UKW1C332MHD

The UKW1C332MHD is a Nichicon UKW series aluminum electrolytic capacitor offering 3300 µF capacitance at a 16 V rating in a radial-lead can. It is part of Nichicon's UKW family, developed with an electrolyte formulation targeted at audio and AV equipment.

With a compact φ12.5 × 25 mm package, polarized radial leads and packaging available in bulk or bag, this component addresses high-capacitance smoothing and decoupling requirements where audio performance and compact size matter.

Key Features

• High Capacitance: 3.3 mF (3300 µF) nominal capacitance for energy storage, smoothing and low-frequency decoupling.
• Rated Voltage: 16 V DC rating suitable for common audio and AV supply rails.
• Audio-Optimized Electrolyte: Part of the UKW series developed for a harmonious balance of sound quality, aimed at AV and audio equipment.
• Ripple Current Handling: Low-frequency ripple current 1.7 A (120 Hz) and high-frequency ripple current 1.955 A (10 kHz), supporting demanding supply filtering in audio circuits.
• Loss Tangent / Dissipation Factor: tanδ specified at 0.24 (measured at 20°C, 120 Hz), providing a defined AC loss characteristic for circuit design.
• Leakage Current: Specified leakage current 1584 µA (per product data), allowing predictable standby and bias current budgeting.
• Reliability / Endurance: Rated for 2000 hours at 85°C under rated voltage, with specified limits on capacitance change, tanδ and leakage after the endurance test.
• Environmental Compliance: RoHS compliant.
• Mechanical / Mounting: Radial lead mounting with 5 mm lead spacing (±0.5 mm) and a compact φ12.5 × 25 mm can size for through-hole PCB use.

Typical Applications

• Audio Equipment: Power supply smoothing and bulk energy storage in amplifiers, preamps and other audio circuits where the UKW series' electrolyte formulation is targeted.
• AV Electronics: Voltage decoupling and filtering in consumer AV gear that benefits from the series' sonic-focused design.
• Power Supply Filtering: Bulk and local decoupling on low-voltage DC rails (16 V) to stabilize supplies and reduce ripple in signal paths.

Unique Advantages

• Audio-focused formulation: The UKW series electrolyte is developed to support a harmonious balance of sound quality, making the part suited to AV and audio designs.
• High energy density in a compact can: 3300 µF in a φ12.5 × 25 mm package provides significant capacitance where PCB space is limited.
• Predictable ripple performance: Specified ripple current values at both low and high frequencies help designers size thermal and cooling requirements accurately.
• Defined AC losses and leakage: Specified tanδ and leakage current figures enable reliable AC-loss budgeting and standby current estimates.
• Durability for continuous operation: 2000-hour endurance at 85°C under rated voltage supports sustained performance in elevated-temperature environments.
• Regulatory compliance: RoHS compliance for environmental and materials acceptance in regulated markets.
