BOURNS 25A 28V DC Thermal Cut Off Fuse, 72°C, SMD

The BOURNS Thermal Cut Off Fuse is a sophisticated miniature safety device designed for precise protection in sensitive electronic circuits. Rated at 25A and 28V DC, this Thermal Cut-Off (TCO) responds virtually instantaneously to control abnormal or excessive current, safeguarding your components from damage. It provides robust overtemperature and overcurrent protection, making it an ideal solution for securing lithium polymer and prismatic cells within battery packs.

Its compact SMD (Surface Mount Device) design allows for efficient integration onto printed circuit boards, saving valuable space. The fuse is engineered to function at a precise temperature of 72°C, at which point it will activate to interrupt the circuit. After activation, the device will automatically reset once the temperature falls below its minimum holding temperature of 40°C, ensuring ongoing protection cycles.

Constructed with reliability in mind, this TCO is a critical component for enhancing the safety and longevity of power supplies, battery management systems, and various DC applications. Its fast response time and accurate temperature thresholds provide peace of mind in preventing thermal runaway and electrical faults.
