UES1V221MHM

The UES1V221MHM is a bi‑polarized aluminum electrolytic capacitor from Nichicon’s MUSE acoustic series, designed specifically for audio signal circuits. It provides a 220 µF capacitance at a 35 V rated voltage in a radial‑lead can package suitable for board‑level audio assemblies.

Built for audio applications, the part combines bi‑polar construction with series‑level specifications—including RoHS compliance, an operating temperature range of –40 to +85 °C, and specified endurance testing—to support reliable performance in acoustic electronics.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 35 V rated voltage, suitable for signal‑path and circuit applications that require this capacitance/voltage point.
• Bi‑Polarized Audio Design — Bi‑polar construction from the Nichicon MUSE acoustic series, explicitly suited for audio signal circuits where non‑polar behavior is required.
• Tolerance & Stability — Capacitance tolerance of ±20% (at 120 Hz, 20 °C); series stability characteristics include defined impedance ratios at low temperatures (Z(–25 °C)/Z(+20 °C) ≤ 2, Z(–40 °C)/Z(+20 °C) ≤ 4).
• Loss & Leakage — Tangent of loss angle (tan δ) for the 35 V rating is specified (max. 0.14). Leakage current is specified by the series as not more than 0.03CV (µA) after 1 minute’s application of rated voltage at 20 °C.
• Mechanical & Mounting — Radial lead, can‑style package with 5 mm lead spacing and physical dimensions L: 2.5 × D: 1.25 cm for straightforward through‑hole mounting.
• Thermal Endurance — Operating temperature range of –40 to +85 °C with an endurance characterization of 1000 hours at 85 °C (test includes polarity inversion schedule per datasheet).
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio signal circuits — Designed for use in signal paths where bi‑polarized capacitors are required to handle AC audio signals.
• Professional and consumer audio equipment — Suited for board‑level implementations in amplifiers, preamps, and other acoustic electronics that leverage the MUSE acoustic series.
• Acoustic modules and assemblies — Appropriate for modular audio designs that require radial‑lead components for through‑hole assembly.

Unique Advantages

• Bi‑polarized construction: Enables use in AC‑coupled audio signal paths without polarity constraints, matching the needs of many audio circuit topologies.
• Audio‑focused series: Part of the Nichicon MUSE acoustic series, explicitly intended for audio applications, aligning product selection with acoustic design goals.
• Defined electrical performance: Specified tan δ and leakage current limits allow predictable behavior for designers tuning frequency response and noise characteristics.
• Temperature and endurance characterization: Rated for –40 to +85 °C with endurance data (1000 h at 85 °C) to support lifecycle planning in typical audio environments.
• Through‑hole mounting convenience: Radial lead, can package with 5 mm lead spacing simplifies prototyping and replacement in board‑level audio designs.
• RoHS compliant: Meets applicable RoHS directives for applications that require restricted‑substance compliance.
