Surface-Mount Aluminum Electrolytic Capacitors KEMET Surface-Mount Aluminum Electrolytic Capacitors are designed for a variety of applications where low impedance, a low profile, and a wide operating temperature range are required. Both EDH and EDK capacitors are engineered for use on high-density printed circuit boards. The EDT series is ideal for applications with high operating temperatures. Applications that require a low-profile vertical chip are best served with the EDT, EEV, and EXV series. KEMET Surface-Mount Aluminum Electrolytic Capacitors have a lifetime of up to 5000 hours.
