JK250-110U with PTC Resettable Fuses Through Hole RoHS is a through-hole mounted, time-delay, PTC thermally-driven resettable fuse manufactured by Jinrui Electronic Materials. It is designed to operate as both a stand-alone over-current protector to safeguard equipment, and as part of a system incorporating other components. The JK250-110U is RoHS compliant and has a tripping range of 250mA to 1.1A, a voltage rating of 32Vdc, and a temperature rating of 70-125°C. It features a fast response time (typically 10-50 milliseconds), is non-explosive, and has a high-current capability. It is an ideal choice for over-current protection in applications where space is limited.
