330uF 25V Aluminum Electrolytic Capacitor

330uF 25V Aluminum Electrolytic Capacitor

The 330uF 25V aluminum electrolytic capacitor is designed for power supply smoothing, filtering, and decoupling in low-voltage electronic circuits. Rated at 330 µF capacitance and 25 VDC, this capacitor delivers reliable performance in DC‑DC converters, SMPS, audio amplifiers, and general electronics that require stable voltage buffering.

Constructed with a polarized aluminum dielectric and a non-solid electrolyte, the 330uF 25V capacitor offers low impedance at low frequencies and a substantial energy storage capacity. Typical products in this category, such as the Panasonic EEUFC1E331CY or models from Samwha and Aishi, are rated for operation at 105 °C with a tolerance of ±20%, ESR values around 0.17 Ω, and ripple currents up to about 600 mA.

Standard radial and SMD variants offer compact dimensions—for example, Panasonic models measure roughly 8 mm diameter × 12.5 mm length, with lead spacing of 5 mm, while Samwha radial versions may be around 8 mm × 11.5 mm in size. These capacitors are RoHS compliant and widely available from brands such as Panasonic, Vishay, KEMET, and Samwha.
