Capacitor ESR Measurement


The equivalent series resistance of a capacitor (ESR) is not always specified by the manufacturer. The Bode 100 with its impedance adapters offers an easy and fast way of measuring the ESR over frequency.

This application note shows how to use the Bode 100 in conjunction with the B-WIC impedance test fixture to measure the ESR of an aluminum electrolytic capacitor. The data is compared to the information available in the manufacturer's datasheet. Check out the document below to find out more.
