UES1C221MPM

The UES1C221MPM from Nichicon is a bi‑polarized aluminum electrolytic capacitor in the UES "MUSE" acoustic series, designed specifically for audio signal circuits. Its construction and electrical characteristics make it suitable for AC‑coupling and signal‑path applications where low loss and predictable behavior across temperature are important.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance at a rated voltage of 16 V, with ±20% tolerance for predictable signal coupling.
• Bi‑Polar Design for Audio — Bi‑polarized construction tailored for audio signal circuits and AC applications in the signal path.
• Low Loss (tan δ) — Specified tan δ of 0.16 at 16 V (measurement at 120 Hz, 20°C), supporting low dissipation in audio paths.
• Leakage Current — Leakage current specified as 105.6 µA (measured at 20°C after 1 minute for this part), enabling controlled DC characteristics in coupling applications.
• Operating Temperature & Endurance — Rated for −40°C to +85°C. Endurance defined as 1000 hours at 85°C with the polarity inverted every 250 hours; capacitance change remains within ±20% after the endurance test.
• Radial Lead Can Package — Radial, can-style package with 5 mm lead spacing and radial lead mounting for through‑hole PCB designs.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Signal Paths — AC coupling and DC blocking in preamplifiers, mixers, and line‑level circuits where bi‑polar performance is required.
• Preamplifiers and Instrumentation — Use in input/output stages of audio preamps and instrument amplifiers to preserve signal integrity.
• Hi‑Fi and Consumer Audio Equipment — Signal‑chain coupling and tone‑control circuits in hi‑fi systems and audio peripherals.

Unique Advantages

• Audio‑Focused Bi‑Polar Construction: Enables AC signal handling without polarity constraints, simplifying coupling networks in audio designs.
• Measured Low Loss: A tan δ of 0.16 at 16 V supports lower dissipation in the signal path for consistent audio performance.
• Defined Leakage Behavior: Part‑specific leakage current specification (105.6 µA at 20°C, 1 minute) helps designers predict DC bias in coupling circuits.
• High‑temperature Endurance: Rated 1000 hours at 85°C with defined post‑test limits (capacitance within ±20%), supporting reliability assessments for product lifetimes.
• Through‑Hole Radial Mounting: Radial can package with 5 mm lead spacing simplifies prototyping and through‑hole assembly for legacy and robust PCB layouts.
• Regulatory Compliance: RoHS compliance supports use in electronics that require restricted‑substance conformance.
