UFW1A472MHD

The UFW1A472MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UFW series, designed for audio equipment applications. It provides high bulk capacitance and robust ripple-current capability in a compact φ12.5 × 25 mm can for through-hole mount designs.

With a 10 V rated voltage, ±20% capacitance tolerance, and an operating temperature range of -40°C to 85°C, this part is specified for demanding audio power circuitry where sustained endurance and ripple handling matter.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance at 10 V rated voltage with ±20% tolerance.
• Radial Lead Can Package — φ12.5 × 25 mm can with 5 mm lead spacing for standard through-hole mounting.
• Ripple Current Performance — 1800 mA low-frequency ripple current at 120 Hz and 2070 mA high-frequency ripple current at 10 kHz.
• Loss Tangent (tan δ) — 0.3 (DF) measured at 20°C and 120 Hz.
• Leakage Current — 1410 µA specified leakage current.
• Endurance — 2000 hours life at 85°C with ratings for capacitance change, tan δ and leakage current after endurance testing.
• Operating Temperature Range — Specified for -40°C to 85°C operation.
• Packaging Options — Supplied in bulk (no terminal forming) or in bag packing.

Typical Applications

• Audio Equipment — Suited to power supply filtering and decoupling in audio amplifiers and related audio circuitry where bulk capacitance and ripple handling are required.
• Power Reservoirs — Acts as a local energy reservoir on through-hole boards to support transient loads in audio power stages.
• Power Supply Smoothing — Used where sustained ripple current capability at both low and high frequencies improves supply stability for audio circuits.

Unique Advantages

• High Bulk Capacitance in a Compact Can: 4700 µF in a φ12.5 × 25 mm package provides substantial energy storage for space-conscious through-hole designs.
• Strong Ripple-Current Capability: Rated for 1.8 A at 120 Hz and 2.07 A at 10 kHz, enabling reliable performance under continuous ripple stress.
• Audio-Focused Series: Part of Nichicon's UFW line, specified "for audio equipment" to align with audio power and filtering needs.
• Extended Endurance: 2000 hours at 85°C specification supports long-term operation in temperature-stressed environments.
• Through-Hole Convenience: Radial lead form and standard 5 mm lead spacing simplify PCB layout and manual or automated through-hole assembly.
