4. Storage Life: A storage life of 10 years or more, with no
voltage at room temperature, may be expected.
5. Series Operation: These capacitors may be used in
some series applications. For such an application to
achieve a high voltage rating (e.g. 28 μF, 250 V using two
56 μF, 125 V capacitors), a suitable balancing network of
resistors in parallel with the capacitors is required to
evenly distribute the voltage across each capacitor. The
value of the appropriate resistor will be dependent on the
DC leakage current of the capacitors and, as
recommended value, it should be selected to allow a
current equal to 10 times the DC leakage current limit
(see Standard Ratings and Extended Ratings table at the
appropriate temperature) to flow parallel to each
capacitor.
