* 概述： |
| 用于各种荧光灯电子镇流器、电子节能灯中。不必改动线路将产品直接跨接在灯管的谐振电容两端，可以改变电子镇流器、电子节能灯的硬启动为预热启动，灯丝的预热时间达0.4-2秒，可延长灯管寿命三倍以上。 |
| * 原理： |
| 应用PTC热敏电阻器实现预热启动如图所示，刚接通开关时，Rt处于常温态，其阻值远远低于C2阻值，电流通过C1、Rt形成回路预热灯丝。约0.4-2秒后，Rt焦耳热温度超过居里点Tc跃入高阻态，其阻值远远高于C2阻值。电流通过C1、C2形成回路导致L谐振，产生高压点亮灯管。 |
| * 特点： |
| 利用PTC材料制做而成，产品体积小，耐电压高，寿命长，正常工作时功率消耗小。 |
