PTC加熱器組件
PTC加熱器具有恒溫發熱特性,其原理是PTC熱敏電阻加電后自熱升溫使阻值進入躍變區,PTC熱敏電阻表面溫度將保持恒定值,該溫度只與PTC熱敏電阻的居里溫度和外加電壓有關,而與環境溫度基本無關.PTC加熱器就是利用PTC熱敏電阻恒溫發熱特性設計的加熱器件。產品符合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.
