AEC-Q200 Polymer Hybrid Aluminum Capacitors Provide 20% Increase in Capacitance

August 14, 2019 by Paul Shepard

Panasonic has announced the new EEH-ZK(U) series Conductive Polymer Hybrid Aluminum SMD Electrolytic Capacitors. These new devices provide 20% more capacitance in the same case sizes reducing the number of capacitors required.

According to Panasonic, using large space-consuming axial, THT and SMD Capacitors to achieve low ESR requirements and good EMC behavior is passé. Panasonic Hybrid Capacitors, combining the advantages of Electrolytic Capacitors with those of solid Polymer Capacitors, have established themselves as reliant and across-the-board solutions in Automotive and Industrial applications alike.

Hybrid technology offers low leakage current and long life in combination with low ESR in smaller case sizes.

The New EEH-ZK(U) Series parts are available in 25- and 35-Vdc and are well-suited when high temperature, high current capability and small case size are being demanded by the application. AEC-Q200 qualification ensures optimal quality and reliability.
