UFG1A221MPM

The UFG1A221MPM is a high‑grade aluminum electrolytic capacitor from Nichicon’s UFG "Fine Gold" MUSE acoustic series, engineered for audio and AV equipment. It is a radial lead, polarized can capacitor optimized for audio applications where bass richness and clearer high end are desired, using state‑of‑the‑art etching techniques.

Designed for general‑purpose use in audio circuitry, the part combines compact packaging with defined electrical performance, RoHS compliance, and published endurance and ripple specifications for reliable operation in consumer and professional AV designs.

Key Features

• Audio‑focused series: Part of Nichicon’s UFG "Fine Gold" MUSE acoustic series, specified to produce richer bass register and clearer high end for AV and high‑grade audio equipment.
• Electrical rating: 220 µF capacitance at 10 V with ±20% tolerance (measured at 120 Hz, 20°C), suitable for typical audio power and decoupling roles.
• Low loss angle (tan δ): Specified tan δ max of 0.19 at 10 V (measured at 120 Hz, 20°C), supporting stable AC performance in audio frequency ranges.
• Ripple current capability: Rated ripple current of 170 mA at 120 Hz and 255 mA at 10 kHz, providing quantifiable filtering performance for power rails and decoupling.
• Operational range and endurance: Operating temperature −40°C to +85°C with a rated lifetime of 1000 hours at 85°C, and defined endurance recovery characteristics after the test.
• Polarized radial can package: Radial lead, can package with 3.5 mm lead spacing and compact dimensions (L: 1.15 × D: 0.8 cm), offering an easy mechanical footprint for through‑hole audio PCBs.
• Manufacturing and marking: Gold sleeve with black printed marking; manufactured by Nichicon and compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade audio equipment: Coupling, decoupling and power supply smoothing in amplifiers, preamplifiers and other high‑fidelity audio circuits where tonal character is important.
• AV receivers and components: Filtering and supply stabilization in AV systems to support cleaner high end and fuller bass reproduction.
• General purpose audio electronics: PCB through‑hole implementations requiring compact radial capacitors for power rail decoupling and signal path conditioning.

Unique Advantages

• Audio‑tuned acoustic series: The "Fine Gold" MUSE designation and etching techniques are specified to influence tonal characteristics—providing design differentiation for audio products.
• Quantified ripple handling: Published ripple current values at both low (120 Hz) and high (10 kHz) frequencies allow predictable filtering performance in power and audio paths.
• Compact radial form factor: Small can dimensions and 3.5 mm lead spacing simplify PCB layout in space‑constrained through‑hole designs.
• Defined endurance data: Rated for 1000 hours at 85°C with specified post‑test limits for capacitance, tan δ and leakage, supporting reliability planning for product lifecycles.
• Regulatory compliance: RoHS compliant per provided directives, enabling use in regions requiring restriction of certain hazardous substances.
• Consistent identification: Gold sleeve with black printed marking provides clear part identification on assembled boards.
