Optifuse FSC-1.25A is a fuse, quick blow, 1.25A, 250VAC, glass, 5x20mm bulk manufactured by Optifuse. It is a fast-acting fuse designed for use in a variety of electrical and electronic applications. The FSC-1.25A glass fuse is designed to protect circuits from overloads, short circuits, and other electrical faults. The fuse features a glass body with a nickel alloy end caps for efficient heat diffusion. The improved heat dissipation capabilities of the nickel alloy allow high over-current protection under various fault conditions. The fuse has a quick-acting action which ensures a fast response and offers superior performance in comparison to other non-fused circuit protection methods. The low current limit allows the fuse to provide a high degree of over-current protection without sacrificing system performance. The FSC-1.25A fuse has a compact design which makes it ideal for use in tight spaces and can be used in many different applications including industrial automation, telecom, and automotive systems.
