UFW1V331MPD

The UFW1V331MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UFW series, designed for audio equipment and other electronic designs that require compact, polarized bulk capacitance. It delivers 330 µF at a 35 V rating with a small φ10 × 12.5 mm can and 5 mm lead spacing, offering a dense capacitor option where board space and reliable audio performance are important.

Key value propositions include moderate ripple-handling capability across low and high frequencies, defined leakage and loss characteristics, and an endurance rating for sustained operation up to 85 °C.

Key Features

• Electrical Rating — 330 µF nominal capacitance at 35 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• Low Loss Characteristics — tanδ 0.14 (maximum at 120 Hz for 35 V), supporting stable performance in audio circuits where low dissipation factor matters.
• Ripple Current Capacity — 470 mA specified at 120 Hz and 705 mA at 10 kHz, enabling handling of both low-frequency and higher-frequency ripple components.
• Leakage Current — 346.5 µA leakage current as specified for this part.
• Temperature and Endurance — Rated for operation from −40 °C to 85 °C with a 2000-hour endurance rating at 85 °C.
• Package and Mounting — Radial lead, can-style package (φ10 × 12.5 mm), 5 mm lead spacing; supplied in bulk/bag packaging suitable for production use.

Typical Applications

• Audio Equipment — Intended for use in audio devices where compact bulk capacitance with defined loss and leakage specifications is required.
• Compact Power Filtering — Suitable for space-constrained power supply filtering in consumer and professional audio products that operate within the capacitor's voltage and temperature limits.
• General Electronic Designs — Useful where a polarized radial electrolytic capacitor with moderate ripple handling and a 35 V rating is needed.

Unique Advantages

• Matched audio-series design — Part of Nichicon’s UFW series, explicitly intended for audio equipment, making specification straightforward for audio-centric designs.
• Balanced ripple capability — Separate ripple current ratings at 120 Hz and 10 kHz allow designers to account for both low- and high-frequency stress when sizing capacitors.
• Compact radial form factor — φ10 × 12.5 mm can with 5 mm lead spacing provides high capacitance in a small footprint for dense PCB layouts.
• Defined endurance and temperature range — 2000 hours at 85 °C and −40 °C to 85 °C operating range provide predictable lifetime behavior for designs with elevated ambient temperatures.
• Clear electrical limits — Specified tanδ, leakage current, and tolerance values make it easier to model performance and ensure component selection aligns with system requirements.
