Z5U & Y5V DIELECTRICS
General purpose EIA Class III dielectrics with +22% to
-56% (Z5U) and +22% -82% (Y5V)
temperature coefficients and very high capacitance density. The NOVACAP Z5U and Y5V
formulations are very stable with time, typically aging less than 2% per decade. General
purpose chips are used in by-pass and decoupling functions and other applications where
capacitance change over the operating temperature range is not critical.
Note: Flexicap® is the preferred termination for Class III Z5U and Y5V dielectrics to
reduce the chance of mechanical cracking due to board flexure.
