. Once the fault is removed and the device cools, it automatically resets to its low-resistance state, eliminating the need for fuse replacement. Its compact 1206 (3216 metric) package is ideal for space-constrained PCB designs.
