UES1V331MHM

The UES1V331MHM is a bi-polarized aluminum electrolytic capacitor from Nichicon’s UES "MUSE" acoustic series, designed specifically for audio signal circuits and audio equipment. It provides 330 µF capacitance at a 35 V rating in a compact radial-can package intended for audio-path coupling, decoupling and signal-processing stages.

Built for acoustic applications, this component combines a bipolar design with defined electrical and environmental characteristics to support stable audio performance across a wide temperature range while meeting RoHS requirements.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance at a rated voltage of 35 V suitable for audio signal applications requiring mid-range bulk and coupling capacitance.
• Bi-polarized Design — Bi-polar construction intended for audio circuits where polarity reversal or AC coupling occurs.
• Electrical Characteristics — Capacitance tolerance ±20% at 120 Hz, 20 °C; maximum tan δ of 0.14 at 35 V (measured at 120 Hz, 20 °C); leakage current specified as not more than 0.03CV (µA) after 1 minute at 20 °C.
• Reliability & Endurance — Rated for 1000 hours at 85 °C with the endurance requirement that capacitance change remains within ±20% after the test with polarity inversion every 250 hours; leakage current remains less than or equal to the initial specified value.
• Temperature Performance — Operating temperature range from −40 °C to +85 °C with impedance stability defined (Z(−25 °C)/Z(+20 °C) and Z(−40 °C)/Z(+20 °C) ratios provided in the series datasheet).
• Package & Mounting — Radial lead, radial-can package with 7.5 mm lead spacing and compact physical dimensions (L: 2.5 cm × D: 1.6 cm), marked with black lettering on a clear green sleeve.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Signal Circuits — Suited for coupling and signal-path applications in audio circuitry where bi-polarized operation is required.
• Audio Equipment — Intended for use in audio equipment and acoustic systems as part of preamplifier, filter, or buffering stages.
• Electro-acoustic Modules — Appropriate for modules handling audio signals that benefit from defined low-frequency capacitance and temperature endurance.

Unique Advantages

• Audio-focused Bi-polar Design: Specifically built for audio signal circuits, enabling AC coupling and polarity-reversal tolerance common in audio paths.
• Measured Loss and Leakage Specs: Defined tan δ (0.14 at 35 V) and a leakage current limit of 0.03CV (µA) support predictable behavior in signal-sensitive designs.
• Endurance Under Stress: 1000-hour rated life at 85 °C with polarity inversion testing provides a measurable reliability baseline for thermal and electrical endurance planning.
• Compact Radial Can Package: Small footprint (2.5 cm × 1.6 cm) with radial lead spacing (7.5 mm) simplifies layout for through-hole audio assemblies.
• RoHS Compliance: Conforms to applicable RoHS directives, aiding regulatory alignment for end products.
