UES1H470MPM

The UES1H470MPM is a bi‑polar aluminum electrolytic capacitor from Nichicon’s UES "MUSE" acoustic series, engineered for audio signal circuits. This radial‑lead, through‑hole can provides 47 µF capacitance at a 50 V rating and is RoHS compliant.

Designed for audio equipment, the part combines a bipolar topology with specifications aimed at stable signal performance across a wide temperature range and established endurance parameters for reliable long‑term use.

Key Features

• Capacitance & Voltage — 47 µF rated capacitance with a 50 V voltage rating, suitable for AC‑coupling and signal path uses in audio circuits.
• Bi‑polarized Design — Bi‑polar (non‑polar) construction intended for AC signal applications common in audio equipment.
• Package & Mounting — Radial lead, can‑style package for through‑hole mounting; lead spacing 5 mm and physical dimensions L: 2 cm × D: 1 cm.
• Temperature Range — Operating temperature −40 °C to +85 °C, supporting a broad range of environmental conditions for consumer and professional audio gear.
• Endurance — Rated for 1000 hours at 85 °C with polarity inversion every 250 hours; capacitance change remains within ±20% after the endurance test.
• Electrical Stability — Low dissipation factor with tan δ ≤ 0.12 (for 50 V, measured at 120 Hz, 20 °C) and defined low‑temperature impedance ratios (Z(−25 °C)/Z(+20 °C) ≤ 2; Z(−40 °C)/Z(+20 °C) ≤ 4).
• Leakage Current — Specified leakage current not more than 0.03CV (µA) after one minute’s application of rated voltage at 20 °C, per the datasheet.
• Tolerance & Compliance — Capacitance tolerance ±20% and compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio signal coupling — Ideal for AC‑coupling and signal path components in audio equipment where a bi‑polar capacitor is required.
• Audio processing circuits — Suited for use in preamplifier and processing stages that demand stable capacitance and low dissipation.
• Consumer and professional audio devices — Intended for integration in amplifiers, mixers, and other audio products within the operating temperature and endurance specifications.

Unique Advantages

• Audio‑focused bipolar topology — Specifically produced as part of Nichicon’s MUSE acoustic series and suited to audio signal circuits, reducing the need to adapt polarized components for AC paths.
• Through‑hole radial can package — Robust mechanical mounting and easy prototyping or board‑level replacement in audio assemblies.
• Defined high‑temperature endurance — 1000 hours at 85 °C (with periodic polarity inversion) gives predictable long‑term behavior for thermal stress scenarios.
• Measured electrical stability — Low tan δ at 50 V (≤ 0.12 at 120 Hz, 20 °C) and controlled low‑temperature impedance ratios support consistent audio performance across temperatures.
• Regulatory compliance — RoHS compliant for designs that require restricted substance adherence.
