PTC加热器具有恒温发热特性，其原理是PTC热敏电阻加电后自热升温使阻值进入跃变区，PTC热敏电阻表面温度将保持恒定值，该温度只与PTC热敏电阻的居里温度和外加电压有关，而与环境温度基本无关.PTC加热器就是利用PTC热敏电阻恒温发热特性设计的加热器件。产品符合ROBS指令要求。

    When electric is added to PTC thermistors，the R-value will goes to　transition area,the surface temperature of PTC thermistors will be keep at a certain temperature.This temperature is decided by the curie　temperature and the added voltage instead of the environmeat　temperature.ROHS certificated.

    1.自动恒温，不需要温控系统，安全可靠。
    2.电压使用范围宽，可在12V-380V问根据要求设计。
    3.设计方便，功率，外形都可以根据需要任意设计。

    1.Automatic heating without temperature control, safe and reliable.
