Low-resistance applications and voltage networks

For low-resistance applications, KEMET recommends a maximum operating voltage of half the

permissible maximum continuous voltage, so that the capacitors have sufficient tolerance to

withstand voltage peaks. Depending on the conditions of use, the early failure rate is higher here

by a factor of 2 to 20 than in the range with a constant failure rate as specified in the data book.

When operated directly in a voltage network, the capacitor should be protected against

overvoltage, e.g. by a suppressor diode, and against polarity reversal by a diode. If a capacitor is

operated in an unprotected low-impedance circuit and fails because the permissible conditions for

the forward DC voltage, reverse DC voltage, surge current, power dissipation or temperature are

exceeded, the continued current flow through the overstressed capacitor may produce

overheating. The overheated capacitor may damage the surrounding components and the circuit

board.

Storage conditions

Capacitors with solid electrolyte may be stored at temperatures down to –80 °C. The upper

storage temperature must not exceed +85 °C (for blister tape the temperature limit is +40 °C).

The storage conditions should not exceed +40 °C and 70% R. H. A drypack is useful to prevent

the effects of humidity.
