Capacitors covered by this specification are intended mainly for use in filter, bypass, coupling, blocking, and other low-voltage applications, such as transistor circuits, where stability, size, weight, and shelf life are important factors (see 6.1.1). Unless otherwise specified (see 3.1), these capacitors should not be used where continuous voltage reversals exceed 1 volt. The d.c. leakage and dissipation factor of the \suggested unit should be taken into consideration when designing transistor, timing, phase-shifting, and vacuum -tube -grid circuits.
