Electrical behavior of ceramic chip capacitors is strongly dependent on test conditions, most notably temperature, voltage and frequency. This dependence on test parameters is more evident with Class II ferroelectric dielectrics, and negligible or more easily predictable with Class I formulations.
Using a digital multimeter (DMM) along with proper testing techniques makes it possible to evaluate both large and small ceramic capacitors accurately. This guide covers step-by-step methods to properly test ceramic capacitors using an ordinary digital multimeter.
Testing ceramic capacitors is quite straightforward using just a basic digital multimeter. The required equipment includes: Digital multimeter (DMM) – A standard handheld DMM with capacitance measurement mode is ideal for testing ceramic caps. Models with a capacitance range of at least 100 μF are recommended.
