SNPO Series
APPLICATION:
FEATURES:
GENERAL SPECIFICATIONS:
The SNPO series has a high Q, low K
temperature compensating type of capaci-
tance dielectric with stable electrical
properties under varying voltage, temper-
ature, frequency and time conditions. The
series is suitable for circuits requiring low
loss, circuits with pulse, timing circuits
and for tuning applications.
Typically used in R/F, microwave, and
other communications equipment. Fre-
quently designed in precision industrial
controls, process control and test& mea-
surement instrumentation. Because of it's
wide range of temperature stability, often
used in automotive and quality audio
applications.

Voltage/Case Code Options
COG / NPO is a dielectric with stable electrical properties under varying voltage,
temperature, frequency and time.
This dielectric has the least value of temperature coefficient. The temperature
coefficient characteristics is illustrated in Figure 1.1 Figure 1.2 illustrates the
variation pattern of Dissipation Factor with respect to temperature.
The DC Voltage coefficient and AC Voltage coefficient are illustrated in Figures 1.3
and 1.4 respectively.
