UFW1V471MPD

The UFW1V471MPD is a radial‑lead aluminum electrolytic capacitor from Nichicon's UFW series, optimized for audio equipment. It delivers 470 µF capacitance at a 35 V rating in a compact φ10 × 16 mm aluminum can with 5 mm lead spacing.

Designed for applications that require substantial bulk capacitance, measurable ripple capability, and proven lifetime performance, this component balances size, ripple handling, and stability across a −40°C to 85°C operating range.

Key Features

• Capacitance & Tolerance — 470 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C).
• Rated Voltage — 35 V working voltage suitable for a wide range of audio and small power‑rail applications.
• Ripple Current Capability — 630 mA at 120 Hz (low frequency) and 945 mA at 10 kHz (high frequency), enabling handling of AC ripple in supply and signal circuits.
• Low Leakage — Leakage current specified at 493.5 µA, supporting stability for long‑term bias conditions.
• Temperature & Lifetime — Operates from −40°C to +85°C with a rated endurance of 2000 hours at 85°C, meeting long‑term reliability needs for sustained use.
• Package & Mounting — Radial lead, can‑style package (φ10 × 16 mm) with 5 mm lead spacing for through‑hole PCB assembly and robust mechanical mounting.
• Polarized — Standard electrolytic polarity for DC power and signal applications.
• Series Focus — Part of Nichicon’s UFW family, targeted for audio equipment applications.

Typical Applications

• Audio Power Supplies — Bulk smoothing and decoupling in power rails for amplifiers and audio peripherals where compact, high‑capacitance parts are required.
• Amplifier Stages — Coupling and supply stabilization in preamplifier and power amplifier circuits within consumer and pro‑audio equipment.
• Consumer Audio Devices — Power filtering and energy storage in compact audio electronics and accessories that operate across a wide temperature range.

Unique Advantages

• Compact high capacitance: 470 µF in a φ10 × 16 mm can minimizes board real estate while providing substantial charge storage.
• Measured ripple performance: Dual ripple ratings (630 mA @120 Hz and 945 mA @10 kHz) make the capacitor suitable for both low‑ and high‑frequency ripple environments.
• Long operating life at elevated temperature: 2000 hours rated life at 85°C supports reliable operation in sustained thermal conditions.
• Wide operating temperature: −40°C to +85°C supports use across typical environmental ranges encountered in audio equipment.
• Low leakage current: Specified leakage of 493.5 µA helps maintain bias stability in DC‑coupled circuits.
• Robust through‑hole packaging: Radial lead, can construction with 5 mm lead spacing provides secure mechanical mounting and straightforward PCB insertion.
