Capacitor manufactures specify voltage and frequency parameters for measurement of Class-II and Class-III ceramic capacitors. In order to determine whether a capacitor meets its rated specification, it is critical to measure the part
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.
• Frequency discriminating where “Q” and stability of capacitor Test Temperature: 25°C ± 2°C. characteristics are not of major importance. The DF shall not be greater than 2.5% for Y5E, Y5P & Z5U. The DF shall not be greater than 5% for Y5V & Z5V. 7500M minimum. Shall be measured after 1 minute at rated voltage.
Use a high wattage resistor rated for the cap voltage to slowly drain charge over ~1 minute before shorting terminals. This avoids arcing risks. Introduction Ceramic capacitors are common passive components found in all types of electronic circuits.
Select the appropriate capacitance range on the DMM that matches the capacitor value you are measuring. For example, choose the 20 μF range for testing a 0.1 μF capacitor. 4. Connect test leads Securely attach the black and red multimeter probes to the capacitor terminals. Ensure metal contact with no insulating oxides present. 5.
Use shortest leads possible or compensate for lead capacitance. If a ceramic capacitor measures open circuit, could it still potentially operate in a circuit temporarily? Damaged ceramic capacitors can occasionally conduct intermittently before fully failing open. So do not assume an open measurement guarantees the cap is inert.
Accurately measuring picofarad-size ceramic capacitors presents challenges due to their extremely low values. Testing small capacitors requires: Using a DMM with resolution down to at least 10 pF range. Zeroing out stray test lead capacitance as described above. Employing a test fixture that immobilizes the component.

Multilayer ceramic capacitors (MLCCs) are generally the capacitor of choice for applications where small-value capacitances are needed. They are used as bypass capacitors, in op-amp circuits, filters, and more. Advantages of MLCC include: Small parasitic inductance give better high-frequency performance compared to aluminum electrolytic capacitors.
