BOURNS SMD Thermal Cut-Off Fuse, 12A, 28V, 85°C

The BOURNS SMD Thermal Cut-Off Fuse is a high-precision, miniature thermal cutoff device designed to provide critical overtemperature and overcurrent protection. Engineered for demanding electronic applications, it acts as a vital safety component by responding virtually instantaneously to abnormal or excessive currents, thereby preventing potential damage or hazardous conditions.

This surface-mount device is particularly suited for safeguarding sensitive power sources such as lithium polymer and prismatic cells. Its fast-acting mechanism ensures reliable circuit interruption when predefined temperature or current thresholds are exceeded, offering an essential layer of protection in compact, modern electronics. The fuse will automatically reset once the ambient temperature cools to a safe minimum of 40°C, restoring functionality without manual intervention.

Part of the trusted Komatsulite SA product range, this fuse combines robust performance with a compact form factor ideal for space-constrained PCB designs. Its SMD (Surface Mount Device) terminals facilitate efficient automated assembly processes, making it a preferred choice for high-volume manufacturing. The precise 85°C functioning temperature and 12A current rating at 28V DC make it a dependable choice for a wide array of low-voltage, high-reliability circuits.
