Panasonic's EEH-ZK series are conductive polymer hybrid aluminum SMD electrolytic capacitors. Using large, space-consuming, axial THT and SMD capacitors to achieve low ESR requirements and good EMC behavior is old-fashioned. Panasonic's 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 voltage range of 25 V to 80 V caters to the capacitor industry standard temperature rating of -55°C to +105°C (ZA series) and -55°C to +125°C (ZC and ZK series). Ripple current rating (RCR), which is the decisive factor for a lot of capacitance agnostic applications, finds dramatic improvement for long lifetimes of 10,000 hours at +105°C and 4,000 hours at +125°C. Endurance at 3,000 hours at +125°C allows the possibility to augment the RCR up to 1.5 times. AEC-Q200 qualification ensures optimal quality and reliability. The EEH-ZC series parts are available in 25 V_DC and 35 V_DC and are ideal when high temperature and high current capability are being demanded by the application.
