LCFesR meter is a precise, wide range meter that can measure inductivity (L), capacity (C), frequency (F) and equivalent series resistance of a capacitor in-circuit (ESR) based on AVR ATMega88PA-PU microcontroller. It can be easily built with homemade one or double-faced PCB and available electronic components. dr. Le Hung, project designer, explained that measurement of […]

Capacitor ESR Tester

ESR (equivalent series resistance) is one of the characteristics that define the performance of an electrolytic capacitor. Low ESR is highly desirable in a capacitor as any ripple current through the capacitor causes the capacitor to heat up due to the resistive loses. Typical capacitor checker measures the capacity of the test capacitor. Some advanced […]
