UKW1H470MED

The UKW1H470MED is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKW series, specified at 47 µF and 50 V. Designed for audio and AV equipment, the UKW series emphasizes sound-quality performance enabled by a specially formulated electrolyte.

This compact, polarized capacitor is intended for through-hole applications where low loss, measured ripple capability, and a small footprint (φ6.3×11L / L: 1.1 × D: 0.63 cm) are required. It is RoHS compliant and packaged for bulk or bag handling.

Key Features

• Electrical performance — 47 µF capacitance at a 50 V rating with capacitance tolerance of −20% to +20% and measured tanδ of 0.12 (20°C, 120 Hz).
• Ripple handling — Low-frequency ripple current 150 mA (120 Hz) and high-frequency ripple current 300 mA (10 kHz) to support power smoothing in audio circuits.
• Leakage current — Specified leakage current of 70.5 µA for predictable bias behavior after voltage application.
• Reliability and endurance — Rated for 2000 hours at 85°C, meeting endurance criteria after restoration to 20°C.
• Package and mounting — Radial lead (polar) construction with 2.5 mm lead spacing (±0.5 mm tolerance) for through-hole PCBs; case form φ6.3×11L.
• Operating range — Specified to operate between −40°C and 85°C, suitable for typical consumer audio environments.
• RoHS compliant — Conforms to the RoHS directive as indicated in product documentation.

Typical Applications

• Audio and AV equipment — Power supply filtering and decoupling where audio-focused electrolytic behavior contributes to signal integrity.
• Through-hole consumer electronics — Compact radial-lead fit for small PCB real estate in consumer audio subassemblies and modules.
• Power smoothing for audio circuits — Provides bulk capacitance and ripple handling for local supply stabilization in preamplifiers, tone stages, and related circuitry.

Unique Advantages

• Audio-oriented electrolyte formulation — The UKW series development focuses on a balance of sound quality, aligning capacitor behavior with AV and audio designs.
• Low loss at rated conditions — tanδ of 0.12 (20°C, 120 Hz) supports efficient energy transfer and reduced heat generation in constrained assemblies.
• Measured ripple capacity across frequencies — Defined ripple current ratings at both low and high frequencies (150 mA at 120 Hz; 300 mA at 10 kHz) allow designers to size decoupling for real operating conditions.
• Compact radial package — φ6.3×11L size with standard 2.5 mm lead spacing simplifies placement in dense through-hole layouts.
• Endurance for sustained operation — 2000 hours at 85°C endurance rating provides a defined qualification point for lifecycle planning.
• Regulatory compliance — RoHS compliance supports environmental and regulatory requirements for modern electronics manufacturing.
