The capacitance should be measured at 20°C with 1±0.2MHz and AC5V(r.m.s.) max. The Q should be measured at 20°C with 1±0.2MHz and AC5V(r.m.s.) max. The capacitance measurement should be made at each step specified in Table. The capacitance measurement should be made at each step specified in Table. Lead wire should not be cut off.
In each of the main simulations, the object is swept over the electrode with a moving step of 1 mm. The measurement is started when the object is about to enter the No. 1 electrode, and the measurement ends when the object completely leaves the No. 2 electrode. Each time the object moves, the capacitor values that are measured are saved.
To test a capacitor, select the capacitor setting on the multi-meter. This is normally under resistance and is often displayed as nF as the unit on the screen. Hold the test leads on 'A' and 'B'. Hold the test leads on the terminals of the capacitor, 'A' and 'B', for testing. It normally takes a few seconds to get an accurate reading. Compare the reading you get from the multi-meter to what is specified on the casing of the capacitor.
Capacitance measurements are especially common when the method of actuation is by capacitors as well. By utilizing a high frequency voltage on the capacitors, one can measure the impedance. Equation 1 is for the capacitance due to parallel plate capacitors and Eq. 3 is for comb capacitors.
It’s important that designers be able to make their own ESL measurements. With ESL values typically in the range of 1 nH to 5 nH, measuring the ESL of chip capacitors is not a trivial task. At present, some designers try to measure ESL by measuring the resonant frequency of the capacitor, and calculating inductance from that reading.
The key to measure the capacitance and dissipation factor correctly is the meter settings (see Table 1). Table 1: Frequency and voltage settings for different capacitance range and class types. The voltage settings are very critical for high capacitance capacitors.
