UKW1H471MHD

The UKW1H471MHD is a Nichicon UKW series aluminum electrolytic capacitor specified at 470 µF and 50 V in a radial lead can. It combines a compact φ12.5 × 20 mm case with a polarized radial-lead package and is optimized for audio and AV equipment where stable bulk capacitance and ripple handling are required.

Designed for use across -40°C to 85°C and produced to a 2000-hour endurance at 85°C, this component targets designers seeking a reliable, production-ready electrolytic solution with defined ripple, leakage and dissipation characteristics.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance for bulk energy storage and decoupling.
• Radial Lead Can — φ12.5 × 20 mm aluminum can with 5 mm lead spacing (±0.5 mm) for through-hole mounting and easy PCB placement.
• Audio-Targeted Chemistry — Part of the UKW series developed for audio/AV applications, leveraging Nichicon’s electrolyte formulation for application-specific performance.
• Dissipation Factor — tanδ of 0.12 measured at 20°C, 120 Hz (rated voltage), suitable for predictable AC loss behavior in audio circuits.
• Ripple Current Capability — Low-frequency ripple current of 760 mA at 120 Hz and high-frequency ripple current of 1.14 A at 10 kHz to support filtering and supply smoothing across audio bandwidths.
• Leakage & Endurance — Specified leakage current of 705 µA and rated for 2000 hours at 85°C for long-term stability under rated conditions.
• Environmental Compliance & Packaging — RoHS compliant; available in Bulk (No Terminal Forming) or Bag Packing. Product status: Mass Production.

Typical Applications

• Audio Equipment — Bulk filtering and power smoothing in amplifiers, preamplifiers and other audio signal chain power stages.
• AV Systems — Energy storage and decoupling in consumer and professional audio-visual equipment where reliable ripple handling and stable capacitance are needed.
• Power Supply Filtering — Local reservoir and smoothing capacitor in DC supply rails within audio and AV electronics.

Unique Advantages

• High Bulk Capacitance at 50 V — 470 µF/50 V delivers substantial energy storage for smoothing and transient support in medium-voltage audio rails.
• Measured Dissipation Factor — tanδ 0.12 (120 Hz, 20°C) provides predictable AC loss characteristics for designers balancing noise and thermal budgets.
• Defined Ripple Performance — Rated ripple currents of 760 mA (120 Hz) and 1.14 A (10 kHz) let engineers size capacitors for both low- and high-frequency ripple conditions.
• Temperature & Endurance Specification — Rated for operation from -40°C to 85°C with 2000 hours endurance at 85°C, supporting designs with defined lifetime expectations.
• Board-Friendly Form Factor — Compact φ12.5 × 20 mm radial can with 5 mm lead spacing simplifies layout for through-hole assemblies.
• Production-Ready & Compliant — RoHS compliant and listed as Mass Production, enabling straightforward procurement and assembly planning.
