UFW1H103MRD

The UFW1H103MRD is a Nichicon UFW-series aluminum electrolytic capacitor in a radial-lead can designed for audio equipment and related power-filtering applications. It delivers high bulk capacitance—10,000 µF—at a 50 V rating, combining energy storage and transient handling in a compact φ25 × 50 mm package with 12.5 mm lead spacing.

Engineered for sustained operation, the part specifies 2,000 hours of endurance at 85°C and supports substantial ripple currents at both low and high frequencies, making it suitable for power reservoir and decoupling roles in audio power supplies and amplifier circuits.

Key Features

• High Capacitance & Voltage: 10,000 µF capacitance rated at 50 V provides substantial energy storage for supply smoothing and reservoir use in audio power stages.
• Radial Can Package: φ25 × 50 mm radial, can-style package with 12.5 mm lead spacing simplifies board-level mounting and through-hole assembly.
• Ripple Current Handling: 4,000 mA at 120 Hz (low frequency) and 4,600 mA at 10 kHz (high frequency) support heavy AC ripple and dynamic audio load demands.
• Loss and Leakage Characteristics: Specified tan δ of 0.30 at 20°C/120 Hz and listed leakage current of 15,000 µA enable designers to evaluate dissipation and self-discharge for thermal and bias budgeting.
• Endurance & Temperature Range: Rated for 2,000 hours at 85°C with an operating temperature range of −40°C to +85°C for designs exposed to elevated ambient conditions.
• Polarized Design & Tolerance: Polarized construction with ±20% capacitance tolerance at 20°C/120 Hz for predictable performance in DC-biased circuits.
• Packaging Options: Available in bulk (no terminal forming) and bag packing for flexible procurement and assembly workflows.

Typical Applications

• Audio Power Supplies: Bulk energy storage and smoothing for amplifier power rails, helping maintain stable supply during high dynamic audio demands.
• Amplifier Reservoir Capacitor: Local energy reservoir for power amplifiers to support transient currents and reduce supply sag during peaks.
• Power Filtering for Audio Equipment: Filtering of rectified supplies and decoupling in audio electronics where large capacitance and ripple capability are required.

Unique Advantages

• Substantial Energy Density: 10,000 µF at 50 V offers large charge storage in a compact φ25 × 50 mm can, reducing the need for multiple smaller capacitors.
• High Ripple Capability: 4.0 A (120 Hz) and 4.6 A (10 kHz) ripple ratings enable reliable operation under both mains-derived and high-frequency switching or audio ripple conditions.
• Designed for Audio Use: Part of the UFW series specified "for audio equipment," aligning the electrical profile with audio-focused power supply requirements.
• Extended Endurance at Elevated Temperature: 2,000-hour rating at 85°C provides predictable life characteristics for designs exposed to sustained thermal stress.
• Through-Hole, Serviceable Form Factor: Radial-lead can package with standard lead spacing supports robust mechanical mounting and repairability in field-serviceable equipment.
