Panasonic's EEH-ZK(U) Series Conductive Polymer Hybrid Aluminum SMD Electrolytic Capacitors provide 20% larger capacitance in the same small case sizes reducing the number of Capacitors required. 


This Series goes beyond using large space-consuming axial, THT and SMD Capacitors to achieve low ESR requirements. Panasonic Hybrid Capacitors combine the advantages of Electrolytic Capacitors with those of solid Polymer Capacitors to provide reliant and across-the-board solutions in Automotive and Industrial applications alike.


This Hybrid technology offers low leakage current and long life in combination with low ESR in smaller case sizes. The EEH-ZK(U) Series parts are available in 25 and 35 V.DC options and are ideal when high temperature, high current capability, and small case size are being demanded by the application. AEC-Q200 qualification ensures optimal quality and reliability.
