| ELECTRONIC COMPONENTS - THE VOLTAGE RATING OF CAPACITORS | ||
In selecting a capacitor, consideration must be given to (1) the value of capacitance desired and (2) the amount of voltage applied across the capacitor. If the voltage applied is too great, the dielectric breaks down and the capacitor in effect becomes a short circuit and the direct current through it can damage other components. Each capacitor also has a voltage rating (a working voltage) that shouldn’t be exceeded. The working voltage is the maximum voltage that can steadily be applied without breaking down the dielectric. The working voltage depends on the type of material used as the dielectric and on the thickness of the dialectic. |
