TSL250-080F-B-0.5-2

Ptc Resettable Fuses Overview

The Littelfuse TSL250-080F-B-0.5-2 is a surface-mount thermal switch designed for overtemperature protection in electronic circuits. This specific variant features a fixed operating temperature of 80°C and a reset temperature of 70°C, providing a 10°C hysteresis window to prevent rapid cycling. The device utilizes a bimetallic element mechanism that physically opens the circuit when ambient temperatures exceed the rated threshold. It is housed in a compact SMD package suitable for automated assembly processes on printed circuit boards.
