Another way to measure the capacitance is to include the unknown capacitor in a resonance circuit. The resonant frequency depends on the value of the capacitor and the inductor. With the in-circuit measurement, looking at the ESR, it can be mistaken for a good capacitor. Table 1 also shows the deviation from the nominal capacitor impedance, in ohms, for various tolerances and lists impedance deviations from 50 ohms as a percentage for all capac - itance values listed. Their main function is to fix the resonant frequency in the LC circuit. If you combine an inductor with a capacitor, you get a tuned circuit that resonates. Vishay customers can input information about applications, ambient temperature, operating voltage, and environmental factors to create multipliers . For most standard motors, a run capacitor will have a "tolerance" specified describing how close to the rated capacitance value that the actual value may be. If a capacitor with nominal capacitance of 22µF and voltage rating of 16V is chosen, as the nearest standard value above 19.22µF, the actual capacitance of this device is 5.951µF at 400kHz, as shown in figure 1, and the ESR is 3.328mΩ.
