UFW1E470MDD

The UFW1E470MDD is a 47 µF, 25 V polarized aluminum electrolytic capacitor in a radial can package from Nichicon’s UFW series, engineered for audio equipment and related electronics. It combines compact dimensions (φ5 × 11 mm) and a -40 °C to 85 °C operating range with endurance rated to 2000 hours at 85 °C for stable performance in temperature-challenging environments.

Designed for through-hole radial-lead mounting, this part is suited to power-filtering and decoupling roles where space-constrained, audio-focused designs require dependable capacitance, controlled dissipation (tan δ), and defined ripple-current capability.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a rated voltage of 25 V and ±20% tolerance at 120 Hz, 20 °C, providing predictable energy storage for signal and power rails.
• Audio-grade Series — Part of Nichicon’s UFW series specified for audio equipment; loss tangent (tan δ) is 0.16 max at 25 V (120 Hz, 20 °C), supporting low-loss operation in audio circuits.
• Ripple Current Performance — Low-frequency ripple current of 115 mA at 120 Hz and high-frequency ripple current of 230 mA at 10 kHz, enabling effective ripple handling across common audio and power-supply frequencies.
• Leakage Current — Specified leakage current value of 35.25 µA, suitable for applications requiring low standby leakage.
• Robust Temperature & Lifetime — Operating range from -40 °C to 85 °C with endurance tested to 2000 hours at 85 °C, supporting sustained operation in elevated ambient conditions.
• Compact Radial Package — φ5 × 11 mm can with 2.0 mm lead spacing (±0.5 mm tolerance) and radial lead mounting for straightforward through-hole assembly and mechanical stability.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible inventory and assembly workflows.

Typical Applications

• Audio Equipment — Power supply smoothing and decoupling in amplifiers, preamps, and signal-processing modules where low loss and reliable ripple handling are important.
• Power Filtering — Local bulk and decoupling capacitor in low-voltage power rails (25 V) for consumer and pro-audio electronics.
• Embedded & Consumer Electronics — Space-conscious through-hole designs requiring a compact 47 µF capacitor with solid temperature and endurance characteristics.

Unique Advantages

• Audio-focused design: UFW series specification and a controlled tan δ (0.16 at 25 V, 120 Hz) align the part to audio applications needing consistent loss characteristics.
• Measured ripple capability: Explicit low- and high-frequency ripple current ratings (115 mA at 120 Hz; 230 mA at 10 kHz) let designers size components deterministically for both supply and high-frequency noise conditions.
• Compact footprint: φ5 × 11 mm radial can and 2.0 mm lead spacing provide a small through-hole solution for constrained PCB areas.
• Wide temperature range and defined endurance: -40 °C to 85 °C operating range and 2000 hours at 85 °C endurance offer predictable life performance in elevated-temperature assemblies.
• Low leakage: Specified leakage current (35.25 µA) supports designs sensitive to standby losses and bias stability.
• Flexible packing: Bulk or bag packing options simplify handling for prototype builds or low-volume production runs.
