Cornell Dubilier Electronics Inc. has expanded its SPCX and SPSX series of surface mount aluminum polymer capacitors.
Both series are now available with lower ESR and higher capacitance values for board-level power-conversion applications.
Both types are supplied in a surface mount molded package with the same footprint as a D size tantalum capacitor. The package’s thin profile measures 1.9 mm. Both series also offer voltage values ranging from 2.0 to 6.3 Vdc.
Type SPCX is considered the general-purpose series with capacitance values ranging from 100 µF to 470 µF and ripple current capability up to 3.0 A at 105 °C. Ultra low ESR type SPSX has ESR values as low as 4.5 milliohms, allowing them to handle up 4.0 A of ripple current at 105 °C. Capacitance values range from 82 µF to 560 µF.
