describe
From a safety and reliability perspective, PTC heaters are generally safer than traditional heating wires, offering higher isolation and withstand voltage, smaller footprint, and more stable performance. In some applications, traditional heating wires cannot pass safety certification, while PTC heaters can. Therefore, PTCs can be used in applications requiring high safety standards. However, not all PTC heating element manufacturers and components meet safety requirements, making it crucial to select a high-quality PTC heating element supplier. The main safety and reliability issues with PTCs used for solid-state heating include: first, the PTC ceramic body can break down and burn, causing a short circuit and burning the insulation layer; second, insulation breakdown and leakage can cause the outer casing to become electrically charged.
feature
PTC heaters are used to heat solids at a constant temperature. Their applicable heating temperature range is 0 to 300°C, with an ambient heating temperature range of 50 to 300°C and an ambient temperature range of -40 to 250°C. PTCs with surface temperatures that are too high or too low are difficult to manufacture and may not even function properly.
