LEAO, DYE, Panasonic, SWC Limiter thermal fuse

The fuse materials used in LEAO, DYE, Panasonic, SWC thermal fuses include copper, aluminum, iron and other elements, and copper is one of the most widely used materials. Copper fuses can be quickly melted when the current is overloaded due to their excellent conductivity, solid texture, good oxidation resistance and high temperature resistance. Thus, electrical equipment is effectively protected and electrical safety is ensured.

The melt material used in LEAO, DYE, Panasonic, SWC thermal fuses plays a vital role in the performance of thermal fuses and is one of the core components of the entire device. According to the characteristics of the melt material, we can divide them into two categories: low melting point and high melting point. Low melting point materials represented by tin and lead are usually made into the thickest cross-sectional shape because of their easy melting and relatively large resistivity characteristics, so the amount of metal vapor generated during the melting process is relatively large. These specific properties make this type of material more suitable for thermal fuse structures with lower breaking capacity. On the other hand, high melting point materials, such as copper and silver, are more suitable for making smaller cross-sectional sizes because they are not easy to melt and have relatively low resistivity. In addition, relatively less metal vapor is generated during the melting process, so this type of material is more suitable for use in thermal fuse designs that require high breaking capacity.

Operating temperature range:
SF type is 73 ℃ ~ 240 ℃, SM type is 76 ℃ ~ 187 ℃. There are various products with a rated current of 0.5A to 15A. Safety certifications include: UL, CSA, VDE, BEBA, PSE, JET, CQC … certificates. Comply with EU ROHS environmental protection directive requirements. NEC temperature fuse has the function of detecting abnormal temperature and cutting off the circuit. It can detect abnormal temperature rises of household or industrial electrical products and quickly and timely cut off the circuit, which can prevent the fire from being unburned.
NEC thermal fuse is a component that provides very reliable protection in over-temperature conditions. It has small volume, large overcurrent, non-reset, stable performance, convenient installation, and has a range of humidity settings and carrying capacity to choose from to meet customer application requirements.
