UKW1C471MPD

The UKW1C471MPD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UKW series, specified at 470 µF and 16 V. It is designed for audio and AV equipment where a balance of sound quality and reliable power filtering is required.

Built around Nichicon’s UKW series chemistry, the part emphasizes audio performance through series-specific electrolyte development while delivering measurable electrical characteristics for power smoothing and decoupling in audio circuits.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 16 V rating and ±20% tolerance, suitable for typical audio filtering and decoupling tasks.
• Audio-focused Electrolyte — Part of the UKW series developed for a harmonious balance of sound quality, targeted at AV and audio equipment applications.
• Loss Angle (tan δ) — tanδ = 0.20 measured at 20°C and 120 Hz, providing a defined dissipation factor for predictable AC behavior.
• Ripple Current Capability — Handles 420 mA at 120 Hz (low frequency) and 630 mA at 10 kHz (high frequency), supporting both power-supply smoothing and higher-frequency audio circuitry demands.
• Leakage Current — Specified leakage current of 225.6 µA, aiding designers in budgeting quiescent currents for bias and coupling networks.
• Temperature & Endurance — Rated for operation from −40°C to +85°C with 2000 hours endurance at 85°C, enabling sustained performance under elevated-temperature conditions.
• Form Factor & Mounting — Compact radial can, size φ8 × 11.5 mm (L: 11.5 mm × D: 8.0 mm), 3.5 mm lead spacing (±0.5 mm), supplied as bulk (no terminal forming) or bag packed.
• Compliance & Availability — RoHS compliant and listed as in mass production by the manufacturer Nichicon.

Typical Applications

• Audio Equipment — Power supply smoothing, decoupling and coupling in amplifiers and preamplifiers where controlled leakage and dissipation are important for signal integrity.
• AV Systems — Bulk and decoupling capacitance in consumer and professional AV devices, leveraging the UKW series’ audio-oriented electrolyte.
• Power Filtering in Signal Chains — Local supply filtering for audio front-ends and driver stages where compact radial mounting is required.

Unique Advantages

• Audio-optimized chemistry: Series-level electrolyte development aims to deliver a harmonious balance of sound quality appropriate for AV and audio equipment.
• Measurable AC performance: Defined tanδ at 20°C/120 Hz and specified ripple currents at both low and high frequencies allow accurate design margins for filtering and decoupling.
• Compact radial can: Small φ8 × 11.5 mm dimensions and 3.5 mm lead spacing suit space-constrained PCB layouts and through-hole assembly.
• Extended endurance: 2000 hours at 85°C specification supports reliability in elevated-temperature environments common in audio electronics.
• Production-ready supply: Mass-production status and RoHS compliance simplify sourcing and regulatory compliance for volume designs.
• Packaging options: Available in bulk (no terminal forming) or bag packing to match assembly and procurement preferences.
