VISHAY  MAL215947221E3  铝电解电容, 摁入式, 159 PUL-SI系列, 220 µF, ± 20%, 450 V, 30 mm, 0.42 ohm

The is a power ultra long life snap-in keypad polarized Aluminium Electrolytic Capacitor feature non-solid electrolyte. The 159 PUL-SI series electrolytic capacitor provides low ESR and high ripple current capability. In general, aluminium capacitor is the most suitable capacitor 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. An electrochemically etched aluminium anode foil forms the first plate of the capacitor. An oxide layer on the etched aluminium foil that forms the dielectric. A paper spacer impregnated with fluid electrolyte in contact with the oxide layer to form the second plate of the capacitor. A second foil that forms the other contact with the fluid electrolyte.
