BOURNS Thermal Cut Off Fuse, 28V, 72 Degrees C - 12A
BOURNS thermal cut-off fuse for lithium battery protection. 25A, 28V, 72°C function, 40°C reset. High-current safety device.
The BOURNS Thermal Cut Off Fuse is a specialised miniature safety device engineered for robust overtemperature and overcurrent protection. Designed primarily for lithium polymer and prismatic battery cells, it provides a critical safety mechanism to prevent thermal runaway and potential fire hazards. This high-current type fuse acts as a failsafe, offering instantaneous control of abnormal or excessive current flow to safeguard sensitive electronic components.
Operating at a precise functioning temperature of 72°C, the fuse is calibrated to respond reliably to overheating events. Upon activation, it requires the temperature to cool to a minimum of 40°C before a manual reset can be performed. This ensures the system is safely stabilised before being brought back online. The use of blade terminals facilitates a secure and straightforward connection within the circuit, simplifying installation in a variety of compact applications.
Constructed to meet demanding specifications, this component is part of the Komatsulite HC product range, known for its reliability in protection circuits. It is an essential element for designers and engineers building power management systems, battery packs, chargers, and other electronic assemblies where managing heat and current is paramount for safety and longevity.
By integrating this thermal cut-off fuse, you add a vital layer of protection to your project, helping to ensure compliance with safety standards and providing peace of mind. Its miniature footprint allows it to be incorporated into space-constrained designs without compromising on protective performance.
