Description
The Bourns SC85AAB is a specialized Thermal Cutoff (TCO) fuse designed to provide reliable over-temperature protection for sensitive electronic assemblies. Rated for 25A with a precise 85°C cutoff temperature, this component acts as a critical safety barrier against thermal runaway and overheating in compact electronic devices.
Packaged for SMD (Surface Mount Device) assembly, the SC85AAB is engineered for modern, automated PCB manufacturing processes. Whether protecting battery management systems, power supplies, or specialized industrial controllers, this thermal fuse offers high-performance thermal sensing in a low-profile, surface-mount form factor.
Key Features
- Precision Thermal Protection: Engineered to permanently interrupt the circuit when the ambient temperature reaches 85°C, preventing fire hazards and component damage.
- SMD Efficiency: Optimized for surface-mount assembly, reducing production time and footprint requirements on the PCB.
- High Current Capacity: Capable of handling up to 25A, making it suitable for a variety of power-intensive electronics.
- Trusted Bourns Quality: Built to stringent industry standards to ensure consistent thermal activation and electrical safety.
Package Includes
- 1 x Bourns SC85AAB Thermal Cutoff (TCO) Fuse (25A, 85°C)
