UFW0J331MED

The UFW0J331MED from Nichicon is a radial-lead aluminum electrolytic capacitor designed for audio applications. It delivers 330 µF capacitance at a 6.3 V rating in a compact φ6.3 × 11 mm can with 2.5 mm lead spacing.

Engineered for board-level power decoupling and energy storage in audio circuits, this polarized radial package combines measurable ripple handling and long endurance for reliable performance across a −40°C to 85°C operating range.

Key Features

• Capacitance & Tolerance — 330 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C), suitable for bulk decoupling and smoothing tasks in audio circuits.
• Rated Voltage — 6.3 V DC rating for low-voltage analog and audio power rails.
• Ripple Current Capability — Handles 265 mA at 120 Hz (low frequency) and 397.5 mA at 10 kHz (high frequency), supporting both line-frequency and higher-frequency ripple environments.
• Leakage Current — Specified leakage of 62.37 µA, enabling predictable standby and bias performance in sensitive audio stages.
• Endurance — 2000 hours life at 85°C under rated voltage, meeting defined endurance criteria after recovery to 20°C.
• Thermal Range — Wide operating range from −40°C to 85°C for use across various ambient conditions.
• Form Factor — Radial lead can, φ6.3 × 11 mm (L), 2.5 mm lead spacing; supplied bulk (no terminal forming) or in bag packing to suit assembly workflows.
• Polarized — Designed as a polarized electrolytic for DC power and filtering applications common in audio systems.

Typical Applications

• Audio Power Supply Filtering — Bulk decoupling and smoothing on low-voltage amplifier rails where 330 µF at 6.3 V provides stable supply energy for transient demands.
• Preamp and Signal Chain Decoupling — Use in audio preamplifier and tone-control circuits to stabilize bias and reduce low-frequency ripple.
• Consumer Audio Electronics — Suitable for compact audio devices and portable gear that require a small radial capacitor with defined endurance and temperature range.

Unique Advantages

• Compact radial package: φ6.3 × 11 mm can with 2.5 mm lead spacing provides a small footprint for space-constrained audio PCBs.
• Measurable ripple performance: Specified ripple currents at both 120 Hz and 10 kHz let designers quantify thermal and ripple handling across common audio frequencies.
• Predictable leakage behavior: Defined leakage current supports precise biasing and low-noise designs in sensitive audio circuits.
• Extended endurance at elevated temperature: 2000 hours at 85°C under rated voltage provides a known baseline for lifetime planning in product design.
• Wide operating temperature: −40°C to 85°C supports deployment across varied ambient conditions encountered by consumer and professional audio equipment.
