Dielectric Characteristics
API offers SMPS capacitors in two basic dielectric
classes, with individual designs tailored to meet specific
performance characteristics.
Dielectric Type
BP
(NPO/COG)
Stability
Class
Ultra Stable
Class I
E
D
A
Description
Effects on electrical properties are
minimal with variations in operating
temperature, voltage, frequency or
time. Used in applications which
require stable performance.
Class II dielectrics will exhibit a
predictable shift in performance
characteristics when exposed to
variations in temperature, voltage,
frequency or time. Selected for
applications where blocking,
coupling, by-passing and frequency
discriminating elements are used.
Offers higher capacitance than
Class I (COG).
