Aluminum Electrolytic Capacitor Selection Chart
KEMET's Aluminum Electrolytic Capacitors include axial, snap-in and screw-terminal types. These capacitors offer very long life in applications requiring high ripple currents and temperatures up to 150°C. Other models have rated voltages as high as 550 VDC.
In addition to those products shown in the datasheets, KEMET can optimize the construction to offer application-specific balance between required life, temperature, ripple current, physical size, and cost.
Motor start capacitors are also offered.
