Engineering Bulletin
Aluminum Solid Capacitors
Feature
!
@Super low ESR, impedance and high heat resistance have been obtained by using
conductive polymer as electrolyte.
(ESR and rated ripple current values are improved from PXA series.)
@Rated voltage range : 2.5 to 16Vdc, Capacitance range : 27 to 470MF
@Case size range : F5B6.0mm to F8B7.0mm
Pb Free Type
@Suitable for DC-DC converters, voltage regulators and decoupling applications used to
computer motherboards etc.
