常见的一类电容陶瓷材质有:NPO、C0G, UJ, SL, N4700等,该类陶瓷电容温度系数的变化是确定的,容量和温度存在一个线性关系。频率特性和电压特性也非常好,但因介电常数不高,所以容量做不大。
常见的二类电容陶瓷材质有:Y5R,Y5P,Y5T,Y5S,Y5U,Y5V等,二类陶瓷材质其温度是非线性的,容量可以很大,但频率和温度却不恒定。
安讯高压陶瓷电容可根据客户要求定制,采取内部并联或者串联的设计做到高电压,大容量,高工作频率,高耐受冲击电压,超低局放等要求,可满足客户的不同需求。
安讯螺母电极端子系列的圆柱形超高压陶瓷电容已经广泛应用于送电、配电系统的电力设备和处理脉冲能量的设备中,如:功率补偿、限流、滤波、计量、储能以及分电压等产品中。电力系统的特殊性:交流、高电压、高频、处于室外环境 (-40°C到+60°C)、雷击、大电流等等,在恶劣环境,要求电容具有超强的稳定性,即变化率要小;同时,计量,分电压等,产品要求高精密度,这对处于这种环境下的高压陶瓷电容器的局部放电量有着极为苛刻的要求。安讯高压陶瓷电容具有优良的充放电性能,耐压高,频率特性好,能承受高冲击电压,超低局放等特点,有交流和直流应用供客户选择。
