OpenCVMeter is an open source tool to measure capacitance and leakage current as a function of a capacitor’s working voltage.
When designing circuits, many hobbyists take capacitors for granted – but each type (ceramic multi-layer, aluminum electrolytic, tantalum, mica…) has its own unique properties. Nowadays, ceramic capacitors are the most commonly used capacitors in the industry, but many can lose up to 80% of their rated capacitance near their voltage ratings.
Enter the OpenCVMeter! This meter aims to provide a Capacitance versus Voltage characterization accurate within 1% of the capacitors for your next project (or already have and are starting to wonder about right now…)
