UFG1K221MHM

The UFG1K221MHM is a Nichicon UFG-series aluminum electrolytic capacitor engineered for high‑grade audio and AV equipment. It is part of the "Fine Gold" MUSE acoustic lineup, which uses advanced etching techniques to deliver tuned audio characteristics for richer bass and clearer high frequencies.

This radial lead, polarized capacitor provides 220 µF capacitance at an 80 V rating, with general-purpose mounting and RoHS compliance for use in professional and consumer audio designs operating between -40 °C and 85 °C.

Key Features

• Audio‑focused design Part of the "Fine Gold" MUSE acoustic series; optimized for richer bass response and clearer high end in AV and audio equipment.
• Electrical characteristics Rated at 220 µF and 80 V with ±20% capacitance tolerance and polarized construction for DC filtering and signal coupling in audio circuits.
• Ripple handling Specified ripple current of 490 mA at 120 Hz and 735 mA at 10 kHz, supporting typical audio power-supply and signal-decoupling applications.
• Low‑loss performance (series data) Tangent of loss angle (tan δ) for the UFG series at the 80 V rating is specified up to 0.09 (measured at 120 Hz, 20 °C), indicating controlled dissipation for audio paths.
• Package & mounting Radial lead, can‑style package with 5 mm lead spacing and compact footprint (L: 2.5 × D: 1.25 cm) for through‑hole board mounting.
• Temperature & endurance Operating temperature range −40 °C to +85 °C with a rated endurance of 1000 hours at 85 °C under rated voltage.
• Regulatory Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑end AV equipment Used for power‑supply smoothing and coupling in home theater receivers, preamplifiers, and AV components where tuned audio character is desired.
• Audio amplifiers and crossovers Provides bulk capacitance and stable ripple handling for amplifier supply rails and passive/active crossover networks.
• Consumer audio electronics Suitable for use in CD players, DACs, and other consumer AV devices requiring reliable, audio‑oriented electrolytic capacitance.
• General‑purpose circuits Applicable where polarized aluminum electrolytic capacitors are required for decoupling, filtering, or energy storage in audio-centric designs.

Unique Advantages

• Acoustically tuned series: The "Fine Gold" MUSE acoustic formulation and etching techniques target richer bass and clearer highs—advantages that map directly to audible improvements in AV systems.
• High voltage rating: 80 V rating gives headroom for higher supply rails and power amplifier stages compared to lower‑voltage electrolytics.
• Measurable ripple capability: Defined ripple currents at both low and high frequencies (490 mA at 120 Hz, 735 mA at 10 kHz) support real-world audio power and signal conditions.
• Compact radial can package: Through‑hole radial lead format with a small footprint enables robust mounting and straightforward replacement or prototyping on standard PCBs.
• Operating and endurance ratings: −40 °C to +85 °C operating range with 1000 hours endurance at 85 °C provides predictable behavior over typical product lifecycles.
• RoHS compliance: Meets applicable RoHS directives for regulated materials, simplifying environmental compliance for finished products.
