UFW0J332MPD

The UFW0J332MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series, designed for audio equipment. It provides high capacitance (3,300 µF) at a low rated voltage (6.3 V) in a compact φ10 × 20 mm can package, making it suitable for space-constrained audio designs that require bulk energy storage and stable performance over temperature.

Key value comes from its combination of high ripple-current capability, long endurance at elevated temperature, and a temperature range appropriate for consumer and professional audio environments.

Key Features

• Capacitance & Tolerance — 3.3 mF (3,300 µF) nominal with ±20% tolerance at 120 Hz, 20°C, providing substantial bulk filtering and energy reserve for audio circuits.
• Rated Voltage — 6.3 V DC rating suitable for low-voltage audio power rails and decoupling applications.
• High Ripple Current Capability — Rated ripple current of 1.17 A at 120 Hz (low frequency) and 1.345 A at 10 kHz (high frequency), supporting demanding ripple conditions in power-supply and amplifier stages.
• Low Leakage — Specified leakage current of 623.7 µA, supporting stable bias conditions in sensitive circuits.
• Endurance — 2,000 hours life at 85°C with retained capacitance within ±20% and leakage current within initial specified limits, suitable for sustained operation in warm environments.
• Compact Radial Can Package — φ10 × 20 mm can with radial lead mounting, 5 mm lead spacing (±0.5 mm tolerance), and a 0.6 mm lead diameter typical for φ10 can construction; bulk (no terminal forming) / bag packing available.
• Operating Temperature Range — −40°C to +85°C for broad environmental compatibility within typical audio equipment.
• Series Focus — Part of Nichicon’s UFW family, a standard series characterized in the datasheet as “For Audio Equipment,” with gold sleeve and black printed marking for clear identification.
• Frequency Ripple Coefficient (Series Data) — For capacitances in the 1,000–10,000 µF range (applicable to this part), the frequency coefficient of rated ripple current is 1.00 at 120 Hz and 1.15 at 10 kHz or more, indicating improved high-frequency ripple handling compared with lower frequency operation.

Typical Applications

• Audio Equipment — Designed for use in audio equipment where large bulk capacitance and reliable ripple handling are required for power supply smoothing and energy buffering.
• Audio Power Stages — Suitable for power rail decoupling and energy reserve in amplifier modules within audio systems.
• Audio Signal Systems — Applicable where polarized electrolytic capacitance is needed as part of circuit filtering and stabilization in audio electronics.

Unique Advantages

• High Bulk Capacitance in a Small Footprint: 3,300 µF in a φ10 × 20 mm can delivers substantial energy storage while minimizing PCB space.
• Robust Ripple Handling: Rated ripple currents of 1.17 A (120 Hz) and 1.345 A (10 kHz) support both low- and high-frequency ripple environments common in audio power supplies.
• Long Endurance at Elevated Temperature: 2,000 hours at 85°C ensures sustained performance and predictable ageing behavior in warm operating conditions.
• Wide Operating Temperature Range: −40°C to +85°C compatibility helps maintain performance across typical environmental conditions encountered by audio products.
• Manufacturer Series Alignment: Part of Nichicon UFW “For Audio Equipment” series, providing consistent characteristics and identification (gold sleeve with black print) for audio-oriented designs.
