.The JK-SMD0805-005 with PTC Resettable Fuses 0805 RoHS are surface mount, resettable fuses manufactured by Jinrui Electronic Materials . These devices are designed to protect circuits from an overcurrent or overvoltage condition, and act as an automatic circuit breaker when needed. When an overcurrent or overvoltage condition is detected, the fuse will heat up and blow, thus disconnecting the circuit from the power source. The fuse will then be in a “blown” state until it is reset manually. The RoHS compliant devices are packaged in a 0805 footprint and feature an integrated overvoltage protection capability, making them ideal for general purpose and high-end applications.
