If Rv be the resistance of the meter, the effective leakage resistance R'' would be given by R = R Rv R +Rv (5.4) The unwanted discharge through the meter can, therefore, be reduced only by making Rv much higher than R. This is accomplished in a simple way by using a higher voltage source and employing
Customer ServiceA capacitor comes with a set of characteristics. All these characteristics can be found in datasheets that are provided by capacitor manufacturers. Now let us discuss some of them. One of the most important one among all capacitor characteristics is the nominal capacitance (C) of a capacitor.
Elec-trical factors include operating voltage, ripple current and charge-discharge. Where the capacitors are used in a normal filtering circuit, ambient temperature and heating due to the ripple current are crucial factors for determining the lifetime of the capacitors.
Generally the capacitance value which is printed on the body of a capacitor is measured with the reference of temperature 250C and also the TC of a capacitor which is mentioned in the datasheet must be considered for the applications which are operated below or above this temperature.
For each series of capacitors, the following electrical parameters have been defined as criteria in the specifications of Endurance in the catalogs or product specifications: ・ Change in capacitance ・ Tanδ ・ Leakage current Failure rates are often measured in units of % per 1000 hours (10-5/hour).
The capacitance of a capacitor can change value with the circuit frequency (Hz) y with the ambient temperature. Smaller ceramic capacitors can have a nominal value as low as one pico-Farad, ( 1pF ) while larger electrolytic’s can have a nominal capacitance value of up to one Farad, ( 1F ).
Changes in temperature around the capacitor affect the value of the capacitance because of changes in the dielectric properties. If the air or surrounding temperature becomes to hot or to cold the capacitance value of the capacitor may change so much as to affect the correct operation of the circuit.
