UES1E221MHM

The UES1E221MHM is a bi‑polarized aluminum electrolytic capacitor from Nichicon’s UES "MUSE" acoustic series, engineered specifically for audio signal circuits. It delivers 220 µF at 25 V in a compact radial can package suited to analog audio equipment where AC‑capable coupling and decoupling are required.

Designed for acoustic and audio equipment applications, the component combines a bi‑polarized construction with documented endurance and temperature performance to support reliable operation in signal paths and other audio circuitry.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance at a rated voltage of 25 V, with tolerance ±20% (–20% to +20%).
• Bi‑polarized Audio Design — Part of the "nichicon MUSE" acoustic series and explicitly suited for audio signal circuits, enabling use in AC‑coupled audio paths.
• Mechanical / Package — Radial lead, can‑style package with lead spacing 5 mm and physical size L: 2.5 cm × D: 1.25 cm for compact board placement.
• Temperature Range — Rated to operate from –40 °C to +85 °C to accommodate a broad range of ambient conditions.
• Endurance & Reliability — Specified lifetime of 1000 hours at 85 °C with polarity inversion (per datasheet endurance test); capacitance change and leakage are defined after this test.
• Electrical Loss & Leakage — Low loss characteristics with tan δ up to 0.16 at 25 V (measured at 120 Hz, 20 °C) and leakage current specified as ≤ 0.03CV (µA) after one minute at 20 °C.
• Regulatory — Compliant with the RoHS directive (2011/65/EU and (EU)2015/863).
• Marking — Identified with black printed lettering on a clear green sleeve for easy visual verification.

Typical Applications

• Audio signal coupling and decoupling — Intended for use in AC‑coupled signal paths where a bi‑polarized capacitor is required to handle alternating audio waveforms.
• Analog audio equipment — Suited to amplifiers, preamplifiers and other acoustic circuits that benefit from a capacitor designed for audio performance.
• Studio and consumer audio devices — Use in signal stages of mixers, headphone amplifiers and line‑level stages where compact, audio‑grade capacitors are needed.

Unique Advantages

• Audio‑focused design: Part of Nichicon’s MUSE acoustic series and explicitly specified for audio signal circuits, providing a component tailored to audio applications.
• Bi‑polarized capability: Enables safe operation in AC and polarity‑reversing conditions common in signal coupling and certain audio circuits.
• Compact radial can package: 2.5 cm × 1.25 cm footprint with 5 mm lead spacing supports space‑constrained board designs without sacrificing capacitance.
• Defined endurance profile: Rated for 1000 hours at 85 °C with polarity inversion testing, giving clear, verifiable expectations for long‑term behavior under stress.
• Low leakage and controlled dissipation: Leakage current specified as ≤ 0.03CV (µA) and tan δ specified (0.16 at 25 V), supporting low‑noise analog performance.
• RoHS compliant: Meets modern regulatory requirements (2011/65/EU, (EU)2015/863) for material content.
