The UFW1V472MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UFW series, optimized for audio equipment. It delivers high capacitance (4.7 mF) at a 35 V rating in a compact φ18 × 35.5 mm can with through-hole radial leads.

Designed for applications that require substantial energy storage and stable operation across a wide ambient range, this part offers specified ripple-current capability at both low and high frequencies and an endurance rating of 2000 hours at 85°C.

Key Features

• Capacitance & Voltage: 4700 µF (4.7 mF) rated at 35 V with ±20% capacitance tolerance for large energy storage in power rails and reservoir applications.
• Ripple Current: Rated low-frequency ripple current of 2.49 A at 120 Hz and high-frequency ripple current of 2.864 A at 10 kHz to support continuous AC stress in power stages.
• Endurance & Temperature Range: Life/endurance of 2000 hours at 85°C and an operating temperature range of −40°C to +85°C for reliable performance in demanding environments.
• Package & Mounting: Radial can package (φ18 × 35.5 mm) with 7.5 mm lead spacing (±0.5 mm) for straightforward through-hole assembly; available in bulk (no terminal forming) or bag packing.
• Leakage & Polarization: Polarized design with specified leakage current of 4935 µA; suitable for applications that require standard electrolytic capacitor characteristics.
• Audio-Focused Series: Part of Nichicon’s UFW series, specified as "Standard, For Audio Equipment," aligning the device’s characteristics with audio system requirements.

Typical Applications

• Audio Equipment: Reservoir and rail decoupling in consumer and professional audio systems where 4700 µF capacitance supports sustained power delivery.
• Power Supply Filtering: Bulk energy storage and smoothing in low- to mid-voltage DC power supplies within audio and related electronic equipment.
• Amplifier Power Stages: Support for power rails in amplifier modules, leveraging the part's ripple-current ratings and endurance at elevated temperatures.

Unique Advantages

• High Energy Density: 4700 µF at 35 V provides significant charge storage for reservoir and smoothing functions without excessive board area.
