UKW0J471MED

The UKW0J471MED is a radial-lead aluminum electrolytic capacitor optimized for audio and AV equipment. It provides 470 µF capacitance at a rated voltage of 6.3 V in a compact φ6.3 × 11 mm can with 2.5 mm lead spacing.

Designed for reliability in audio circuits, the part delivers specified ripple handling at both low and high frequencies, a controlled loss tangent, and a 2000-hour endurance rating at 85°C—making it suitable for power decoupling, supply filtering, and coupling applications in consumer audio and AV devices.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a rated voltage of 6.3 V and ±20% tolerance for predictable bulk energy storage and decoupling.
• Audio-focused electrolyte: Part of the UKW series developed to realize a harmonious balance of sound quality; targeted for AV and audio equipment applications.
• Low- and high-frequency ripple handling: 310 mA ripple current at 120 Hz and 465 mA at 10 kHz to support both mains-frequency and higher-frequency switching or audio-related ripple currents.
• Loss characteristics: Specified tangent of loss angle (tan δ) of 0.28 at 20°C, 120 Hz, enabling designers to evaluate ESR-related dissipation in audio signal and power paths.
• Compact radial package: φ6.3 × 11 mm can with 2.5 mm lead spacing and radial lead mounting for easy insertion into through-hole PCBs and tight layouts.
• Reliability & lifetime: Endurance rating of 2000 hours at 85°C and operating temperature range of −40°C to +85°C for sustained performance in typical consumer AV environments.
• Leakage current: Specified leakage current of 88.83 µA to help estimate standby losses and bias requirements.
• RoHS compliant: Meets RoHS directive requirements for lead-free environmental compliance.

Typical Applications

• Audio equipment: Bulk filtering, decoupling and coupling in amplifiers, preamplifiers, and other AV circuits where audio quality and stable supply decoupling are important.
• Consumer AV devices: Power-supply smoothing and local energy storage in set-top boxes, receivers, and media players that require compact through-hole components.
• Signal coupling and decoupling: Use in audio signal paths and power rails to maintain low-frequency energy reserve and manage ripple in mixed-signal audio systems.

Unique Advantages

• Audio-tuned electrolyte: Series development emphasizes sound-quality balance, providing designers with a capacitor formulated for AV and audio performance objectives.
• Dual-frequency ripple capability: Published ripple ratings at both 120 Hz and 10 kHz allow accurate assessment for systems exposed to low-frequency mains ripple and higher-frequency switching noise.
• Compact footprint: Small φ6.3 × 11 mm can with 2.5 mm lead spacing enables implementation in space-constrained through-hole layouts without sacrificing capacitance.
• Predictable loss and leakage: Specified tan δ and leakage current values support thermal and bias budgeting during design and verification.
• Durability for consumer AV environments: 2000-hour endurance at 85°C and a −40°C to +85°C operating range provide stability across typical operating conditions.
• Regulatory compliance: RoHS compliance supports environmental requirements for contemporary consumer electronics.
