Electrical behavior of ceramic chip capacitors is strongly dependent on test conditions, most notably temperature, voltage and frequency. This dependence on test parameters is more evident with Class II ferroelectric dielectrics, and negligible or more easily predictable with Class I formulations.
The rated voltage depends on the material and thickness of the dielectric, the spacing between the plates, and design factors like insulation margins. Manufacturers determine the voltage rating through accelerated aging tests to ensure the capacitor will operate reliably below specified voltages and temperatures.
In addition, the dielectric voltage withstand test may reveal faults in mechanically damaged insulation or the presence of a foreign material (such as water) which may bridge the insulation. This test is often used after mechanical abuse or temperature tests to confirm that the product has maintained its insulating capabilities.
As a general rule, a properly designed capacitor of sound construction should withstand the normal 25°C dielectric withstanding flash voltage even when the temperature is 125 ° C.
Capacitors have a maximum voltage, called the working voltage or rated voltage, which specifies the maximum potential difference that can be applied safely across the terminals. Exceeding the rated voltage causes the dielectric material between the capacitor plates to break down, resulting in permanent damage to the capacitor.
Various techniques and dielectric materials enhance capacitor voltage handling capabilities: Thick dielectrics withstand higher voltages, but reduce capacitance density. High purity, low defect solid dielectrics like diamond have excellent strength. Polymer impregnation fills voids within film or ceramic dielectrics.
