The Panasonic EEFSX0D471E4 is a 470 uF conductive polymer aluminium Electrolytic Capacitor from the SX series, built in a surface-mount 2917 (7343 metric) case. Polymer aluminium construction gives it a low equivalent series resistance of 4.5 m Ohm, well below that of comparable wet electrolytic parts. The capacitance tolerance is 20 percent and the part is rated for operation from -55 C to +105 C with a 2, 000 hour life rating. It is RoHS compliant, lead free, tin plated, and supplied on tape and reel in quantities of 3, 500.

Polymer aluminium Electrolytic Capacitors like the EEFSX0D471E4 are used where high capacitance and low ESR are needed in a low-profile surface-mount body, most often as output bulk decoupling on point-of-load DC-DC converters and as input filtering on high-current rails. The 4.5 m Ohm ESR helps suppress switching ripple and improves transient load response. Typical users include power supply designers for servers, networking hardware, industrial controls, and automotive electronics. The -55 C rating extends its use into cold-environment and telecom outdoor equipment.
