UFW1J472MRD

The UFW1J472MRD is a Nichicon UFW series aluminum electrolytic capacitor in a radial-lead can package, specified for audio equipment. It provides 4700 µF capacitance at a 63 V rating with polarized radial leads for through-hole mounting.

Designed for applications that require high bulk capacitance and robust ripple handling, this part delivers 3.4 A low-frequency ripple current (120 Hz) and 3.91 A high-frequency ripple current (10 kHz) with a rated endurance of 2000 hours at 85°C and an operating temperature range of −40°C to +85°C.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, providing substantial energy storage for power rail smoothing and decoupling.
• High Ripple Current Capability — 3.4 A at 120 Hz and 3.91 A at 10 kHz frequency ratings allow the capacitor to handle significant AC ripple in audio power circuitry.
• Endurance & Temperature Range — Rated for 2000 hours at 85°C and specified to operate from −40°C to +85°C, supporting long-life performance in thermal environments within that range.
• Leakage & Loss Characteristics — Specified leakage current of 8883 µA and manufacturer tolerance on tan δ consistent with the UFW series' audio-oriented specifications.
• Package & Mounting — Radial lead, can-style package (φ22 × 50 mm) with 10 mm lead spacing for straightforward through-hole assembly and mechanical stability.
• Audio-Focused Series — Part of Nichicon’s UFW series, which is specified for use in audio equipment.

Typical Applications

• Audio equipment — Intended for use in audio systems where large capacitance and rated ripple current support power supply smoothing and stable operation of amplifiers and audio circuits.

Unique Advantages
