How to Measure Capacity Versus Bias Voltage on MLCCs

By: Fons Janssen

摘要 : The application note explains how to always check the capacitor’s datasheet to see how the capacitance varies with the bias voltage. Using the presented circuit, a dual power supply, and a voltmeter, it is quite simple to measure the DC bias characteristic of a high-capacity MLCC.
