UES1C331MHM

The UES1C331MHM is a bi‑polarized aluminum electrolytic capacitor from Nichicon’s UES "MUSE" acoustic series, designed specifically for audio equipment and audio signal circuits. Its construction and electrical characteristics target audio designers who require a compact radial‑lead can with bi‑polar capability for signal‑path applications.

Offered with a 330 μF capacitance at 16 V, the UES1C331MHM combines a small footprint (φ12.5 mm × 20 mm) and a radial lead package for ease of placement in through‑hole audio designs while meeting RoHS compliance requirements.

Key Features

• Bi‑Polarized Design Specifically configured for audio signal circuits and the Nichicon MUSE acoustic series.
• Electrical Rating 330 μF nominal capacitance at a 16 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• Low Loss Specified tan δ of 0.16 (measurement at 120 Hz, 20°C) for the 16 V rating.
• Leakage Current Typical leakage current listed as 158.4 μA (at 20°C after 1 minute) for the 16 V / 330 μF variant.
• Compact Radial Can Package φ12.5 mm × 20 mm can with 5 mm lead spacing; radial lead mounting for straightforward through‑hole assembly.
• Operating and Endurance Specs Rated for −40°C to +85°C operation and endurance of 1000 hours at 85°C (with polarity inversion every 250 hours) with defined limits on capacitance change, tan δ, and leakage current.
• RoHS Compliant Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment Suited for audio signal circuits in consumer and professional audio devices that require bi‑polarized coupling or signal handling components.
• Signal Path Components Use in audio modules where a compact radial electrolytic is needed for signal‑stage circuitry within the stated voltage and temperature limits.
• Acoustic and Music Electronics Integration into acoustic‑focused modules consistent with the Nichicon MUSE acoustic series intent.

Unique Advantages

• Audio‑Focused Design: Part of Nichicon’s MUSE acoustic series and explicitly suited for audio signal circuits, aligning component selection with audio performance goals.
• Bi‑Polar Configuration: Provides polarity flexibility required for AC‑centred audio signal applications without capacitor polarity constraints.
• Compact Footprint: φ12.5 mm × 20 mm can and 5 mm lead spacing minimize board area while retaining 330 μF capacitance.
• Validated Endurance: Rated endurance of 1000 hours at 85°C with specified recovery characteristics for capacitance, tan δ, and leakage current supports predictable lifecycle behavior under rated stress.
• Regulatory Compliance: RoHS compliance simplifies selection for designs requiring restricted‑substance conformance.
