UFG1H4R7MDM

The UFG1H4R7MDM is a Nichicon UFG series aluminum electrolytic capacitor designed for high-grade audio and AV equipment. It is a radial-lead, polarized can-type capacitor from the "Fine Gold" MUSE acoustic series, engineered with etching techniques to support richer bass and clearer high-end audio reproduction.

This unit provides 4.7 µF capacitance at a 50 V rating, compact radial packaging, and operating capability across −40°C to +85°C, making it suitable for a range of audio circuit applications requiring compact, audio-oriented filtering and decoupling.

Key Features

• Audio-Grade MUSE "Fine Gold" Series Designed for high-grade audio equipment with etching techniques intended to enhance bass richness and clarity in the high end.
• Electrical Specification 4.7 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• Ripple Performance Specified ripple current handling of 27 mA at 120 Hz and 54 mA at 10 kHz for low- and high-frequency applications.
• Thermal and Endurance Operating temperature range −40°C to +85°C with endurance specified as 1000 hours at 85°C under rated voltage.
• Compact Radial Package Radial, can-style package with lead spacing of 2 mm and physical size L: 1.1 × D: 0.5 cm for space-constrained boards.
• Polarized Design Conventional electrolytic polarization for DC supply filtering, coupling, and decoupling in audio circuits.
• RoHS Compliant Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• High-Fidelity Audio Components Ideal for coupling, decoupling, and power supply smoothing in preamplifiers, amplifiers, and other precision audio circuits where tonal balance is important.
• AV Receivers and Home Theater Suited for AV equipment power rails and audio signal paths to support clearer high-frequency detail and robust bass response.
• Consumer Audio Electronics Use in compact, board-mounted filtering roles in high-grade portable or stationary audio devices.

Unique Advantages

• Acoustic-focused Design: The "Fine Gold" MUSE acoustic series and specialized etching techniques target audible improvements—richer bass and clearer high end—useful in audio-centric designs.
• Small Footprint: Compact radial can dimensions (1.1 × 0.5 cm) with 2 mm lead spacing allow placement in tight layouts without sacrificing audio performance.
• Designed for Elevated Temperature Endurance: Rated for 1000 hours at 85°C under rated voltage, supporting reliable operation in sustained thermal conditions.
• Frequency Versatility: Specified ripple currents at both 120 Hz and 10 kHz provide data for designing across common audio power and signal frequencies.
• Regulatory Compliance: RoHS compliance supports use in environments requiring restricted substances conformity.
