Why is measured capacitance different from nominal capacitance?
Capacitance of ceramic capacitors changes by temperature, voltage, frequency, aging and so on. Nominal capacitance is measured under conditions described in the catalog. If you measure the capacitance under the different condition, the result is not always correspond to nominal capacitance. About our products, you can confirm the capacitance change by temperature, voltage and frequency in TY-COMPAS.
Also, the characteristics of used jigs is contained in the measurement result. Therefore, you must remove the influence of measurement jigs to get accurate capacitance. Please refer to the manufacturer's manual for the method of compensation.
