UKW0J472MHD

The UKW0J472MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKW series, optimized for audio and AV equipment. It provides 4.7 mF (4700 µF) capacitance at a 6.3 V rating in a compact φ12.5 × 20 mm can suitable for through-hole assemblies.

Designed for applications that require bulk energy storage and ripple handling in low-voltage audio circuits, this component delivers a specified lifetime of 2000 hours at 85°C and is RoHS compliant.

Key Features

• High Capacitance (Power): 4700 µF (4.7 mF) capacitance provides substantial bulk energy storage for low-voltage audio circuitry.
• Low-Voltage Rating: Rated voltage of 6.3 V for applications that operate at low supply voltages.
• Audio-Optimized Chemistry: Part of the UKW series noted for electrolyte formulation aimed at audio/AV performance.
• Ripple Performance: Low-frequency ripple current 1.35 A (120 Hz) and high-frequency ripple current 1.552 A (10 kHz) to support smoothing and decoupling across audible and higher-frequency domains.
• Electrical Loss and Leakage: Tangent of loss angle (tanδ) 0.34 at 20°C, 120 Hz and measured leakage current 888.3 µA.
• Durability: Endurance rating of 2000 hours at 85°C; operating temperature range −40°C to +85°C.
• Package and Mounting: Radial lead, polarized aluminum can with 5 mm lead spacing (±0.5 mm) and compact physical size (φ12.5 × 20 mm / L: 2 cm × D: 1.25 cm).
• Compliance & Packaging: RoHS compliant; available in bulk (no terminal forming) or bag packing.

Typical Applications

• Audio Equipment: Bulk energy storage and power-supply smoothing in consumer and professional audio electronics where 6.3 V circuits are used.
• AV Equipment: Power decoupling and ripple suppression in AV components benefiting from the UKW series electrolyte characteristics.
• Through-Hole PCB Designs: Compact radial-lead can suitable for designers requiring a high-capacitance through-hole capacitor with 5 mm lead spacing.

Unique Advantages

• Large Capacitance in a Small Can: 4700 µF packaged in a φ12.5 × 20 mm case enables significant bulk capacitance where PCB space is limited.
• Measured Ripple Capacity: Specified low- and high-frequency ripple currents (1.35 A at 120 Hz; 1.552 A at 10 kHz) provide quantifiable performance for filtering and decoupling design decisions.
• Audio-Focused Formulation: UKW series electrolyte development targets balanced sound characteristics for audio/AV applications.
• Wide Operating Temperature Range: −40°C to +85°C supports a variety of environmental conditions common in consumer and professional audio systems.
• Defined Endurance: 2000 hours at 85°C gives a clear baseline for expected life under elevated temperature stress.
• Regulatory Compliance: RoHS compliance simplifies environmental and regulatory considerations for product designs.
