UFW1H331MPD

The UFW1H331MPD is a radial-leaded aluminum electrolytic capacitor from Nichicon’s UFW series, specified for audio applications. It provides 330 µF capacitance at a 50 V rating in a compact φ10 × 16 mm can with polarized radial leads.

Designed for use in audio equipment and related power/filtering circuits, this capacitor delivers specified ripple current capability, controlled dissipation factor, and a 2000-hour endurance at 85°C for sustained performance in typical audio-system environments.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, suitable for mid-voltage audio power and filtering tasks.
• Radial Through-Hole Package: φ10 × 16 mm aluminum can with 5 mm lead spacing and radial lead mounting for through-hole assembly and retrofit-friendly designs.
• Dissipation Factor (tan δ): tanδ = 0.12 measured at 20°C, 120 Hz, 50 V, providing predictable loss characteristics for audio-frequency applications.
• Ripple Current Capability: Low-frequency ripple current 570 mA at 120 Hz and high-frequency ripple current 855 mA at 10 kHz, supporting power smoothing and decoupling across audio bandwidths.
• Leakage Current: Specified leakage current of 495 µA, measured under the stated conditions for reliable bias performance.
• Endurance & Temperature Range: Rated lifetime of 2000 hours at 85°C and an operating temperature range of −40°C to +85°C for consistent long-term operation.
• Polarized Component: Polarized electrolytic construction for correct orientation in DC circuits.
• Packaging Options: Available in bulk (no terminal forming) or bag packing to suit assembly and inventory workflows.

Typical Applications

• Audio Power Supply Filtering: Bulk decoupling and smoothing in audio amplifiers and preamplifiers to maintain stable rail voltage and reduce hum.
• Signal Chain Bypass/Decoupling: Local supply decoupling for analog stages and driver circuits where 330 µF at 50 V is required.
• Consumer and Pro Audio Equipment: Through-hole implementation in PCB designs and repair/retrofit scenarios for audio electronics.

Unique Advantages

• Balanced Capacitance-to-Size Ratio: 330 µF in a φ10 × 16 mm can enables substantial energy storage without a large PCB footprint.
• Measured Loss Characteristics: tanδ = 0.12 at 120 Hz, 20°C gives predictable AC loss behavior important for audio performance tuning.
• High-Frequency Ripple Support: Specified 855 mA ripple at 10 kHz supports decoupling across audio-relevant frequency ranges.
• Extended Endurance: 2000 hours at 85°C supports reliable operation under elevated-temperature conditions common in audio enclosures.
• Through-Hole Robustness: Radial lead configuration simplifies assembly, mechanical retention, and replacement in serviceable equipment.
• Packaged for Production: Available in bulk or bag packing to match production or repair needs.
