UKW1H332MHD

The UKW1H332MHD is a radial-lead aluminum electrolytic capacitor in the UKW series designed for audio and AV equipment. It provides 3300 µF capacitance at a 50 V rating with a ±20% tolerance and a radial can package (φ18 × 35.5 mm) intended for through-hole mounting.

Engineered for power smoothing and decoupling in audio applications, this part offers high ripple-current capability, controlled dissipation (tanδ), RoHS compliance, and a 2000-hour endurance at 85°C for reliable operation in long-life designs.

Key Features

• High Capacitance and Voltage: 3.3 mF (3300 µF) rated at 50 V for bulk energy storage and smoothing in power rails.
• Designed for Audio/AV Equipment: Part of Nichicon's UKW series specifically noted for use in audio equipment—electrolyte and construction tuned for harmonious sound performance.
• Low Loss (tanδ): 0.16 tanδ (DF) measured at 20°C and 120 Hz, supporting low dissipation in audio-frequency circuits.
• High Ripple Current Capability: 2360 mA at 120 Hz (low frequency) and 2714 mA at 10 kHz (high frequency) to handle AC stress and improve filtering performance.
• Reliability & Endurance: Rated for 2000 hours at 85°C with defined capacitance, tanδ, and leakage current limits after endurance testing.
• Leakage Current Specified: 4950 µA listed for the part to enable predictable bias and discharge calculations in designs.
• Package & Mounting: Radial lead, can-style package with 7.5 mm lead spacing and bulk/bag packing suitable for manual insertion and automated radial handling.
• Operating Temperature Range: –40°C to +85°C to support a broad range of environmental conditions in consumer and professional AV equipment.
• Regulatory Compliance: RoHS compliant as provided in the product data.

Typical Applications

• Audio Power Supplies: Bulk smoothing and decoupling for amplifier supply rails where high capacitance and controlled dissipation support stable audio performance.
• AV and Home Entertainment Equipment: Energy storage and ripple suppression in receivers, preamplifiers, and powered speakers to help maintain low-noise power delivery.
• Power Filtering for Analog Circuits: Local decoupling in analog front-ends and bias supplies that benefit from high capacitance and specified leakage current.

Unique Advantages

• High energy density at 50 V: 3300 µF in a φ18 × 35.5 mm can provides substantial bulk capacitance while conserving PCB area and enclosure space.
• Audio-oriented construction: Series design aimed at audio/AV use leverages an electrolyte formulation tuned for sound-quality-focused applications.
• Measured low dissipation: 0.16 tanδ at 120 Hz helps minimize heat and losses in audio-frequency filtering applications.
• Robust ripple handling: Combined low- and high-frequency ripple current ratings (2360 mA @120 Hz, 2714 mA @10 kHz) support effective filtering across a wide frequency range.
• Long endurance rating: 2000 hours at 85°C provides predictable aging behavior for designs requiring extended operational life.
• Predictable leakage: Specified leakage current (4950 µA) enables designers to account for bias currents and discharge behavior accurately.
