UKW1C331MPD

The UKW1C331MPD is a Nichicon UKW series aluminum electrolytic capacitor specified for audio and AV equipment. It is a radial-lead, polarized can designed to provide bulk energy storage and filtering in audio circuitry with a focus on sound-quality-oriented performance.

Key attributes include 330 µF capacitance at 16 V, a low-loss characteristic (tanδ = 0.20 at 20°C/120 Hz), rated ripple performance across low and high frequencies, and a 2000-hour endurance at 85°C—delivering stable performance across the component's specified temperature range.

Key Features

• Capacitance & Rated Voltage: 330 µF nominal capacitance rated at 16 V for bulk decoupling and power smoothing in low-voltage audio circuits.
• Low-Loss Dielectric: Tangent of loss angle (tanδ) of 0.20 measured at 20°C and 120 Hz, supporting lower dissipation in audio signal power rails.
• Ripple Current Capability: Low-frequency ripple current 360 mA at 120 Hz and high-frequency ripple current 540 mA at 10 kHz, enabling robust filtering across common audio bandwidths.
• Leakage Current: Typical leakage current of 158.4 µA (per product data), helping minimize standby losses and DC offset contribution in sensitive circuits.
• Endurance: Rated for 2000 hours at 85°C with defined limits for capacitance change, tanδ, and leakage after the endurance test.
• Operating Temperature: −40°C to +85°C, suitable for typical indoor AV and audio electronics environments.
• Package & Mechanical: Radial lead can, size φ8 × 11.5 mm (D × L), lead spacing 3.5 mm (±0.5 mm), supplied in bulk or bag packing without terminal forming.
• Compliance: RoHS compliant, consistent with environmental directive requirements noted in the product datasheet.

Typical Applications

• Audio Equipment: Bulk smoothing and power supply decoupling in amplifiers, preamplifiers, and other AV components where low-loss, sound-focused capacitors are required.
• AV Systems: Power filtering in receivers, home theater components, and consumer AV modules benefiting from stable ripple performance across low and high frequencies.
• Signal Power Rails: Local energy storage and transient suppression for low-voltage analog and mixed-signal audio circuits to maintain signal integrity.

Unique Advantages

• Designed for audio quality: Part of Nichicon’s UKW series developed with an electrolyte targeted at achieving a harmonious sound balance for AV and audio applications.
• Balanced ripple performance: Specified ripple currents at both 120 Hz and 10 kHz support filtering across the frequency range relevant to audio power supplies.
• Compact radial footprint: φ8 × 11.5 mm can and 3.5 mm lead spacing provide a small, serviceable package for densely populated PCBs.
• Long endurance at elevated temperature: 2000 hours at 85°C assures predictable aging and reliability characteristics for product life-cycle planning.
• Low leakage: Measured leakage current of 158.4 µA reduces unwanted DC leakage contribution in sensitive circuits.
• Regulatory compliance: RoHS compliant for use in designs that require restricted-substance adherence.
