UFW1J470MED

The UFW1J470MED is a radial-leaded aluminum electrolytic capacitor from Nichicon’s UFW series, purpose-built for audio equipment applications. It delivers 47 µF capacitance at a 63 V rating in a compact φ6.3 × 11 mm can with 2.5 mm lead spacing.

Designed for engineers who need reliable smoothing and decoupling in audio circuits, this part combines a compact radial-can package with specified ripple current capability and a 2000-hour endurance at 85 °C for predictable long-term operation.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, suitable for mid‑voltage audio circuit nodes.
• Radial Can Package — φ6.3 × 11 mm radial, can-style package with 2.5 mm lead spacing for through-hole assemblies and hand or wave soldering workflows.
• Ripple Current Performance — Rated ripple currents of 165 mA at 120 Hz and 330 mA at 10 kHz, backed by frequency-coefficient data for 33–47 µF values.
• Low Leakage — Specified leakage current of 88.83 µA, providing predictable standby behavior in bias and coupling circuits.
• Endurance — Endurance specification of 2000 hours at 85 °C with post-test limits defined for capacitance, tan δ, and leakage current.
• Operating Temperature Range — Rated for operation from −40 °C to +85 °C to support typical consumer and professional audio environments.

Typical Applications

• Audio Equipment — Intended for use in audio equipment; suitable for power supply smoothing and decoupling in amplifiers and preamps.
• Signal Coupling/Decoupling — Compact radial form factor makes it useful where board-level through-hole coupling or decoupling capacitors are required.
• Consumer and Professional Audio Electronics — Appropriate for designs requiring a 63 V rated electrolytic with defined ripple and endurance characteristics.

Unique Advantages

• Compact Radial Can — Small φ6.3 × 11 mm footprint and 2.5 mm lead spacing enable space-efficient through-hole layouts.
• Defined Ripple Capability — Explicit ripple current ratings at 120 Hz (165 mA) and 10 kHz (330 mA) allow engineers to size capacitors against measured ripple loads.
• Predictable Leakage — Specified leakage current value (88.83 µA) supports predictable bias behavior in low-current audio circuits.
• Long Endurance at Elevated Temperature — 2000 hours at 85 °C endurance gives a clear reliability baseline for thermal stress planning.
• Wide Operating Temperature Range — −40 °C to +85 °C rating covers typical environmental conditions for audio electronics.
