Many applications require the use of RFI (Radio Frequency Interference ) X2 capacitors with high stability in harsh environmental conditions e.g. general-purpose applications in series to the mains (capacitive voltage dividers, energy meters) and automotive ones (battery chargers). KEMET released recently a new fully-approved RFI X2 metallized film series, suitable for both series and parallel- to-the-mains connection, designed for high capacitance stability in harsh conditions.
Smart meters have expected operational lifetime of 10 to 15 years once installed. As a result, components with long life and virtually no-wear out mechanism in high humidity environments are required.
