UFW1C471MPD

The UFW1C471MPD is a Nichicon UFW series aluminum electrolytic capacitor in a radial-lead can, specified at 470 µF and 16 V. It is designed for audio equipment and related electronics that require bulk capacitance in a compact, through-hole package.

Key attributes include a ±20% capacitance tolerance, rated operation from −40°C to 85°C, a 2000 hour endurance at 85°C, and defined ripple current and dissipation factor figures for reliable power-rail filtering and decoupling in audio applications.

Key Features

• Capacitance & Rated Voltage — 470 µF nominal capacitance at a rated voltage of 16 V, with ±20% tolerance (120 Hz, 20°C).
• Dissipation Factor (tan δ) — tan δ up to 0.20 at 16 V (measured at 20°C, 120 Hz), providing a quantified loss characteristic for design calculations.
• Ripple Current Performance — Rated low-frequency ripple current of 420 mA at 120 Hz and high-frequency ripple current of 630 mA at 10 kHz, supporting both power-supply smoothing and high-frequency decoupling tasks.
• Leakage Current — Specified leakage current of 225.6 µA, measurable after voltage application for predictable idle current behavior.
• Endurance & Temperature Range — 2000 hours life at 85°C; operating range from −40°C to 85°C for stable performance across common audio equipment environments.
• Radial Lead, Compact Package — Can size φ8 × 11.5 mm with 3.5 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assembly and straightforward mechanical placement.
• Packaging Options — Available in Bulk (No Terminal Forming) or Bag packing to suit assembly and stocking preferences.

Typical Applications

• Audio power-supply filtering — Use the 470 µF capacitance and 420 mA ripple rating at 120 Hz to smooth and stabilize audio supply rails.
• Amplifier decoupling — Provides bulk decoupling for preamplifiers and power amplifiers in consumer and professional audio designs.
• Compact through-hole assemblies — The φ8 × 11.5 mm radial-can package and 3.5 mm lead spacing fit space-constrained PCB layouts requiring through-hole components.

Unique Advantages

• Audio-focused specification — Part of the UFW series tailored for audio equipment, making selection straightforward for audio designers.
• Defined loss characteristics — Specified tan δ (0.20 at 16 V, 120 Hz) enables accurate estimation of dissipation and thermal behavior in audio power paths.
• High ripple capability — Clear ripple current ratings at both 120 Hz and 10 kHz allow designers to account for mains ripple and higher-frequency switching content.
• Long endurance at elevated temperature — 2000 hours at 85°C supports reliability targets for sustained operation in warm environments.
• Compact, standard radial form factor — Small φ8 can and common lead spacing simplify integration into established through-hole production workflows.
