UFG2A4R7MDM

The UFG2A4R7MDM is a 4.7 µF, 100 V polarized aluminum electrolytic capacitor from Nichicon’s UFG "Fine Gold" MUSE acoustic series, engineered for high‑grade audio and AV equipment. It is a radial‑lead, can‑style capacitor that combines audio‑focused etching techniques with specifications aimed at delivering stable performance across typical audio operating conditions.

Designed for general purpose and audio applications, this capacitor provides controlled loss characteristics, temperature stability down to −40 °C, and a 1000‑hour endurance at 85 °C for reliable performance in AV systems and related electronics.

Key Features

• Audio‑oriented construction Part of the "Fine Gold" MUSE acoustic series using state‑of‑the‑art etching techniques to emphasize richer bass and clearer high end for AV and audio equipment.
• Electrical rating 4.7 µF nominal capacitance at a rated voltage of 100 V with a capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• Polarized radial lead package Radial, can‑style construction with 2 mm lead spacing suitable for through‑hole PCB assembly and general‑purpose board-level audio circuits.
• Temperature and endurance Rated for operation from −40 °C to +85 °C with a specified endurance of 1000 hours at 85 °C with rated voltage applied.
• Low loss characteristics Maximum tan δ for 100 V rating is 0.08 (measured at 120 Hz, 20 °C), supporting lower dielectric losses in audio signal paths.
• Leakage current specification Series leakage current specification: after one minute at 20 °C and rated voltage, leakage ≤ 0.01CV or 3 µA (whichever is greater), supporting low bias current designs.
• Ripple handling Specified ripple current handling of 36 mA at 120 Hz and 72 mA at 10 kHz for use in applications with low to moderate AC ripple on DC rails.
• RoHS compliant Manufactured in compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade audio amplifiers — Used in signal coupling, decoupling, and power supply smoothing where audio character and stability are important.
• AV receivers and home theater — Suited for board‑level filtering and decoupling in AV equipment that benefits from the UFG series’ acoustic tuning.
• Preamplifiers and DAC circuits — Employed where low loss and controlled tonal response support accurate signal reproduction.

Unique Advantages

• Acoustically tuned series: The "Fine Gold" MUSE construction and etching techniques are specified to deliver a richer bass register and clearer high end, directly addressing audio system sonic goals.
• Compact radial form factor: Radial can package with 2 mm lead spacing and small footprint simplifies PCB placement for through‑hole audio designs.
• Wide operating temperature range: −40 °C to +85 °C rating ensures usable performance across typical consumer and professional AV environments.
• Documented endurance: 1000 hours at 85 °C with rated voltage provides a measurable reliability baseline for design planning.
• Measured electrical characteristics: Specified tan δ, leakage current behavior, and ripple current figures give engineers the data needed to assess noise, loss, and thermal loading in audio circuits.
• Regulatory compliance: RoHS compliance supports designs targeting markets with restricted substances requirements.
