How to Measure Capacitance and ESR
element14 Presents | Bald Engineer: James Lewis' VCP Profile | Workbench Wednesdays
An obvious measurement for a capacitor is its capacitance. However, knowing its ESR is critical in design work and an important troubleshooting clue. Capacitors with high ESR can cause significant ripple voltage and can indicate a capacitor near the end of its useful life. The Atlas ESR70 makes quick work of measuring a capacitor's ESR.
