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.
