WebImpedance Characteristics of Bypass Capacitor Application Note The following is a summary of key points in selecting the bypass capacitor. 1. Select a sufficiently large capacitance value so that the impedance is low at the noise frequency. The larger the capacitance value, the lower the impedance. 2. WebA further complication associated with external bypass capacitance is the ESR inside each capacitor. Acting as a small-value resistor in series with the internal capacitance, low ESR values are desirable to absorb load spikes. However, lower ESR capacitors may compromise the dynamic performance of the converter.
