Panasonic – Hybrid capacitors combine best features of polymer and electrolytic capacitors



Panasonic Automotive and Industrial Systems Europe offers a family of hybrid capacitors which combines the best characteristics of conductive polymer capacitors and aluminium electrolytic capacitors.

The ZA, ZC, ZK and ZE hybrid capacitors feature low Equivalent Series Resistance (ESR), a typical characteristic of polymer capacitors. They also have very low leakage current, an attractive feature that is commonly found in aluminium electrolytic capacitors.

Available with voltage ratings ranging from 25V to 80V, the Panasonic hybrids offer excellent endurance at high operating temperatures, and are available in a variety of case sizes and capacitance ratings.

The latest hybrid ZE series devices have a maximum temperature rating of 145°C, rivalling pure electrolytic capacitors for high- temperature performance while maintaining low ESR values.

In sensing applications, the transient response and ripple-voltage performance are enhanced by the hybrid devices’ low impedance. In fact, the ripple-current ratings of the hybrid capacitors are superior to those of electrolytic capacitors that have equivalent capacitance and voltage values.
