UES1H220MPM

The UES1H220MPM is a bi‑polarized aluminum electrolytic capacitor from Nichicon’s MUSE acoustic series, engineered for audio signal circuits. It is a radial‑lead, can‑style capacitor providing 22 µF capacitance at a 50 V rating with RoHS compliance.

Designed for signal‑path use, the component combines a compact radial package (φD × L = 10 mm × 12.5 mm) and audio‑focused construction with defined endurance and temperature performance for reliable operation in audio equipment.

Key Features

• Capacitance & Voltage — 22 µF rated capacitance at 50 V, with a tolerance of ±20% (measured at 120 Hz, 20°C).
• Bi‑Polar Construction — Bi‑polarized design suited for AC‑coupling and audio signal paths where polarity reversal may occur.
• Audio‑Focused Series — Part of Nichicon’s MUSE acoustic series, explicitly suited for audio signal circuits.
• Package & Mounting — Radial lead, can package with lead spacing of 5 mm and physical size L: 12.5 mm × D: 10 mm for through‑hole PCB mounting.
• Operating Range & Reliability — Rated for –40°C to +85°C operating temperature and specified for 1000 hours at 85°C with polarity inversion every 250 hours (endurance conditions).
• Leakage & Loss Characteristics — Leakage current specified as not more than 0.03CV (µA) after 1 minute’s application of rated voltage at 20°C; tangent of loss angle (tan δ) for 50 V is 0.12 maximum (measured at 120 Hz, 20°C).
• Low‑Temperature Stability — Impedance ratios vs. +20°C: Z(–25°C)/Z(+20°C) = 2 and Z(–40°C)/Z(+20°C) = 4, supporting stable performance across audio operating temperatures.
• RoHS Compliant — Compliant with RoHS directives (2011/65/EU and (EU)2015/863).

Typical Applications

• Audio signal coupling/decoupling — Use in input/output stages and between amplifier stages where a bi‑polar capacitor is required for AC coupling.
• Preamp and signal‑path circuits — Suited for small‑signal circuits in preamplifiers and mixing equipment within the stated temperature range.
• Loudspeaker crossovers and filters — Applicable to passive filter sections in speaker systems where compact radial components are needed.
• Studio and pro audio equipment — Designed for use in signal‑critical paths of professional audio devices that require defined endurance and low leakage.

Unique Advantages

• Audio‑centric design: Part of the Nichicon MUSE acoustic series and specified for audio signal circuits, aligning the component’s characteristics with signal‑path requirements.
• Bi‑polar flexibility: Bi‑polarized construction permits use in circuits with AC or reversing polarity without the constraints of a single‑polarity electrolytic.
• Compact, through‑hole form factor: Radial can package with 5 mm lead spacing and a 10 mm × 12.5 mm footprint simplifies PCB layout for legacy and repairable audio equipment.
• Measured electrical limits: Defined leakage current limit (0.03CV µA after 1 minute at 20°C) and a specified tan δ (0.12 max at 50 V, 120 Hz) for predictable signal performance.
• Temperature and endurance specification: Rated –40°C to +85°C with a 1000‑hour endurance test at 85°C (with polarity inversion), giving a clear reliability baseline for design planning.
• Regulatory compliance: RoHS conformance supports use in designs requiring restriction of hazardous substances.
