Product Description
This type of thermal fuse is a non-resettable thermal protection device with ceramic casing, which is sensitive to the ambient temperature, accurate and stable operating temperature, small size and sealed structure.
Features:
- It is a non-resettable thermal fuse, which uses a fusible alloy as a thermal element.
- It is the smallest thermal fuse in the world. 1.4mm diameter.
- It is free of lead (Pb) and cadmium (Cd) and is RoHS and REACH compliant
- Very simple structure to ensure reliability and sealing of the heat-sensitive element reduces deterioration with age.
- It has excellent thermal properties.
- It uses an insulated container.

Working Principle
When ambient temperature rises to its operating temperature, the fusible alloy will melt and shrink into bulb on both sides of pin, with the help of surface tension and special resin, cut off the circuit permanently.
