UFW1C331MPD

The UFW1C331MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UFW series, engineered for audio equipment applications. It delivers 330 µF capacitance at a 16 V rating in a compact radial can (φ8 × 11.5 mm) with 3.5 mm lead spacing.

Designed for power and decoupling roles in audio circuits, this capacitor combines a wide operating temperature range (−40°C to 85°C) with specified ripple-handling capability and a 2000-hour endurance rating at 85°C, providing predictable behavior for long-term designs and mass-production use.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance at a 16 V rating with ±20% tolerance for predictable energy storage and decoupling in audio power rails.
• Low-loss Characteristic: tan δ (loss tangent) specified at 0.20 (max) for 16 V parts, supporting stable AC performance in audio applications.
• Ripple Current Capability: Rated ripple current of 360 mA at 120 Hz and 540 mA at 10 kHz, enabling handling of both low- and high-frequency ripple components common in audio power supplies.
• Leakage Current: Specified leakage current of 158.4 µA for controlled stand-by and quiescent current behavior in sensitive circuits.
• Reliability & Lifetime: Endurance rating of 2000 hours at 85°C with restoration to room temperature meeting specified capacitance, tan δ, and leakage characteristics.
• Mechanical & Mounting: Radial-lead can package (φ8 × 11.5 mm) with 3.5 mm lead spacing; bulk/bag packing supports volume assembly and repair-friendly through-hole mounting.
• Operating Temperature Range: −40°C to 85°C for use across a broad range of environmental conditions.

Typical Applications

• Audio equipment power supply decoupling: Stabilizes audio power rails and smooths supply ripple using 330 µF capacitance with ripple ratings of 360 mA at 120 Hz and 540 mA at 10 kHz.
• Audio amplifier systems: Serves as local energy reservoir and bypass capacitor in amplifier modules where compact radial packaging and polarized electrolyte characteristics are required.
• Consumer and professional audio electronics: Suitable for mass-production assemblies where a long endurance (2000 h at 85°C), controlled leakage, and a wide temperature range are required.

Unique Advantages

• Audio-focused series: Part of Nichicon’s UFW series specified for audio equipment, aligning component choice with application needs.
• Balanced ripple performance: Dual ripple specifications at 120 Hz and 10 kHz make behavior at both low and high frequency ripple predictable for audio power systems.
• Compact radial can: φ8 × 11.5 mm package with 3.5 mm lead spacing provides a small footprint for through-hole layouts and straightforward placement in PCB designs.
• Long-term stability: 2000-hour endurance at 85°C and defined restoration criteria help ensure consistent capacitance, loss, and leakage over the specified lifetime.
• Controlled leakage: Specified leakage current supports designs where stand-by and quiescent currents must be bounded.
• Wide operating temperature: −40°C to 85°C operational range supports deployment across varied ambient conditions without loss of specified performance.
