In applications where space is at a premium, multiple discoidal capacitors can be integrated into a single piece of ceramic referred to as a capacitor array and installed in a feedthrough for device integration. These types of filtered feedthrough assemblies provide the highest concentration of filters in the smallest
Film Capacitors
The test voltage of a capacitor is higher than the rated DC voltage and may only be applied for a limited time. The dielectric strength is measured between the electrodes with a test voltage of 1.5 x UNDC for 10 s, at metalized film capacitors and of 2 x U NDC at film/foil capacitors for typically 2 s.
