UES1H331MHM

The UES1H331MHM is a bi‑polarized aluminum electrolytic capacitor from Nichicon’s UES "MUSE" acoustic series, designed specifically for audio signal circuits and audio equipment. As a radial‑lead, can‑package capacitor, it offers audio‑focused electrical characteristics and RoHS compliance for use in through‑hole audio designs.

Key Features

• Audio‑focused construction Bi‑polarized "nichicon MUSE" acoustic series, explicitly suited for audio signal circuits and audio equipment.
• Capacitance & voltage 330 µF nominal capacitance at a rated voltage of 50 V with a tolerance of ±20% (–20%~20%).
• Electrical performance Specified tangent of loss angle (tan δ) maximum of 0.12 at 50 V (measured at 120 Hz, 20 °C) and leakage current specified as not more than 0.03CV (µA) after one minute at 20 °C.
• Reliability & endurance Rated for 1,000 hours at 85 °C (endurance test with polarity inversion every 250 hours) with capacitance change within ±20% and leakage current meeting initial specified value after test.
• Operating environment Operating temperature range of −40 °C to +85 °C.
• Package & mounting Radial lead, can package with lead spacing of 7.5 mm and physical size L: 3.05 × D: 1.6 cm, suitable for standard through‑hole PCB layouts.
• Regulatory compliance Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Identification Marked with black letters on a clear green sleeve for quick visual verification.

Typical Applications

• Audio Equipment — Designed for use in audio devices where bi‑polarized electrolytic capacitors are required for signal paths.
• Audio Signal Circuits — Suited to coupling/decoupling and signal conditioning roles within analog audio circuitry.
• Professional and Consumer Audio Systems — Applicable where radial lead, through‑hole capacitors are preferred for board layout or serviceability.

Unique Advantages

• Purpose‑built for audio: The MUSE acoustic series formulation and bi‑polarized design target audio signal integrity and application flexibility in audio circuits.
• Clear electrical limits: Defined tan δ (0.12 max at 50 V, 120 Hz, 20 °C) and leakage current (≤0.03CV µA after 1 minute) provide predictable behavior for filter and coupling applications.
• Through‑hole, serviceable package: Radial lead can and a 7.5 mm lead spacing simplify PCB layout and allow easier replacement or rework in prototypes and field service.
• Engineered for expected life at elevated temperature: 1,000‑hour endurance rating at 85 °C supports designs that require verified thermal longevity.
• RoHS compliant: Meets RoHS (2011/65/EU, (EU)2015/863) requirements for material restriction in modern electronic products.
