Product Overview

The MAL212017221E3 is an axial leaded high temperature polarized Aluminium Electrolytic Capacitor feature non-solid electrolyte. The 120 ATC series low ESR capacitor provides very 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.
  • Cylindrical case
  • Insulated with a blue sleeve
  • Input buffer provides energy when mains input voltage is too low
  • Input buffer stores energy while AC/DC converter, e.g. PFC controller, adapts to a new power level
  • Input buffer prevents HF switching noise from the DC/DC converter reaching power source
  • Output buffer - Current sink for inductor (current to voltage conversion), filtering
  • Output buffer - Buffer energy while DC/DC converter adapts to changed power output
