UCA2V470MHD

The UCA2V470MHD is a radial‑lead aluminum electrolytic capacitor in Nichicon's UCA series, offering a compact 47 µF capacitance at a 350 V rated voltage. Designed for high ripple current and long operational life, it targets power conversion and lighting ballast applications where high‑voltage smoothing and reliable ripple handling are required.

Its miniature can package (φ16×25 mm) and 7.5 mm lead spacing make it suitable for through‑hole power supply assemblies and general‑purpose high‑voltage DC circuits, while the -25 °C to +105 °C operating range and 12,000 hour load life at 105 °C support sustained thermal operation.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 350 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• High ripple current capability — Rated ripple currents of 350 mA at 120 Hz and 700 mA at 100 kHz (105 °C) to handle heavy AC ripple in power circuits.
• Long operational life — Load life specified at 12,000 hours at +105 °C, providing extended service in thermally stressed applications.
• Compact radial can package — φ16×25 mm can size with 7.5 mm lead spacing and radial leads for through‑hole assembly.
• Electrical loss and leakage — Tangent of loss angle (tan δ) specified at 0.20 (measurement: 120 Hz, 20 °C) and leakage current specified as 758 µA after 1 minute at 20 °C under rated voltage.
• Wide operating temperature — Rated for operation from -25 °C to +105 °C for a broad range of industrial environments.
• RoHS compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supplies — DC smoothing and ripple suppression in medium‑to‑high voltage power supply designs.
• Lighting ballasts — AC ripple handling and DC link support for electronic ballast circuits.
• General high‑voltage DC circuits — Through‑hole radial mounting for industrial and commercial high‑voltage smoothing and filtering.

Unique Advantages

• High ripple tolerance: Rated for 700 mA at 100 kHz (105 °C), enabling reliable performance under significant AC ripple stress.
• Extended life under thermal load: 12,000 hours at +105 °C supports long‑term deployments in hot operating environments.
• Compact footprint: φ16×25 mm radial can provides a small through‑hole solution for space‑constrained power assemblies.
• Clear electrical characterization: Specified tan δ (0.20) and measured leakage (758 µA) allow predictable thermal and leakage budgeting in designs.
• RoHS compliance: Meets current RoHS requirements for use in regulated manufacturing environments.
