Electrolytic Capacitor, Long Life, 4700 µF, 40 V, ± 20%, Snap-In, 12000 hours @ 85°C - 

The MAL205657472E3 is a power standard miniature polarized snap-in Aluminium Electrolytic Capacitor features low ESR and non-solid electrolyte. The 056 PSM series electrolytic capacitor provides high ripple current capability. In general, aluminium capacitor is the most suitable capacitors for addressing requirements such as low and high frequency filtering and energy storage, which demand high capacitance values and power ratings. The device offers high CU/(unit cost) ratios, is small compared with other technologies and is relatively insensitive to voltage spikes. While it is easy to regard aluminium capacitors as commodity products, they are, after inductors, often the most expensive passive components in the power supply. Because of this, designers must pay careful attention to selection. Circuit simulation programs further complicate the situation, as they cannot easily handle frequency dependent component characteristics.
