- >10,000MΩ/ μF(C>0.33uF) AT25℃
- ENDURANCE:
- THE TEST VOLTAGE 2,500VAC SHALL BE APPLIED FOR 1000HOURS IN THE85℃CHAMBER. DURING THIS PERIOD, 1000VAC 20KHZ FOR A PERIOD OF 0.1SEC BE APPLIED ONCE EACH HOUR. AFTER THE TEST. ΔC/C≦10%, ΔDF≦0.15%, ΔIR≧50% OF THE SPECIFIED VALUE.
- 采用METALLIZED POLYPROPYLENE材质
- DF值小,常使用于震荡电路(如补振电路),高频时需注意DF值变化
- 具有安全保护作用,在较大脉波冲击时,会造成OPEN的现象且不会爆裂、自燃等危险伤害;可保护其他组件或零件
- 一边使用于电源跨接处,可消除AC电源之交流声及防止大脉波之流入
