With 470 µF capacitance at 35V DC rating, this capacitor is designed for power supply smoothing and general-purpose filtering applications. The 105°C endurance rating with 2,000-hour lifetime ensures reliable operation in demanding environments, while AEC-Q200 compliance confirms suitability for automotive powertrain and safety equipment. The solvent-resistant construction enables compatibility with standard PCB cleaning processes. The compact 12.5mm diameter SMD package provides high capacitance density for space-constrained designs.

Principio de funcionamiento:EMVE350ARA471MKE0S Principio de funcionamiento

The EMVE350ARA471MKE0S operates as a polarized aluminum electrolytic capacitor:

1. Capacitance Mechanism: The capacitor uses an aluminum oxide dielectric layer formed on the anode foil surface, with a conductive electrolyte serving as the cathode. The extremely thin oxide layer (nanometers thick) provides high capacitance per unit area.

2. Voltage Rating: The 35V DC rating is determined by the thickness of the aluminum oxide dielectric, which is formed through anodization during manufacturing.

3. Ripple Current: The 520 mA ripple current rating at 105°C is determined by the capacitor’s equivalent series resistance (ESR) and its ability to dissipate heat. Exceeding this rating causes excessive internal heating and accelerated degradation.

4. Endurance: At 105°C with rated voltage applied, the capacitor maintains capacitance within ±20% and dissipation factor within 200% of initial values for 2,000 hours.
