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.
