PTC加热器组件
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.
