UKW1E471MPD

The UKW1E471MPD is a Nichicon UKW-series aluminum electrolytic capacitor in a radial-lead can, rated 470 µF at 25 V with ±20% tolerance. It is part of the UKW family specifically developed for audio equipment and AV applications, incorporating a newly developed electrolyte to support a harmonious balance of sound quality.

Engineered for compact audio designs, this polarized capacitor offers a low dissipation factor (tanδ 0.16 at 20°C, 120 Hz), measurable ripple-current capability (530 mA at 120 Hz and 795 mA at 10 kHz), a -40°C to 85°C operating range, and 2000 hours endurance at 85°C. It is RoHS compliant and available in bulk or bag packing for production use.

Key Features

• Audio-Optimized Electrolyte — Developed electrolyte in the UKW series enables a harmonious balance of sound quality suitable for audio and AV equipment.
• Nominal Capacitance & Voltage — 470 µF capacitance at a 25 V rating with ±20% tolerance for consistent decoupling and energy storage needs in audio applications.
• Low Dissipation Factor — tanδ 0.16 measured at 20°C and 120 Hz, supporting low-loss performance in signal-relevant circuits.
• Ripple-Current Capability — Rated low-frequency ripple current of 530 mA at 120 Hz and high-frequency ripple current of 795 mA at 10 kHz to handle dynamic loads.
• Endurance & Temperature Range — Lifetime of 2000 hours at 85°C and an operating temperature range of -40°C to +85°C for sustained performance.
• Compact Radial Can — Small footprint with dimensions φ10 × 12.5 mm and 5 mm lead spacing, suitable for tight board layouts.
• Polarized Radial Lead Package — Standard radial lead construction (polarized) for through-hole mounting and straightforward assembly.
• Environmental Compliance & Packaging — RoHS compliant and supplied in bulk (no terminal forming) or bag packing; part is in mass production.

Typical Applications

• AV Equipment — Designed for use in audio- and AV-focused designs where the UKW series’ audio-oriented characteristics are preferred.
• Audio Systems — Applicable across audio equipment that specifies a 470 µF, 25 V polarized electrolytic capacitor from the UKW series.
• Replacement and Service Parts for Audio Gear — Suitable as a direct-use component in repair or refurbishment of audio and AV products within the specified electrical and mechanical constraints.

Unique Advantages

• Audio-focused formulation: The UKW-series electrolyte was developed to achieve a harmonious balance of sound quality for audio applications.
• Measured low-loss performance: tanδ of 0.16 at 25 V, 120 Hz, 20°C provides predictable dissipation characteristics for audio circuits.
• Defined ripple handling: Explicit ripple-current ratings—530 mA (120 Hz) and 795 mA (10 kHz)—support designs with varying ripple-frequency content.
• Durability under stress: 2000-hour endurance at 85°C ensures component stability for extended operation in hot environments.
• Compact, serviceable package: φ10 × 12.5 mm radial can with 5 mm lead spacing offers a small board footprint while retaining through-hole robustness.
• Regulatory compliance: RoHS compliant construction aligns with current environmental requirements.
