UKW1A472MHD

The UKW1A472MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UKW series, optimized for audio and AV equipment. It delivers 4700 µF capacitance at a 10 V rating in a compact φ12.5×25 mm can with 5 mm lead spacing, offering high ripple capability and long-term operation for power supply and signal support in audio systems.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance at a 10 V rated voltage with ±20% tolerance, suitable for bulk energy storage and smoothing in low-voltage audio rails.
• High Ripple Current — Rated ripple current of 1.8 A at 120 Hz (low frequency) and 2.07 A at 10 kHz (high frequency), enabling reliable performance under AC load conditions common in audio power supplies.
• Loss and Leakage — Specified tangent of loss angle (tanδ) of 0.3 and leakage current of 1410 µA as provided for this part, supporting predictable behavior in circuit designs.
• Lifetime & Temperature Range — Rated for 2000 hours at 85 °C and operable from −40 °C to 85 °C, allowing use across a wide ambient range in consumer AV environments.
• Compact Radial Package — φ12.5×25 mm can with 5 mm lead spacing (radial lead mounting) for straightforward through-hole implementation and replacement-friendly serviceability.
• RoHS Compliant & Series Heritage — RoHS-compliant construction and part of the UKW series designed for audio applications, incorporating Nichicon’s formulated electrolyte intended for sound-quality balance.
• Production & Packaging — Provided in bulk/bag packaging and listed as mass production status for supply continuity and BOM planning.
• Readability — Marked with gold-colored print on a black sleeve for clear polarity and identification on assembly.

Typical Applications

• Audio and AV Power Rails — Bulk smoothing and energy storage on low-voltage amplifier and preamplifier supplies to support stable audio playback.
• Consumer AV Equipment — Power supply filtering and decoupling in receivers, integrated amplifiers, and media players where compact, high-capacitance radial components are required.
• Signal and Coupling Circuits — Use where large capacitance and stable leakage/ripple characteristics contribute to consistent audio performance.

Unique Advantages

• High ripple handling for audio power stages: Specified 1.8 A (120 Hz) and 2.07 A (10 kHz) ripple ratings reduce stress on power rails in dynamic audio loads.
• Large capacitance in a compact can: 4700 µF in a φ12.5×25 mm package minimizes board footprint while providing substantial bulk charge storage.
• Designed for audio performance: Part of the UKW series with electrolyte development aimed at a harmonious balance of sound quality for AV applications.
• Long life at elevated temperature: 2000 hours at 85 °C supports durability in equipment that operates in warm enclosures.
• Clear polarity and production readiness: Gold print on black sleeve improves assembly accuracy; bulk/bag packaging and mass production status aid procurement and manufacturing planning.
