UFG1V222MHM

The UFG1V222MHM is a high‑grade aluminum electrolytic capacitor from Nichicon's UFG "Fine Gold" MUSE acoustic series, designed specifically for high‑grade audio and AV equipment. It is a polarized, radial‑lead can intended for general purpose use in audio circuits where a rich bass response and clearer high end are desired.

Key electrical and mechanical characteristics include 2.2 mF capacitance at 35 V, radial lead mounting with 7.5 mm lead spacing, RoHS compliance, and specified ripple current ratings for both low and high frequency operation.

Key Features

• Audio‑tuned "Fine Gold" MUSE series — Engineered for high‑grade audio and AV applications using specialized etching techniques to deliver rich bass and clearer high‑end reproduction.
• Capacitance and voltage — 2.2 mF capacitance rated at 35 V for energy storage and decoupling in audio power and signal circuits.
• Package and mounting — Radial can package with radial lead mounting and 7.5 mm lead spacing for through‑hole PCB layouts.
• Operating range and endurance — Rated for operation from −40 °C to +85 °C with a specified lifetime of 1000 hours at 85 °C.
• Ripple current capability — 1.84 A at 120 Hz and 2.116 A at 10 kHz, supporting both low‑frequency smoothing and higher‑frequency ripple handling.
• Tolerance and polarization — Capacitance tolerance −20% to +20%; polarized device for correct orientation in DC circuits.
• Leakage current specification — After 1 minute's application of rated voltage at 20 °C, leakage current is not more than 0.01CV or 3 µA, whichever is greater (per datasheet).
• RoHS compliance — Meets the RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.
• Physical dimensions — Compact radial can with dimensions L: 3.55 × D: 1.8 cm and a lead spacing of 7.5 mm.
• Loss tangent (tan δ) — Maximum tan δ of 0.12 at the 35 V rating (measured at 120 Hz, 20 °C) as specified in the series datasheet.

Typical Applications

• High‑grade Audio Equipment — Used in amplifiers, preamplifiers, and other audio circuits to support improved bass response and clearer high frequencies as part of power or signal path filtering.
• AV Equipment — Suited for home theater and AV electronics where audible performance is a priority and robust ripple handling is required.
• General Purpose Electronics — Applicable to general purpose DC smoothing and decoupling in consumer and professional electronic products that benefit from a high‑grade acoustic series capacitor.

Unique Advantages

• Audio‑oriented acoustic design: The "Fine Gold" MUSE series construction targets audible improvements—richer bass and clearer highs—making it appropriate for audio‑centric designs.
• Balanced ripple performance: Specified ripple current values at both 120 Hz and 10 kHz support effective smoothing across low and high frequency components of power rails.
• Robust temperature and life rating: −40 °C to +85 °C operating range with 1000 hours endurance at 85 °C provides predictable performance in typical audio equipment environments.
• Measured electrical characteristics: Defined leakage current limits and tan δ values (per datasheet) allow designers to estimate losses and idle current precisely.
• Standard radial form factor: Through‑hole radial can with 7.5 mm lead spacing simplifies prototyping and replacement in legacy and new board designs.
• Regulatory compliance: RoHS conformity supports environmental requirements for commercial and consumer electronics.
