UFW1C472MHD

The UFW1C472MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series, designed for audio equipment applications. It delivers 4700 µF of capacitance at a 16 V rating in a compact φ16×25 mm can, combining high capacitance with through‑hole mounting convenience.

Key performance attributes include a wide operating temperature range (−40 °C to 85 °C), specified ripple current values at both low and high frequencies, and a 2000‑hour endurance rating at 85 °C—features that support reliable power filtering in audio designs.

Key Features

• Capacitance & Voltage: 4.7 mF (4700 µF) nominal capacitance with a rated voltage of 16 V and tolerance ±20% (120 Hz, 20 °C).
• Ripple Current Performance: Rated ripple current of 2.1 A at 120 Hz and 2.415 A at 10 kHz to support both low‑frequency power supply filtering and higher‑frequency ripple conditions.
• Leakage Current: Specified leakage current of 2256 µA, suitable for monitoring and budgeting standby currents in power circuits.
• Thermal & Endurance Rating: Operating temperature −40 °C to 85 °C with an endurance of 2000 hours at 85 °C under rated voltage.
• Mechanical & Mounting: Radial lead can package, size φ16×25 mm (D×L) with 7.5 mm lead spacing (±0.5 mm) for straightforward through‑hole assembly.
• Polarized Electrolytic Construction: Polar type suitable for DC power applications commonly found in audio circuitry.
• Marking & Packaging: Marked with black lettering on a gold sleeve; available in bulk (no terminal forming) or bag packing. Status: Mass production.

Typical Applications

• Audio Power Supplies — Bulk capacitance and rated ripple current make this capacitor well suited for smoothing and decoupling in audio power rails.
• Audio Amplifiers & Active Speakers — Provides reservoir capacitance to support dynamic current demands and reduce power‑rail ripple in amplifier stages.
• Mixing Consoles & Signal Processing Equipment — Used where stable supply filtering and long endurance at elevated temperatures are required.

Unique Advantages

• High Capacitance in a Compact Can: 4700 µF in a φ16×25 mm package provides substantial energy storage while minimizing board area for through‑hole designs.
• Dual‑Frequency Ripple Handling: Rated ripple current specified at both 120 Hz (2.1 A) and 10 kHz (2.415 A), enabling predictable performance across common audio power and switching noise frequencies.
• Robust Thermal Endurance: 2000 hours at 85 °C endurance rating supports long‑term operation in thermally demanding audio equipment environments.
• Wide Operating Temperature: −40 °C to 85 °C range accommodates both consumer and professional audio installations exposed to temperature variation.
• Through‑Hole Mounting Convenience: Radial lead format with 7.5 mm spacing simplifies assembly and repair on conventional PCBs.
• Production Availability: Mass production status and multiple packing options (bulk or bag) aid procurement and manufacturing planning.
