BOURNS CB Series Thermal Cut Off Fuse 25A 28V DC 77°C

The BOURNS CB Series Thermal Cut Off Fuse is a miniature thermal cutoff device (TCO) designed to provide reliable overtemperature and overcurrent protection. Specifically engineered for lithium polymer and prismatic cells, this fuse controls abnormal, excessive current virtually instantaneously up to rated limits, ensuring the safety and longevity of your electronic components.

Operating with a functioning temperature of 77°C, the device effectively interrupts the circuit when dangerous heat levels are detected. It features a holding temperature of 40°C and a minimum reset temperature of 40°C, allowing for stable operation under normal conditions. Rated at 25A at 28V DC, it is a robust choice for demanding applications.

Equipped with blade fuse terminals and supplied without terminal protection, this TCO offers straightforward integration into your circuits. Its compact dimensions, measuring 43 mm in height, 33 mm in width, and 15 mm in depth, combined with a lightweight profile of just 0.355 grams, make it highly suitable for space-constrained installations where both performance and physical footprint are critical considerations.
