UES1C220MEM

The UES1C220MEM is a bi‑polar aluminum electrolytic capacitor from Nichicon's UES (MUSE acoustic) series, designed specifically for audio applications. Its construction and specifications target audio signal circuitry where bi‑polar operation and reliable performance across a wide temperature range are required.

This radial‑lead, can‑style capacitor combines a 22 µF capacitance with a 16 V rating, compact dimensions, and audio‑focused characteristics suitable for use in audio equipment and signal paths.

Key Features

• Bi‑Polar Acoustic Series Part of Nichicon’s MUSE acoustic UES series; specified for audio use and suited for audio signal circuits.
• Capacitance & Voltage 22 µF nominal capacitance at a rated voltage of 16 V with ±20% tolerance.
• Electrical Performance Tangent of loss angle (tan δ) max 0.16 (measured at 120 Hz, 20°C for 16 V rating). Leakage current after 1 minute at 20°C is limited by the datasheet formula (≤ 0.03·C·V), which corresponds to ≤ 10.56 µA for this 22 µF, 16 V part.
• Low‑temperature Stability Impedance ratios relative to +20°C: Z(–25°C)/Z(+20°C) = 2 and Z(–40°C)/Z(+20°C) = 4 (specified at 16 V rating).
• Package & Mounting Radial lead, can package with lead spacing 2.5 mm and physical size L: 1.1 × D: 0.63 cm for compact board placement.
• Operating Range & Endurance Rated for –40°C to +85°C. Endurance: meets specified characteristics after 1000 hours at 85°C with polarity inverted every 250 hours (capacitance change within ±20%, tan δ ≤ 150% of initial specified value, leakage current ≤ initial specified value).
• Identification Marked with black printing on a clear green sleeve for easy visual identification.

Typical Applications

• Audio equipment — Suited for use in audio equipment signal paths where bi‑polarized electrolytic capacitors are required.
• Audio signal circuits — Designed specifically for audio signal circuit use as noted in the product series description.
• Acoustic electronics — Appropriate for acoustic and sound‑focused electronics that specify MUSE acoustic series components.

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 construction: Permits AC‑coupled or polarity‑reversing conditions typical in audio paths without polarity constraints of standard polarized capacitors.
• Compact radial can package: Small footprint (L: 1.1 × D: 0.63 cm) and 2.5 mm lead spacing support dense board layouts and through‑hole mounting.
• Measurable electrical limits: Specified tan δ (0.16 max at 16 V) and a defined leakage current formula provide predictable electrical behavior for design verification.
• Temperature and endurance data: Specified operating range of –40°C to +85°C and 1000 hours endurance at 85°C with defined post‑test limits aid reliability planning.
• Clear identification: Black printing on a clear green sleeve simplifies assembly and inspection.
