SP-Cap Polymer Aluminum

Make your product Powered by Panasonic

Modules that exceed expectations!

SP-Caps are Surface Mount Aluminum Electrolytic Capacitors that use a conductive polymer as their electrolyte material. SP-Caps are primarily used as input and output capacitors for DC/DC converters due to their ultra low ESR values. Panasonic SP-Caps offer excellent performance for moderate to high capacitance and voltage values at low cost.

LINE EXTENSION! EEF-SS, EEF-ST, EEF-LS, EEF-LT, EEF-CS and EEF-CT Series SP-Cap Specialty Polymer Aluminum Capacitors

New Lower Profile, Stable Capacitance At Higher Frequencies and Temperatures
Panasonic, a worldwide manufacturer of Capacitor Products, introduces the expansion of the SP-CAP&g; product line in the EEF-xx Series. Panasonic’s SP-CAP layered aluminum technology now provides an even lower profile and high stable capacitance at higher frequencies and temperatures. SP-Caps are ideal for A/V, PC and hand held consumer applications. These parts are well suited for applications where the capacitor must meet very strict height restrictions.
