Conductive Polymer Electrolytic Capacitors
KEMET Electronics Conductive Polymer Aluminum Solid Electrolytic Capacitors are designed for greater stability and longer life. These single-ended and surface-mount capacitors promote a number of qualities superior to standard electrolytic capacitors (E-caps). These features include high conductivity, a solid polymer electrolyte, and generating less heat internally during operation. KEMET Conductive Polymer Aluminum Solid Electrolytic Capacitors also provide low ESR and higher ripple capability, open failure mode, and stability across a wide range of temperatures.
