UFW1E471MPD

The UFW1E471MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UFW series, designed for audio equipment and related electronic applications. It provides 470 µF capacitance at a 25 V rating in a compact φ10 × 12.5 mm can with 5 mm lead spacing.

Engineered for reliable power smoothing and decoupling, this capacitor combines a 2000 h endurance at 85°C, low leakage, and specified ripple-current performance at both low and high frequencies to support audio power rails and signal circuits.

Key Features

• Capacitance & Tolerance — 470 µF nominal with ±20% tolerance, specified at 120 Hz and 20°C.
• Rated Voltage — 25 V DC rating suitable for a variety of low-voltage audio and power-supply applications.
• Radial Lead Package — φ10 × 12.5 mm can with 5 mm lead spacing for through-hole, radial-lead mounting in compact PCB layouts.
• Ripple Current Performance — Rated ripple current of 530 mA at 120 Hz and 795 mA at 10 kHz, supporting both low-frequency smoothing and higher-frequency decoupling.
• Low Leakage — Specified leakage current of 352.5 µA for minimized standby loss and stable bias behavior.
• Operational Temperature & Life — Operating range −40°C to +85°C with a rated life of 2000 hours at 85°C.
• Audio-focused Series — Part of the UFW family specified for audio equipment, reflecting design choices targeted at audio power and signal circuits.

Typical Applications

• Audio Amplifiers — Power-supply smoothing and decoupling on amplifier rails to support stable audio performance.
• Consumer Audio Electronics — Bulk filtering and reservoir capacitance in compact consumer devices where radial-lead mounting is preferred.
• Analog Power Rails — Decoupling and smoothing for analog circuitry that benefits from stable capacitance and low leakage over temperature.

Unique Advantages

• Balanced Ripple Capability — 530 mA at 120 Hz and 795 mA at 10 kHz provide measurable ripple handling across low and high frequency regimes.
• Compact, Through-Hole Form — φ10 × 12.5 mm radial can with 5 mm lead spacing fits space-constrained boards while remaining easy to assemble by hand or automated insertion.
• Long Endurance at Elevated Temperature — 2000 hours rated life at 85°C supports designs with sustained thermal stress.
• Wide Operating Temperature — −40°C to +85°C rating for use across varied environmental conditions encountered in consumer and professional audio gear.
• Low Standby Leakage — Specified leakage current of 352.5 µA helps preserve system idle current budgets and bias stability.
• Audio-Targeted Series — Part of Nichicon’s UFW series, which is specified for audio equipment applications.
