UKZ2A331MHM

The UKZ2A331MHM is a premium-grade aluminum electrolytic capacitor from Nichicon’s MUSE acoustic series, designed specifically for audio equipment. This radial-lead, polarized can delivers 330 µF at a 100 V rating with a compact 3.55 × 1.8 cm package and 7.5 mm lead spacing.

Targeted at first-class audio applications, the part combines low-loss characteristics, RoHS compliance, and an endurance rating specified for extended operation at elevated temperature, making it suitable for designers of high-quality audio systems.

Key Features

• Premium MUSE acoustic series Nichicon "MUSE" premium grade designed for audio equipment and acoustic performance.
• Capacitance & voltage 330 µF rated capacitance with a 100 V working voltage to support higher-voltage audio circuits.
• Low loss (tan δ) Specified low tangent of loss angle with a maximum tan δ of 0.07 at 100 V (measured at 120 Hz, 20°C), supporting efficient audio performance.
• Leakage current specification Leakage current defined as 0.01CV or less after 1 minute’s application of rated voltage at 20°C, providing predictable bias behavior.
• Thermal and endurance rating Operating range –40°C to +85°C with an endurance specification of 1000 hours at 85°C; capacitance change is within ±20% after the endurance test when restored to 20°C.
• Radial can package Radial lead, can-style package (L: 3.55 × D: 1.8 cm) with 7.5 mm lead spacing for through-hole mounting and simple board integration.
• Anti-solvent feature & marking Anti-solvent feature for production robustness; printed with gold lettering on a black sleeve for clear polarity and identification.
• RoHS compliant Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑end audio equipment Designed for first-class audio systems where acoustic quality and stable performance are required.
• Audio power supply sections Suitable for use in audio power supply filtering and decoupling where 100 V rating and 330 µF capacitance are needed.
• Audio components and modules Applicable to discrete audio modules and board-level assemblies that specify radial-lead electrolytic capacitors from a premium acoustic series.

Unique Advantages

• Audio-focused grade: Part of Nichicon’s MUSE acoustic series, explicitly intended for audio equipment and acoustic performance considerations.
• Measurable low-loss behavior: Specified tan δ of 0.07 at 100 V (120 Hz, 20°C) helps minimize loss in critical audio paths.
• Defined leakage behavior: Leakage current limited to 0.01CV or less after initial voltage application, enabling predictable design margins.
• Durability at elevated temperature: Endurance defined as 1000 hours at 85°C with capacitance change within ±20%, supporting long-term stability in warm operating environments.
• Clear polarity and assembly-friendly package: Gold-on-black sleeve marking and radial lead can format simplify identification and through-hole assembly.
• Regulatory compliance: RoHS compliance aligns with environmental requirements for modern electronics manufacturing.
