UKW1V471MPD

The UKW1V471MPD is a Nichicon UKW-series radial aluminum electrolytic capacitor designed for audio and AV equipment. It delivers a 470 µF capacitance at a 35 V rating in a compact φ10 × 16L can with radial leads and 5 mm lead spacing.

Engineered for audio applications, this part combines a low dissipation factor, substantial ripple-current capability, and a rated 2000-hour endurance at 85°C to support power filtering and decoupling in compact audio circuits.

Key Features

• Electrical performance — 470 µF capacitance at 35 V with ±20% tolerance; low tangent of loss angle (tanδ) of 0.14 measured at 20°C and 120 Hz for stable AC performance.
• High ripple-current capability — Rated ripple current of 630 mA at 120 Hz (low frequency) and 945 mA at 10 kHz (high frequency) to handle dynamic loads in audio power stages.
• Leakage and polarization — Polarized aluminum electrolytic design with specified leakage current of 493.5 µA under rated conditions.
• Reliability and endurance — Rated for 2000 hours at 85°C (endurance), with operating temperature range from −40°C to +85°C for extended field use.
• Compact radial package — φ10 × 16L can, lead spacing 5 mm ±0.5 mm, radial lead mounting for through-hole PCB designs; supplied in bulk/bag packing (no terminal forming).
• Audio-focused development — Part of the UKW series developed for audio/AV equipment, emphasizing a balance in sound quality through a specialized electrolyte.
• RoHS compliant and production-ready — RoHS status compliant and listed as mass production.

Typical Applications

• Audio amplifiers — Power supply smoothing and decoupling in amplifier and preamplifier circuits where stable low-frequency performance and ripple handling are required.
• AV equipment — Supply filtering and energy storage in consumer AV systems designed around compact radial electrolytic components.
• Audio power supplies — Bulk decoupling and ripple suppression in regulated and unregulated audio power rails operating up to 35 V.

Unique Advantages

• Audio-oriented electrolyte development — Designed within the UKW series to support a harmonious balance of sound quality for AV and audio equipment.
• Low loss for clearer signal handling — Tanδ of 0.14 at 20°C/120 Hz reduces dissipation in AC conditions relevant to audio circuits.
• Robust ripple-current ratings — 630 mA (120 Hz) and 945 mA (10 kHz) ratings support dynamic current demands in audio power stages and decoupling roles.
• Long endurance at elevated temperature — 2000 hours at 85°C provides predictable aging characteristics for designs exposed to higher operating temperatures.
• Compact radial form factor — φ10 × 16L can and standard 5 mm lead spacing enable space-efficient through-hole layouts and easy manual or wave assembly.
• Mass-production availability — RoHS-compliant and produced in volume, suitable for production runs and replacement sourcing.
