UKW1C472MHD

The UKW1C472MHD is a Nichicon UKW series aluminum electrolytic capacitor specified for audio and AV equipment. It provides high bulk capacitance (4.7 mF / 4700 µF) in a compact radial-can package, optimized where sound-quality-focused power filtering and energy storage are required.

Key hardware characteristics include a 16 V rated voltage, radial lead mounting, robust ripple-handling capability, and a defined endurance of 2000 hours at 85°C—together offering a reliable option for audio power rails and related circuitry.

Key Features

• Capacitance & Voltage: 4.7 mF (4700 µF) rated at 16 V—delivers substantial bulk energy storage for supply smoothing and decoupling in audio systems.
• High Ripple Capacity: Low-frequency ripple current 2.1 A (120 Hz) and high-frequency ripple current 2.415 A (10 kHz) support demanding power-rail conditions across audio bandwidths.
• Acoustic-optimized Electrolyte: Part of the UKW series developed for audio equipment to support a harmonious balance of sound quality, as specified by the series documentation.
• Electrical Loss & Leakage: Specified tangent of loss angle (tan δ) 0.26 measured at 20°C, 120 Hz, and measured leakage current of 2256 µA—provides clear, verifiable electrical parameters for design validation.
• Thermal & Endurance: Rated operating range −40°C to +85°C with endurance specified as 2000 hours at 85°C under rated voltage conditions.
• Package & Mechanical: Radial lead can, size φ16 × 25 mm (L), lead spacing 7.5 mm (±0.5 mm), available in Bulk (No Terminal Forming) or Bag packing for production flexibility.
• Regulatory: RoHS compliant as specified in the product information.

Typical Applications

• Audio and AV Equipment: Bulk energy storage and smoothing in audio power supplies where the UKW series is specified for sound-quality-sensitive designs.
• Power Supply Filtering: Smoothing and decoupling on 16 V rails where higher capacitance and specified ripple current ratings are required.
• Consumer and Professional Audio Electronics: Use in amplifiers, preamplifiers, and AV subsystems that benefit from the UKW series’ audio-focused formulation and endurance.

Unique Advantages

• High Bulk Capacitance in a Compact Can: 4700 µF in a φ16 × 25 mm package enables substantial energy storage without a large PCB footprint.
• Measured Ripple Ratings for Design Confidence: Explicit low- and high-frequency ripple current specifications (2.1 A at 120 Hz, 2.415 A at 10 kHz) let engineers size capacitors based on real operating conditions.
• Audio-Focused Electrolyte Development: Part of a series developed to balance sound quality—useful when audio performance is a design priority.
• Defined Endurance and Temperature Window: 2000 hours at 85°C rating and −40°C to +85°C operating range provide predictable lifecycle behavior in specified environments.
• Production-Ready Packaging: Available in bulk or bag packing to suit assembly and stocking workflows.
• RoHS Compliance: Meets RoHS requirements as documented for regulatory alignment in commercial products.
