Komatsulite is a pioneer in the development of mini-breaker technology. Designed to enable

long battery life, these valuable Thermal Cut Off devices are available with a high current

draw, and fast battery recharging cycle. Delivering a unique protection solution, mini-breakers

combine a bi-metal switch and a PTC to enhance the features of both, thus providing a superior

battery protection solution. The mini-breaker’s hybrid nature allows it to effectively protect

against overcurrent and overtemperature conditions simultaneously. Mini-breakers are known

for their stability, enhanced allowable voltage and improved leakage characteristics. The low

resistance and compact package make the Komatsulite™ mini-breaker an optimal alternative for

battery protection in countless applications.

Komatsulite continues to expand its product line with the goal of maintaining the highest

safety reliability based on quality ISO 9001, ISO 14001, and ISO 27001 certifications. Giving

developers additional confidence, Komatsulite has a proven track record of having received

no field returns with more than two billion devices shipped since 2007. As a Bourns company,

Komatsulite™ mini-breakers are supported by decades of circuit protection technology

expertise, superior customer service, and global distribution sales channel. For space-

constrained portable electronics, mini-breaker Thermal Cut Off devices offer a robust and

complete alternative for the protection of lithium cells in a compact, single package solution.
