Z5U Dielectric
General Specifications
Z5U formulations are “general-purpose” ceramics which are
meant primarily for use in limited temperature applications
where small size and cost are important. Z5U show wide
variations in capacitance under influence of environmental
and electrical operating conditions.
Despite their capacitance instability, Z5U formulations
are very popular because of their small size, low ESL, low
ESR and excellent frequency response. These features are
particularly important for decoupling application where only a
minimum capacitance value is required.
