六、EMI 滤波器的构成
滤波电容
　　滤波器所用的电容一般为陶瓷电容。由于其物理结构，这种陶瓷电容又称为穿心式电容。
　　穿心式电容自电感较普通电容小得多，故而自谐振频率很高。同时，穿心式设计，也有效
地防止了高频信号从输入端直接耦合到输出端。这种低通高阻的组合，在 1GHz 频率范围内，
提供了极好的抑制效果。
　　最简单的穿心结构是由内外电极和陶瓷构成的一个（ C 型）或两个电容（ Pi 型）。
这种电容的容量可从 10pF ，工作电压可达 2000VDC 。管式穿心电容因为其同轴性，即使在
10GHz 频率，也不会产生明显的自谐振。
　　穿心电容的介质为陶瓷介质，而陶瓷电容的容量会随环境温度变化而变化，这种容量变化
会影响滤波器的滤波截止率。陶瓷电容的容量温度变化率是由陶瓷介质本身决定的。因此，
选择适当的陶瓷介质非常重要。常见陶瓷介质及其容量温度变化率如下
