UFW1H472MRD

The UFW1H472MRD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UFW series, specified for audio equipment applications. It provides 4.7 mF (4700 µF) capacitance at a 50 V rating with a polarized radial can package (φ20×40 mm) and 10 mm lead spacing.

Designed for duty in audio and power-smoothing roles, this part combines large capacitance, defined ripple performance across low and high frequencies, and a 2000-hour endurance at 85°C for predictable long-term behavior in embedded systems and audio circuits.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance at a 50 V rated voltage, suitable for bulk energy storage and smoothing in audio circuits.
• Tolerance & Polarization — ±20% capacitance tolerance at 120 Hz, 20°C; polarized construction for DC electrolytic applications.
• Loss Factor (tan δ) — Specified tan δ of 0.18 at 20°C, 120 Hz for the part to help assess dissipation and ESR-related behavior.
• Ripple Current Capability — 2.9 A rated ripple current at 120 Hz and 3.335 A at 10 kHz, with frequency coefficients (1000–10000 µF category) to scale ripple ratings across frequency: 0.85 (50 Hz), 1.00 (120 Hz), 1.10 (300 Hz), 1.13 (1 kHz), 1.15 (≥10 kHz).
• Leakage Current — Specified leakage current of 7050 µA, for design validation of standby and bias currents.
• Endurance & Temperature — 2000 hours at 85°C endurance rating; operating temperature range −40°C to +85°C for expected performance across typical environmental conditions.
• Mechanical & Packaging — φ20×40 mm can size with 10 mm lead spacing (±0.5 mm); shipped in bulk/no terminal forming or bag packing formats for assembly flexibility.

Typical Applications

• Audio Power Supply Filtering — Bulk energy storage and smoothing for amplifier power rails and audio supply decoupling.
• Power Smoothing in Consumer Electronics — DC link and smoothing capacitor where high capacitance and controlled ripple handling are required.
• Embedded System Power Rails — Large-value reservoir capacitor for boards requiring stable supply during transient loads.

Unique Advantages

• Large Capacitance in a Compact Can — 4700 µF in a φ20×40 mm radial can provides substantial bulk capacitance while keeping board area predictable.
• Defined Ripple Performance Across Frequency — Separate ripple current ratings for 120 Hz and 10 kHz plus frequency coefficients let engineers size capacitors for both mains-rectified and higher-frequency switching environments.
• Engineered Endurance — 2000-hour rating at 85°C supports lifetime planning and reliability assessments for audio and electronic equipment.
• Clear Mechanical Specification — Standard radial lead spacing (10 mm ±0.5 mm) and packaging options simplify PCB layout and procurement for through-hole assembly flows.
• Application-Focused Series — Part of Nichicon’s UFW series for audio equipment, allowing designers to align component selection with series-level characteristics.

Why Choose UFW1H472MRD?
