UES1E102MHM

The UES1E102MHM is a bi‑polar aluminum electrolytic capacitor from Nichicon's MUSE acoustic series, specifically designed for audio signal circuits. This radial‑lead, bi‑polar can provides high capacitance in a package tailored for audio applications and is RoHS compliant.

Key Features

• Bi‑Polarized Audio Design Bi‑polar construction intended for use in audio signal circuits where polarity reversal may occur.
• High Capacitance at 25 V 1 mF (1000 μF) rated capacitance at 25 V, suitable where substantial signal coupling or energy storage is required.
• Electrical Performance Maximum tan δ of 0.16 (measured at 120 Hz, 20 °C) and specified leakage current of 750 μA (measured at 20 °C after 1 minute) for this part number.
• Temperature and Endurance Operating range −40 °C to +85 °C with endurance tested to 1000 hours at 85 °C (capacitance change within ±20% after test with polarity inversion every 250 hours).
• Radial Lead Package Radial can with 7.5 mm lead spacing, footprint friendly for through‑hole PCB layouts; case dimensions φ16 × 30.5 mm (L: 30.5 mm × D: 16 mm / L: 3.05 × D: 1.6 cm).
• RoHS Compliant Conforms to the RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory requirements for lead‑free designs.

Typical Applications

• Audio signal circuits — Intended for use in audio signal paths where bi‑polar capacitors are required.
• Audio signal coupling — Suitable for AC‑coupling and signal conditioning stages in audio equipment.
• Pro and consumer audio devices — Applicable in acoustic‑focused designs within professional and consumer audio systems.

Unique Advantages

• Bi‑polar design for AC audio use: Enables operation in circuits with alternating polarities without requiring explicit polarity orientation.
• Large capacitance at modest voltage: 1 mF at 25 V provides substantial charge storage for audio signal conditioning and coupling tasks.
• Audio‑oriented series: Part of Nichicon’s MUSE acoustic lineup, positioned for audio applications where component selection targets acoustic performance.
• Engineered endurance: Rated for 1000 hours at 85 °C with defined post‑test limits (capacitance within ±20%), supporting reliability in elevated‑temperature deployments.
• Clear footprint and mounting: Radial can with 7.5 mm lead spacing and φ16 × 30.5 mm case simplifies through‑hole PCB integration and mechanical placement.
• Regulatory compliance: RoHS compliant to the stated directives, aiding designs requiring restricted‑substance conformance.
