      Product Description:

贴片电容,又称多层贴片陶瓷电容, 按不同用材质和精度可分为NPO、X7R、X5R、Y5V四个系列,


1. NPO系列

采用一级瓷,通常使用AgPd做内电极,TC不随温度改变而改变,属温度补偿型产品,精度通常为±5%,更小容值的可低至±0.25PF、±0.1PF。这种产品因具有低损耗、电容浮动补偿、高稳定性等特点而通常被应用于振荡器、滤波器等产品中。


2. X7R、X5R、Y5V系列

采用二级瓷,使用Ni做内电极,精度依次为±10%、±10%(或±20%)、-20%~+80%。与NPO材质相比,这三个系列的产品损耗较高,容值随温度变化较大,在电路中主要起到耦合和退耦作用。
