Polymer Capacitors Cloud & AI Applications

KEMET Organic Capacitors (KO-CAP®) provide an ideal solution for applications requiring power-loss (hold up) protection or maximum power efficiency of a circuit with limited board space. Polymer technology offers high energy density and extended life capabilities, making it a key solution for designers working in cloud infrastructure applications like solid-state drives, 5G, and servers. In addition, with the AI computing edge trend pushing for high power, KEMET KO-CAPs are vital on 12V input and low voltage 1V CPU and I/O 3.3V and 5V power rails. These capacitors offer both long life and high ripple capability.
