UKW0J222MPD

The UKW0J222MPD is a Nichicon UKW-series aluminum electrolytic capacitor designed for audio equipment. It is a miniature, radial-lead polarized can with 2.2 mF (2200 µF) capacitance at a 6.3 V rating, optimized for AV and audio applications where compact size and audio-focused electrolyte characteristics matter.

Key attributes include a low tanδ measured at 0.10 (20°C, 120 Hz), high ripple-current capability, and a rated endurance of 2000 hours at 85°C. RoHS compliant. Status: End Of Life.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20%.
• Audio-Optimized Electrolyte — UKW-series formulation targeting a harmonious balance of sound quality for AV and audio equipment.
• Low Loss — tanδ (DF) = 0.10 measured at 20°C, 120 Hz (at rated voltage), supporting low dissipation in audio signal and power circuits.
• High Ripple-Current Handling — Low-frequency ripple current 980 mA at 120 Hz and high-frequency ripple current 1.127 A at 10 kHz, enabling effective power-supply smoothing and decoupling.
• Leakage Current — Specified leakage current 415.8 µA.
• Endurance & Temperature Range — Rated for 2000 hours at 85°C, operating across −40°C to +85°C.
• Compact Radial Can — Dimensions φ10×20 mm with 5 mm lead spacing (±0.5 mm); radial lead mounting for through-hole designs. Packaging: Bulk (no terminal forming) or bag packing.
• Compliance — RoHS compliant.

Typical Applications

• Audio Amplifiers — Bulk decoupling and power-supply smoothing in amplifier modules where compact, audio-optimized capacitors are required.
• AV Equipment — Power filtering and energy reservoir duties in consumer AV devices that benefit from the UKW-series electrolyte characteristics.
• Preamp and Signal Conditioning — Use in DC blocking or coupling applications within audio signal paths that require low dissipation and stable performance.

Unique Advantages

• Audio-focused formulation: The UKW-series electrolyte is developed to realize a harmonious balance of sound quality, making this part suitable for AV and audio use.
• High ripple tolerance: Rated ripple currents of 980 mA (120 Hz) and 1.127 A (10 kHz) allow reliable smoothing under typical audio power conditions.
• Compact footprint: φ10×20 mm radial can with 5 mm lead spacing enables space-efficient through-hole layouts.
• Low dissipation: tanδ = 0.10 at 20°C/120 Hz reduces loss in audio and power circuits, supporting cleaner performance.
• Robust operating window: −40°C to +85°C operating range and 2000 h endurance at 85°C provide predictable life characteristics for AV product designs.
• Regulatory compliance: RoHS compliant for markets requiring restricted-substance adherence.
