UES1V4R7MDM

The UES1V4R7MDM is a bi‑polarized aluminum electrolytic capacitor from Nichicon's UES "MUSE" acoustic series, engineered for audio signal circuits. It is a radial‑lead, can‑style capacitor specified at 4.7 µF and 35 V with a compact footprint for board‑level audio applications.

Designed for audio use and RoHS compliant, the part combines audio‑focused series characteristics with documented electrical and environmental performance across an operating temperature range of ‑40 °C to +85 °C and a rated lifetime of 1000 hours at 85 °C.

Key Features

• Capacitance & Tolerance — 4.7 µF nominal capacitance with tolerance of ‑20% to +20% (at 120 Hz, 20 °C).
• Rated Voltage — 35 V working voltage suitable for audio signal applications within the specified voltage class.
• Bi‑Polarized Audio Series — Part of Nichicon's MUSE acoustic UES series, explicitly suited for audio signal circuits and provided as a bi‑polarized component.
• Electrical Loss & Leakage — Tangent of loss angle (tan δ) for 35 V is specified at 0.14 (measurement frequency: 120 Hz at 20 °C); leakage current is specified as not more than 0.03 × C × V (µA) after one minute at 20 °C.
• Low‑Temperature Stability — Impedance stability ratios are specified: Z(‑25 °C)/Z(+20 °C) = 2 and Z(‑40 °C)/Z(+20 °C) = 4, supporting consistent behavior across the rated temperature range.
• Endurance & Shelf Life — Meets endurance requirements after 1000 hours at 85 °C with polarity inversion every 250 hours: capacitance change within ±20%, tan δ ≤ 150% of initial spec, and leakage current ≤ initial specified value; equivalent shelf‑life conditioning is specified after 1000 hours at 85 °C.
• Package & Mounting — Radial lead, can package with lead spacing of 2.0 mm and physical size L: 1.1 cm × D: 0.5 cm; height seated max 1.1 cm.
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Signal Circuits — Suited for use in audio signal paths where a bi‑polarized capacitor is required for AC or alternating audio signals.
• High‑fidelity Audio Components — Applicable in audio equipment stages that reference Nichicon's MUSE acoustic series for signal conditioning and coupling.
• Board‑Level Radial Installations — Compact radial can footprint for through‑hole mounting in compact audio PCBs and assemblies.

Unique Advantages

• Audio‑focused series — Part of Nichicon’s MUSE acoustic lineup, explicitly positioned for audio signal circuit use.
• Bi‑polarized construction — Designed for applications where capacitance must tolerate polarity inversion as demonstrated in the endurance test procedure.
• Measured electrical parameters — Specified tan δ (0.14 at 35 V, 120 Hz, 20 °C) and defined leakage current limit (≤0.03CV after 1 minute) provide quantifiable electrical behavior for design verification.
• Wide operating temperature — Rated for ‑40 °C to +85 °C operation, supporting a range of audio environments.
• Documented endurance — Endurance and shelf‑life conditions (1000 hours at 85 °C with polarity inversion) provide a clear baseline for reliability planning.
• RoHS compliant — Conforms to 2011/65/EU and (EU)2015/863 requirements for restricted substances.
