Designed for audio-focused applications, the UKW series incorporates a specifically developed electrolyte to support audio performance while offering defined endurance and electrical characteristics for embedded designs. Status: End Of Life.

Key Features

• Audio‑oriented design — Part of Nichicon’s UKW series developed to realize a harmonious balance of sound quality through a tailored electrolyte.
• Electrical characteristics — 100 µF capacitance at 25 V with ±20% tolerance and a specified tanδ of 0.16 (at 20 °C, 120 Hz) for predictable AC characteristics.
• Ripple performance — Rated for 185 mA low‑frequency ripple current (120 Hz) and 277.5 mA high‑frequency ripple current (10 kHz), supporting typical audio power supply demands.
• Low leakage current — Specified leakage current of 75 µA to help maintain stable bias conditions over time.
• Endurance — 2000 hours life at 85 °C with defined post‑test limits for capacitance, tanδ and leakage current.
• Compact radial package — φ6.3×11 mm can, radial lead mounting with 2.5 mm lead spacing; supplied bulk/bag packing (no terminal forming).
• Operating temperature range — –40 °C to 85 °C for compatibility with a wide range of audio and AV equipment environments.
• RoHS compliant — Conforms to RoHS directive requirements.

Typical Applications

• Audio equipment — Intended use in audio and AV designs where capacitor characteristics contribute to audible performance and system behavior.
• AV electronics — Suited to consumer and professional AV modules that require compact electrolytic capacitance with defined ripple and leakage specs.
• Power filtering in audio modules — Compact radial can form factor fits tight layouts while providing specified ripple handling and endurance for audio power rails.

Unique Advantages

• Electrolyte tuned for sound: UKW series development emphasizes sound quality, giving designers a capacitor choice that aligns with audio performance goals.
• Measured AC loss characteristics: Specified tanδ (0.16 at 20 °C/120 Hz) provides predictable dissipation behavior for audio circuit designers.
• Defined ripple handling across frequencies: Separate low‑ and high‑frequency ripple ratings (185 mA @120 Hz, 277.5 mA @10 kHz) help match the capacitor to real‑world audio power conditions.
• Compact footprint: φ6.3×11 mm radial can with 2.5 mm lead spacing enables denser PCB layouts without sacrificing essential capacitance.
• Long‑term endurance data: 2000 hour life at 85 °C with post‑test limits gives clear expectations for reliability in deployed systems.
• Regulatory compliance: RoHS status documented for straightforward inclusion in compliant assemblies.
