The MAL215371101E3 is a SMD (chip) long life polarized Aluminium Electrolytic Capacitor feature non-solid electrolyte and self healing property. The 153 CRV series SMD-version is available with base plate, vertical construction requiring minimum board space, lead (Pb)-free reflow solderable. 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 fluid electrolyte.
- High CV per unit volume
- Charge and discharge proof, no peak current limitation
- 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
