It is a radial lead, polarized can capacitor optimized for audio‑oriented circuits using Nichicon’s etching techniques to influence tonal characteristics.

Key value propositions include audio‑focused construction and practical electrical robustness: 2.2 mF capacitance at 25 V rating, RoHS compliance, and specified ripple handling for both low and high frequency audio applications.

Key Features

• Capacitance & Voltage — 2.2 mF capacitance with a 25 V rated voltage and ±20% tolerance, suitable for coupling, decoupling and power reservoir roles in audio circuits.
• Audio‑Grade Construction — Part of the UFG "Fine Gold" MUSE acoustic series using advanced etching techniques; specified in product literature as suited for high‑grade audio equipment and AV systems.
• Electrical Performance — Low‑frequency ripple current of 1.57 A at 120 Hz and high‑frequency ripple current of 1.806 A at 10 kHz, providing defined ripple handling across audio band and switching noise spectra.
• Loss and Leakage Characteristics — Specified tangent of loss angle (tan δ) for the series (0.14 max. at 25 V, 120 Hz, 20°C) and leakage current defined in the datasheet (0.01CV or 3 μA, whichever is greater after 1 minute at 20°C).
• Thermal & Lifetime Ratings — Operating temperature range −40°C to +85°C with endurance rated at 1000 hours at 85°C, enabling reliable operation in typical consumer and professional audio environments.
• Package & Mounting — Radial lead, can package with 7.5 mm lead spacing; physical dimensions L: 3.55 × D: 1.6 cm and maximum seated height 1.398 inch for PCB planning.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑Grade Audio Equipment — Use in amplifier circuits, preamplifiers and signal path networks where the UFG series’ acoustic tuning is specified for sonic character.
• AV Systems — Suitable for audiovisual components requiring robust decoupling and reservoir capacitance at audio‑relevant frequencies.
• Power Supply Filtering — Employed as power smoothing and ripple suppression capacitors in audio power rails, leveraging specified ripple current ratings.
• General Purpose Audio Electronics — Radial lead form factor fits through‑hole PCB designs in consumer and professional audio gear where polarized electrolytic capacitors are required.

Unique Advantages

• Audio‑Focused Design: Part of the "Fine Gold" MUSE acoustic series and built with etching techniques the series documentation identifies as suited to richer bass and clearer high end.
• Defined Ripple Handling: Ripple current ratings at 120 Hz and 10 kHz provide measurable performance data for designers addressing both low‑frequency power ripple and higher frequency switching noise.
• Robust Temperature and Endurance: −40°C to +85°C operating range with 1000 hours endurance at 85°C supports sustained operation in typical audio electronics environments.
• Radial Can Convenience: Standard radial lead, can package with 7.5 mm lead spacing and compact footprint (L: 3.55 × D: 1.6 cm) simplifies through‑hole assembly and retrofitting in audio PCBs.
• Regulatory Compliance: RoHS compliance supports deployment in products that must meet current European hazardous‑substance restrictions.
