UKZ2A330MPM

The UKZ2A330MPM is a premium-grade aluminum electrolytic capacitor from Nichicon’s UKZ (nichicon MUSE) acoustic series, designed specifically for audio applications. It is a radial-lead, polarized can-type capacitor targeted at first-class audio equipment where audible performance and component reliability are required.

Key elements include a 33 µF capacitance at 100 V rating, RoHS compliance, and engineered endurance for long-term operation at elevated temperatures (1000 hours at 85 °C).

Key Features

• Audio-focused construction – Part of the nichicon MUSE acoustic series, optimized for use in high-quality audio equipment and circuits.
• Electrical specifications – Rated capacitance 33 µF with ±20% tolerance and rated voltage of 100 V, suitable for a range of audio circuit functions.
• Low loss – Maximum tan δ of 0.07 (measured at 120 Hz, 20 °C for 100 V rating) for reduced dissipation in audio signal paths.
• Leakage performance – Leakage current specified as 0.01CV or less after one minute’s application of rated voltage at 20 °C, supporting stable bias behavior.
• Package and mounting – Radial lead, can-style package with 5 mm lead spacing and compact physical size (L: 2 cm × D: 1 cm) for through-hole PCB assemblies.
• Thermal and lifetime – Operating temperature range –40 °C to +85 °C and endurance rated for 1000 hours at 85 °C.
• Compliance and identification – RoHS compliant; sleeve marking printed in gold on a black sleeve for clear part identification.

Typical Applications

• High-end audio equipment – Use in first-class audio systems where component selection affects audible quality and circuit stability.
• Audio signal coupling and decoupling – Suitable for coupling/decoupling stages in audio signal paths where low loss and stable capacitance are important.
• Audio power supply filtering – Applied for smoothing and decoupling in audio power rails requiring a 100 V rated polarized capacitor.
• OEM audio designs – Appropriate for integration into consumer and professional audio products that specify premium acoustic-grade components.

Unique Advantages

• Purpose-built for audio: Part of Nichicon’s MUSE acoustic series, explicitly positioned for high-quality audio equipment.
• Verifiable electrical performance: 33 µF at 100 V with a defined tan δ (0.07 max at 100 V) and leakage current spec of 0.01CV, enabling predictable behavior in audio circuits.
• Compact radial can: Small footprint (L: 2 cm × D: 1 cm) and 5 mm lead spacing make it easy to fit in tight through-hole PCB layouts.
• Durability at elevated temperature: Rated for 1000 hours at 85 °C, supporting sustained operation in thermally demanding installations.
• Regulatory compliance: RoHS compliant, simplifying environmental compliance for product builds.
