Type SPCX/SPSX Surface Mount Aluminum Polymer Capacitors


Cornell Dubilier announces its product line expansion of types SPCX and SPSX surface mount aluminum polymer capacitors. Both series are not available with lower ESR and higher capacitance values making them among the best performing filter capacitors 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 capacitors in a very thin profile of 1.9mm with voltage values ranging from 2.0 to 6.3 Vdc.

Type SPCX is the most economical, general purpose series with capacitance values ranging from 100 uF to 470 uF and ripple current capability up to 3.0 A at 105ºC. The solid polymer SPCX aluminum capacitor is an ideal choice for general purpose applications in audio-visual equipment, home appliances, computers, office equipment, optical and measuring equipment, and industrial robots. The SPCX is a very cost-effective capacitor in a compact low-profile package that is offered on tape and reel. The SPCX is environmentally green and RoHS compliant. 

Ulta low ESR type SPSX has ESR values as low as 4.5 milliohms, allowing them to handle up to 4.0 A of ripple current at 105ºC. Capacitance values range from 82 uF to 560 uF. The solid polymer SPSX aluminum capacitor is an ideal choice for audio/visual equipment, home appliances, computers, measuring equipment, and industrial robots. Like the SPCX, the SPSX is a compact component. But SPSX offers a much lower ESR and a higher ripple current rating than the SPCX. The SPSX is a green product and RoHS compliant.
