Conductive Polymer Hybrid Aluminum Electrolytic Capacitors

Zoom

Achieves low ESR, high withstand voltage, and high reliability through the use of the "hybrid electrolyte" consisting of conductive polymer and electrolytic liquid.

Products with vibration-resistance specifications can also be produced (ø6.3 ≤).

What is Conductive-Polymer Hybrid Aluminum Electrolytic-Capacitor

Capacitor achieved both high performance and high reliability

Capacitor with the electrolyte fused with conductive polymer and electrolyte liquid
As features of both conductive polymer and electrolyte liquid, large ripple current(low Equivalent Series Resistance : ESR), low leakage current and high reliability contribute to downsizing and high reliability of the equipment
Suitable for automotive equipment and base stations which need compact and high reliability components.
