摘要
钽电容的应用领域逐步扩大,所应用的场景也越来越多,受限于固体钽电容的耐压及应用降额的限制要求,固体钽电容仅在耐压较低的电路中使用,进行储能或者滤波。在工作电压相对较高的电路中,一般采用串联的方式提高耐压。钽电容不同于电阻等元件,电容具有储能作用,在电路中不能简单的看做串联后得到了更高耐压的电容。应注意串联后的分压不均和断电时电容放电过程造成的影响。Abstract: The application field of tantalum capacitor is gradually expanding, and there are more and more application scenarios. Limited by the withstand voltage and application derating requirements of solid tantalum capacitor, solid tantalum capacitor is only used in circuits with low withstand voltage for energy storage or filtering. In the circuit with relatively high working voltage, series connection is generally used to improve the withstand voltage. Tantalum capacitors are different from resistors and other components. Capacitors have the function of energy storage. They can not be simply regarded as capacitors with higher withstand voltage after being connected in series in the circuit. Attention shall be paid to the influence of uneven partial voltage after series connection and capacitor discharge process during。
