Polymer Capacitors Industrial Segment

KEMET Organic Capacitors (KO-CAP®) offer higher voltages in smaller case sizes and are ideal for industrial applications. These capacitors deliver a solution for applications requiring power-loss protection or maximum power efficiency of a circuit when board space is limited. The polymer technology provides these capacitors with extended life capabilities in applications subject to extremely harsh environments.
