UFW1V470MDD

The UFW1V470MDD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series, specified for audio equipment. It delivers 47 µF capacitance at a 35 V rating in a compact φ5 × 11 mm can with 2 mm lead spacing, making it suitable for space-constrained board layouts.

Designed for reliable operation across a wide temperature range (−40 °C to 85 °C), this polarized capacitor combines low loss (tanδ 0.14 at 20 °C, 120 Hz) with defined ripple current performance and a 2000-hour endurance at 85 °C.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Low Dissipation Factor — tanδ of 0.14 (max) measured at 20 °C and 120 Hz, supporting efficient operation in audio circuits.
• Ripple Current Performance — Specified low-frequency ripple current of 120 mA at 120 Hz and high-frequency ripple current of 240 mA at 10 kHz (33–47 µF frequency coefficient applies).
• Leakage Current — Low leakage current specified (49.35 µA as provided for this part).
• Endurance — Rated for 2000 hours of operation at 85 °C with capacitance change within ±20% and leakage current within initial specified limits after the endurance test.
• Package & Mounting — Radial lead can (φ5 × 11 mm), 2 mm lead spacing (±0.5 mm), supplied in bulk/bag packing for manual assembly or through-hole processes.
• Operating Temperature Range — −40 °C to 85 °C for reliable performance across typical audio-environment conditions.

Typical Applications

• Audio Equipment — Specified for audio equipment applications where a compact 47 µF, 35 V polarized capacitor is required.
• Compact Consumer Electronics — Suited to small form-factor boards that require through-hole radial electrolytic capacitors with defined ripple and endurance characteristics.
• General Purpose Power Filtering — Useful in circuits needing defined ripple handling and low dissipation at audio-relevant frequencies.

Unique Advantages

• Compact radial can — φ5 × 11 mm package provides a small footprint for tight board layouts while retaining a robust can-style construction.
• Audio-focused specification — UFW series designation and measured tanδ target the needs of audio equipment applications.
• Clear ripple-current ratings — Both low-frequency (120 Hz) and high-frequency (10 kHz) ripple current specifications allow designers to match the part to switching and audio-frequency environments.
• Defined endurance — 2000 hours at 85 °C gives a quantifiable lifetime metric for thermal-stress planning and reliability forecasting.
• Wide operating temperature — −40 °C to 85 °C supports deployment across varied ambient conditions common in consumer and professional audio gear.
• Through-hole mounting — Radial lead format and standard lead spacing simplify prototyping and replacement on legacy or mixed-technology assemblies.

Why Choose UFW1V470MDD?

UFW1V470MDD provides a balanced combination of compact size, audio-oriented electrical characteristics, and documented endurance. Its low dissipation factor at 120 Hz, defined ripple current ratings at both low and high frequencies, and low leakage current make it a practical choice where predictable audio performance and long-term stability are required.

This part is well suited to engineers specifying a 47 µF, 35 V polarized aluminum electrolytic in a radial can for audio and compact electronic designs that demand measured performance and clear lifetime data.
