UKZ1E330MPM

The UKZ1E330MPM is a premium-grade aluminum electrolytic capacitor from Nichicon’s UKZ (nichicon MUSE) acoustic series, designed specifically for audio equipment. It is a polarized, radial-lead can capacitor optimized for signal-path and power-decoupling use in first-class audio applications.

This part provides 33 µF at 25 V with a compact radial package and is RoHS compliant, offering a combination of low-loss performance and proven endurance for professional and high-fidelity audio designs.

Key Features

• Electrical Performance — 33 µF rated capacitance at 25 V with ±20% tolerance; low-loss characteristic with tan δ (max.) of 0.12 at 25 V (measured at 120 Hz, 20°C).
• Leakage Specification — Leakage current specified as 0.01CV or less after one minute at rated voltage and 20°C, supporting stable bias behavior in audio circuits.
• Acoustic-Grade Design — Part of Nichicon’s MUSE acoustic series, intended for first-class audio equipment and optimized for audible performance in signal paths and coupling applications.
• Reliability & Endurance — Rated for operation from –40°C to +85°C with endurance characterized at 1000 hours at 85°C (capacitance change within ±20%, tan δ ≤150% of initial spec, leakage ≤ initial spec).
• Mechanical & Mounting — Radial lead, can-style package with 3.5 mm lead spacing; compact dimensions L: 1.15 cm × D: 0.8 cm and gold-on-black sleeve marking for polarity identification.
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863), suitable for use in regulated markets.
• Anti-Solvent Feature — Delivered with features noted in the series data for resistance to solvent effects encountered during assembly processes.

Typical Applications

• High-Fidelity Preamplifiers: Used for coupling and decoupling in signal paths where low loss and stable leakage are important for preserving audio fidelity.
• Headphone and Line-Level Amplifiers: Provides local power decoupling and smoothing in compact audio amplifier stages.
• Digital-to-Analog Converters (DACs): Employed on analog output stages and reference circuits where stable capacitance and low tan δ improve analog performance.
• Professional Audio Gear: Suitable for mixers, signal conditioners, and other first-class audio equipment requiring reliable, long-life electrolytic capacitors.

Unique Advantages

• Audio-focused formulation: Part of the nichicon MUSE acoustic series, explicitly intended for first-class audio equipment and audible performance considerations.
• Low-loss behavior: Specified tan δ (max. 0.12 at 25 V) supports lower dissipation in audio signal paths, aiding clarity and dynamic response.
• Predictable leakage control: Leakage current guaranteed at 0.01CV or less after one minute at rated voltage, enabling consistent bias conditions in sensitive circuits.
• Compact radial package: Small 0.8 cm diameter and 1.15 cm length with 3.5 mm lead spacing simplifies placement in space-constrained audio PCBs.
• Endurance-tested: 1000-hour endurance at 85°C with defined limits on capacitance change, tan δ, and leakage ensures long-term stability under rated conditions.
• RoHS compliance: Meets RoHS directives for use in regulated product lines and markets.
