摘要
阻抗特性是电子元件在电子线路应用中一个重要的参数。当电容器处于交流电路中时,电容器会成为一个有阻力的元件,它的阻抗特性即是描述这种阻力现象的参数。一般电容器用于滤波或平滑作用时,电容器会流过一纹波电流,此纹波电流会导致电容器内部温度升高而直接影响到电容器的使用寿命。
Impedance characteristic is an important parameter of electronic components using in electronic circuitry. When a capacitor used in AC circuit, it will be a component with resistance. Its impedance characteristic describes this phenomenon. Ripple current will pass through it. When the capacitor used for filtering and smoothing, ripple current will result in the enhancement of temperature inside the capacitors, and reduce the capacitors?life.
