Feature
PTC heaters are used to heat solids at a constant temperature. The suitable heating temperature is 0~300°, the normal temperature heating temperature is 50~300°, and the applicable ambient temperature is -40~250°. PTCs with surface temperatures that are too high or too low are difficult to manufacture, and may even have no PTC characteristics.
Description
Considering safety and reliability, PTC heaters are generally safer, more resistant to isolation voltage, smaller and more stable than traditional heating wires. In some applications, traditional heating wires cannot pass safety certification, but PTC heaters can, so PTC can be used in situations with high safety requirements. However, not all PTC heating element manufacturers and all PTC heating elements meet safety requirements, so we must choose PTC heating element manufacturers with good quality to supply. When PTC is used for solid heating, the main safety and reliability issues are: first, the PTC ceramic body breaks down and burns, causing a short circuit and burning the insulation layer; second, the insulation layer breaks down and leaks electricity, making the shell charged.
