UKW1V472MHD

The UKW1V472MHD is a radial-lead aluminum electrolytic capacitor designed for audio and AV equipment. It provides high capacitance (4.7 mF / 4700 µF) at a 35 V rating in a compact φ18 × 35.5 mm can with 7.5 mm lead spacing.

Built for power-filtering and energy-storage roles in audio circuits, this capacitor combines long-term endurance (2000 hours at 85°C), controlled dissipation (tan δ 0.2), and measurable ripple-handling performance to support stable analog and power-supply behavior in AV designs.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) rated at 35 V with ±20% tolerance for bulk energy storage and supply decoupling.
• Low Loss (tan δ) — Specified tan δ of 0.2 for reduced dissipation in audio signal and power paths.
• Endurance — Rated lifetime of 2000 hours at 85°C; capacitance change within ±20% and leakage current within initial specification after endurance testing.
• Ripple Current Capability — Rated ripple current 2.49 A at 120 Hz and 2.864 A at 10 kHz to handle power-supply ripple in audio applications.
• Temperature Range — Operates from −40°C to +85°C, suitable for a wide range of consumer and professional AV environments.
• Leakage Characteristics — Leakage current defined per datasheet: ≤0.03 CV (µA) after 1 minute and ≤0.01 CV (µA) after 2 minutes at 20°C.
• Package & Mounting — Radial lead, can-style package: φ18 × 35.5 mm (3.55 × 1.8 cm), 7.5 mm lead spacing for through-hole PCB mounting.
• RoHS Compliance — Component is RoHS compliant.

Typical Applications

• Audio and AV equipment — Bulk energy storage and smoothing for consumer and professional audio systems where stable supply rails improve performance.
• Amplifiers and receivers — Power-supply decoupling and reservoir capacitance in amplifiers, AV receivers, and related signal-chain electronics.
• Audio power modules — Filtering and ripple reduction in power modules and supply stages used in audio devices.

Unique Advantages

• High-capacitance energy reserve — 4700 µF provides substantial stored energy for supply smoothing and transient handling in audio power rails.
• Audio-focused electrical characteristics — Specified low dissipation (tan δ 0.2) and endurance testing oriented to AV applications help maintain consistent audio performance over time.
• Measurable ripple performance — Ripple current ratings at both low and high frequencies (120 Hz and 10 kHz) support designers targeting power integrity across the audio frequency spectrum.
• Durability in elevated temperatures — 2000-hour rating at 85°C with defined limits on capacitance change and leakage supports predictable lifecycle behavior in installed systems.
• Through-hole, serviceable package — Radial-lead can with 7.5 mm spacing simplifies assembly, replacement, and prototyping in bench and production designs.
• Regulatory compliance — RoHS-compliant construction aligns with modern environmental requirements.
