Specification
LP-ISM series
Product Description
LP-MSM is a resettable fuse, which is used in a variety of micro-devices. The fuse adopts organic polymer and conductive particles materials to be made through a special technology. It is a new type of surface mount fuse. It is a fast-acting fuse and can be resettable. In electrical properties, the fuse can also play the role of ordinary fuse for over-current protection. Therefore, to a large extent, it replaced the ordinary fuse. The fuse is recommended to be installed by welding manually or wave soldering in pin-type PTC. The resettable times of the fuse can reach more than one thousand times.
Features
