We stock a range of PCB mount thermal fuses in both axial and radial lead types. When the rated functioning temperature of the thermal cutoff is exceeded, the device will fail open in the electrical circuit, breaking the flow of current. The allowable maximum voltage which can be applied to the thermal fuse. Theyre designed to fail under two conditions: Extreme heat (beyond their rating) and excess current (beyond their rating). Soldering them without super good heatsinking will blow them out. The allowable maximum current which the thermal fuse is able to carry. Fusible links (thermal fuses) are replaceable. The highest temperature of the thermal fuse at which it does not function or the functioning temperature does not become higher remarkably after being exposed for a certain amount of time. A thermal fuse is a cutoff which uses a one-time fusible link. They usually consist of a fusible alloy, flux. These thermal fuses are based on melting wire design whereas technical data is given in the tables on the right page. The highest temperature of the thermal fuse at which continuity does not occur for 10 minutes after the function of the thermal fuse. Thermal fuses or also temperature fuses are used for safe and one-time disconnection (isolation) of circuits. Explore our inventory to find a thermal fuse thats right for you. The highest temperature of the thermal fuse at which it does not open the circuit while passing rated current for 168 hours. Selco offers a wide variety of thermal fuses. Tolerance for METI is ☗ C except some types. Tolerance of rated functioning temperature is +0, -10 C for IEC 60691. Rating of the functioning temperature based on safety standards. The functioning temperature is not the Rated Functioning Temperature. The temperature at which the thermal fuse opens (fuses off) while passing 0.1 amp or less in a controlled oil bath at arise of 1 C per minute. They are miniature, NON-RESETTABLE temperature sensitive. Opening Temperature / Cut-off Temperature Description: Thermal Cut-Offs (also known as Thermal Fuses) are now included in the NTE product line. The following definitions apply to our range of Elcut thermal fuses:
