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:
| EIA介质类别 | COG（NP0） | X7R | Z5U | Y5V |
| 超稳定 | 稳定 | 一般用途 |
| 工作温度范围 | -55℃~+125℃ | -55℃~+125℃ | -10℃~+85℃ | -30℃~+85℃ |
| 最大容量温度变化率 | 0±30ppm/℃ | ±15% | -22%~+56% | -22%~+82% |
| 绝缘电阻Ri | ≥104mΩ | Cr≤25nFRi≤4000MΩ Cr≤25nFRi*≤100S |
| 损耗（tanб） | Cr>50pF≤0.015 Cr≤50pF≤0.015 （15/Cr+0.7） | <0.025 | <0.030 | 0.050 |
| 介质强度 | 工作电压 200V 500V >1KV | 施加工作电压的倍数（加压时间5秒，充电电流50max） |

| X1.5 | X1.5 | X1.5 | — |
| X1.5 | X125 | — | — |
| 老化率10进对数时间 | 0 | 1% | 6% | 6% |
滤波电感
滤波电感一般采用铁氧体材料，它可以方便地与穿心电容组合起来，形成复合滤波器，
在高性能滤波器中，也采用线绕电感。但需注意，铁氧材料在大电流下会发生磁饱和，
降低滤波器效能。
