SP-Cap

SP-Cap capacitors feature low ESR, low ESL, long life span, small size, low profile, and high characteristic stability.

SP-Cap - conductive polymer aluminum electrolytic capacitors

SP-Caps are surface mount aluminium 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 applications that require moderate to high capacitance and voltage values at low cost.

Panasonic polymer capacitors: an alternative to MLCCs & tantalum capacitors

Electrolytic capacitors with conductive polymer technology meet the needs of a wide range of electronic applications

SP-Cap, POSCAP, OS-CON, and hybrid capacitors use a highly conductive polymer to achieve low equivalent series resistance(ESR), excellent noise reduction capability and ideal frequency characteristics.
