UFW1E472MHD

The UFW1E472MHD is a radial-lead aluminum electrolytic capacitor configured for audio equipment applications. It provides a high 4.7 mF capacitance at a 25 V rating in a compact φ16 × 30.5 mm can with 7.5 mm lead spacing.

Designed for bulk energy storage and power-rail smoothing, this polarized capacitor delivers specified ripple handling, controlled loss (tan δ), and a 2000-hour endurance at 85°C for reliable operation in consumer and professional audio systems.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) rated at 25 V, suitable for bulk filtering and smoothing on audio power rails.
• High Ripple Handling — 2.36 A ripple current at 120 Hz and 2.714 A at 10 kHz, enabling effective filtering under both low- and high-frequency ripple conditions.
• Loss and Leakage — Specified loss tangent of 0.22 and leakage current of 3525 µA, providing predictable dissipation and leakage characteristics for design margining.
• Reliability / Lifetime — Rated for 2000 hours at 85°C with endurance performance defined by the series specifications.
• Operating Range — Functionality from −40°C to +85°C to accommodate a wide range of ambient conditions encountered in audio equipment.
• Package & Mounting — Radial-lead can, φ16 × 30.5 mm body with 7.5 mm lead spacing (seated height 30.5 mm), supplied in bulk/bag packing for production assembly.
• Polarized Design — Polarized aluminum electrolytic construction for use where electrolytic polarity is required.

Typical Applications

• Audio Power Supplies — Bulk energy storage and smoothing on amplifier and preamplifier power rails to reduce low-frequency ripple and support transient currents.
• Amplifier Decoupling — Local reservoir capacitor for power-stage decoupling to help maintain stable supply voltage during dynamic audio signals.
• Consumer & Pro Audio Equipment — General-purpose electrolytic for mixers, receivers, and powered speakers where high capacitance and ripple capability are required.

Unique Advantages

• Substantial Energy Density: 4700 µF at 25 V provides significant bulk capacitance in a compact φ16 can, reducing the number of parts required for reservoir functions.
• Dual-Frequency Ripple Performance: Rated ripple currents specified at 120 Hz and 10 kHz let designers size capacitors for both mains-rectified and higher-frequency switching or audio-related ripple.
• Predictable Loss and Leakage: Specified tan δ and leakage current values allow accurate thermal and standby current budgeting in system-level power designs.
• Designed for Long-Term Operation: 2000 hours at 85°C endurance provides a defined reliability baseline for commercial audio equipment lifecycles.
• Compact Radial Form Factor: Standard radial lead spacing and can package simplify PCB layout and replacement in through-hole assemblies.
