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.
