UKW2A471MHD

The UKW2A471MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKW series, designed for audio and AV equipment. It combines high capacitance (470 µF) and 100 V voltage rating with an audio-focused electrolyte formulation aimed at delivering a harmonious balance of sound quality for professional and consumer audio systems.

Engineered for through-hole mounting, this φ16×25 mm can with 7.5 mm lead spacing provides robust ripple handling and a 2000-hour endurance rating at 85°C for reliable operation in demanding audio environments.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 100 V for high energy storage in audio power stages and AV systems.
• Audio-Optimized Electrolyte — UKW series formulation targeted at realizing a harmonious balance of sound quality for AV and audio equipment.
• Low Loss (tan δ) — tanδ = 0.08 (max) measured at 20°C, 120 Hz, supporting low dissipation in signal-related power rails.
• Ripple Current Capability — 1000 mA at 120 Hz (low frequency) and 1500 mA at 10 kHz (high frequency), with frequency coefficients for 100–470 µF of 1.00 at 120 Hz and 1.50 at 10 kHz.
• Leakage Current — Specified leakage current of 1410 µA at rated conditions.
• Endurance — 2000 hours at 85°C, meeting endurance criteria after high-temperature voltage application and recovery to 20°C.
• Operating Temperature — −40°C to +85°C for broad environmental compatibility in consumer and professional audio installations.
• Package & Mounting — Radial lead, φ16×25 mm can, 7.5 mm lead spacing; supplied in bulk (no terminal forming) / bag packing for production assembly.
• Environmental Compliance — RoHS compliant per provided product classification.

Typical Applications

• Audio and AV Equipment — Suited for use in audio systems where the UKW series' electrolyte and electrical characteristics support improved tonal balance and performance.
• Power Supply Smoothing for Audio Electronics — Provides bulk energy storage and ripple handling in audio power rails within the specified ripple current limits.
• High-Voltage Audio Modules — 100 V rating enables use in higher-voltage sections of amplifiers and AV components where elevated DC headroom is required.

Unique Advantages

• Audio-Focused Formulation — Electrolyte developed to realize a harmonious balance of sound quality, making the part appropriate for AV and audio-centric designs.
• High Voltage Capability — 100 V rating gives designers additional voltage margin for higher-headroom circuits without changing capacitor topology.
• Broad Ripple Handling — Specified ripple currents at both 120 Hz and 10 kHz (with corresponding frequency coefficients) support performance across low and high-frequency ripple spectra.
• Proven Endurance — 2000-hour rated life at 85°C provides predictable ageing characteristics for longer-term reliability in equipment operating near elevated temperatures.
• Through-Hole Robustness — Radial lead, can-style package with standard 7.5 mm lead spacing simplifies mechanical mounting and replacement in legacy and modern boards.
• Regulatory Compliance — Supplied RoHS-compliant to align with modern environmental requirements.
