Application Notes (Ceramic):
NPO: Has a very
low dissipation factor and are very stable over wide
variations in temperature, frequency, voltage, and
time. NPO type capacitors are frequently used for
precision timing, filtering, frequency setting, and
tuning circuits.
X7R: Are used when
some capacitance variation is allowed and the dissipation
factor is not critical. X7R type capacitors are frequently
used for bypass, decoupling, filtering, frequency
discrimination, timing, DC voltage blocking, voltage
transient suppression, instrumentation, computers,
telecommunications, and automotive electronics.
Z5U: Dielectrics
have the highest capacitance for their size. Z5U type
capacitors have applications in bypass, decoupling,
transient suppression, computers, and telecommunications.
