14、stics 2 Additional information (not for inspection purposes) The reliability of these capacitors depends on circuit impedance. In very low impedance (e.g. less than 37 V) circuits, such as power supplies, particular care is necessary to ensure that the surge voltage rating is not exceeded. This may
15、necessitate voltage derating of up to 50 %. The main mode of failure is high leakage current or short circuit. These capacitors may not meet the above mechanical severities when mounted solely by their leads. This type of capacitor is designed to operate over the temperature range 55 C to + 85 C and
16、 with proper derating to + 125 C (see Table 3A and Table 3B).
