UKZ1E331MHM

The UKZ1E331MHM is a premium-grade aluminum electrolytic capacitor from Nichicon’s MUSE acoustic series, designed specifically for audio applications. It is a radial-lead, can-style polarized capacitor providing 330 µF capacitance at a 25 V rated voltage.

Engineered for first-class audio equipment, this part combines acoustic-focused design with RoHS compliance and measurable electrical characteristics useful for precision audio circuitry and power filtering in premium systems.

Key Features

• Audio-grade MUSE Series — Premium acoustic series intended for first-class audio equipment, described in the product description as suited where qualitative and quantitative comfortableness is required.
• Electrical Rating — 330 µF capacitance at a 25 V rated voltage with ±20% tolerance (measured at 120 Hz, 20°C).
• Low loss (tan δ) — Specified tan δ of 0.12 for the 25 V rating (measurement frequency 120 Hz, 20°C), providing a defined dissipation factor for audio designs.
• Leakage Current — Leakage current specified as 82.5 µA (measured at 20°C after 1 minute) for this part number.
• Package & Mounting — Radial lead, can-style construction with 5 mm lead spacing and compact dimensions L: 2.5 × D: 1.25 cm (case 12.5 × 25 mm).
• Temperature and Lifetime — Operating temperature range –40°C to +85°C with a rated endurance of 1000 hours at 85°C.
• Environmental Compliance & Marking — RoHS compliant; sleeve marking printed in gold on black.
• Anti-Solvent Feature — Documented in the series notes to address solvent-related concerns during assembly or cleaning processes.

Typical Applications

• High-end audio equipment — Intended for first-class audio systems where premium acoustic performance is a design priority.
• Audio power supply circuits — Useful in power filtering and smoothing roles within premium audio electronics.
• Audio component designs — Suited for use in designers’ audio-focused builds that specify MUSE-series acoustic components and RoHS compliance.

Unique Advantages

• Acoustic-focused design: Part of Nichicon’s MUSE premium acoustic series, selected for applications targeting audio quality and comfort.
• Defined electrical performance: 330 µF at 25 V with specified tan δ (0.12) and leakage current (82.5 µA) for predictable behavior in audio circuits.
• Compact radial can package: 12.5 × 25 mm case with 5 mm lead spacing provides a small-footprint solution for PCB layouts in audio equipment.
• Wide temperature range and proven endurance: –40°C to +85°C operating range and 1000 hours endurance at 85°C support reliability in sustained operating conditions.
• RoHS compliant: Meets RoHS directive (2011/65/EU,(EU)2015/863) requirements for environmentally restricted substances.
• Industry-oriented marking and handling: Gold-on-black sleeve marking and anti-solvent considerations facilitate identification and assembly in production environments.
