PEH Screw Terminal Aluminum Electrolytic Caps KEMET Electrolytic Capacitors contain a radial crown, which allows the capacitors to be mounted in a standing position. They feature a polarized, all-welded design with outstanding electrical performance, tinned copper wire leads, a negative pole connected to the case, and plastic insulation. The winding is housed in a cylindrical aluminum can with a high-purity aluminum lid and a high-quality rubber gasket. Low ESR is a result of a low resistive electrolyte/paper system and an all-welded design. KEMET Electrolytic Capacitors are suitable for use in mobile and aircraft installations with operating temperatures up to +150°C, depending on the model.
