Y5U -30°C ~ +85°C +22% / -56% ±20%
Y5V -30°C ~ +85°C +22% / -82% ±20%
Z5U +10°C ~ +85°C + 22% / -56% ±20%
Z5V +10°C ~ +85°C + 22% / -82% +80% / -20%

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.
