PEG Electrolytic Capacitors KEMET PEG Electrolytic Capacitors feature a polarized, all-welded design with tinned copper wire leads and a negative pole connected to the case. The winding is housed in a cylindrical aluminum can with a high-purity aluminum lid and high-quality rubber gasket. This low resistive electrolyte/paper system and all-welded design results in low ESR. KEMET PEG Electrolytic Capacitors are suitable for use in mobile and aircraft installations with an operating temperature up to +150°C. Some of these PEG series are AEC-Q200 qualified, making them ideal for automotive applications with demanding requirements.
