SMD Thermal Cut Off Fuse, 12A, 28V, 82°C

The SMD Thermal Cut Off Fuse is a miniature thermal cutoff device (TCO) designed for surface mount applications. Rated at 12A at 28V DC, it provides reliable overtemperature and overcurrent protection for lithium polymer and prismatic cells. It controls abnormal, excessive current virtually instantaneously, making it an essential safety component for battery management systems.

This fuse is engineered to respond to over-temperature conditions, with a functioning temperature of 82°C and a minimum reset temperature of 40°C. Its surface mount design (SMD) ensures easy integration into automated assembly processes, saving space and improving manufacturing efficiency.

Constructed under the trusted Komatsulite SA product range by Bourns, this thermal cutoff device is ideal for protecting sensitive electronic circuits against thermal runaway and overcurrent faults. Its compact dimensions (43mm height, 33mm width, 15mm depth) and lightweight design (0.05g) make it suitable for modern compact electronics.

Whether used in battery packs, power tools, or portable electronic devices, this fuse offers dependable protection and peace of mind. With a holding temperature of 40°C, it ensures stable operation under normal conditions.
