UFW1E103MRD

The UFW1E103MRD is a radial-lead aluminum electrolytic capacitor from Nichicon's UFW series, designed for audio equipment and power filtering applications. It delivers 10,000 µF capacitance at a 25 V rating in a compact φ20 × 40 mm can with 10 mm lead spacing.

Key value comes from its high bulk capacitance, defined ripple current capability at both low and high frequencies, and endurance rating of 2000 hours at 85°C, making it suitable for engineers specifying bulk energy storage and smoothing in audio power supplies and related systems. Status: End Of Life.

Key Features

• High Capacitance — 10,000 µF nominal capacitance (±20%), ideal for bulk energy storage and smoothing in power rails.
• 25 V Rated Voltage — Suitable for mid-voltage audio and power supply designs requiring polarized electrolytic bulk capacitance.
• Radial Lead Package — φ20×40 mm aluminum can with 10 mm lead spacing and radial lead mounting for through-hole PCB assembly; available in bulk (no terminal forming) or bag packing.
• Ripple Current Performance — Low-frequency ripple current 3.00 A at 120 Hz and high-frequency ripple current 3.45 A at 10 kHz (frequency coefficient data supports increased allowable ripple at higher frequencies for 1000–10000 µF parts).
• Endurance — Rated life of 2000 hours at 85°C with specified limits on capacitance change, tan δ, and leakage current after test.
• Temperature Range — Operating from −40°C to +85°C to cover a broad range of commercial and industrial ambient conditions.
• Leakage Current — Specified leakage current of 7,500 µA (as provided for this part).
• Audio-Targeted Series — Part of Nichicon’s UFW family specified for audio equipment, with marking printed on a gold sleeve.

Typical Applications

• Audio Power Supplies — Bulk smoothing and decoupling for amplifier rails and audio electronics where large capacitance is needed.
• Audio Amplifiers — Energy reservoir for transient loads in power amplifier designs within the UFW series’ audio-focused use case.
• Consumer and Pro Audio Equipment — Power filtering and stability in mixers, preamps, and other audio-focused electronics that require durable bulk capacitance.

Unique Advantages

• Substantial Energy Storage: 10,000 µF capacity reduces ripple and maintains rail stability under audio load transients.
• Defined Ripple Handling: Published ripple current values at 120 Hz and 10 kHz let designers size capacitors against expected AC stress across frequency.
• Engineered for Audio: Positioned in Nichicon’s UFW audio series, simplifying selection for audio-centric power designs.
• Compact Through-Hole Form Factor: φ20×40 mm radial can with 10 mm lead spacing supports robust mounting and easy replacement in serviceable equipment.
• High-Temperature Endurance: 2000 hours at 85°C provides a clear reliability baseline for thermal design and lifetime planning.
