UES1A470MEM

The UES1A470MEM is a bi-polarized aluminum electrolytic capacitor from Nichicon's MUSE acoustic series, engineered for use in audio signal circuits and audio equipment. Its bi-polar construction and radial-can package make it suitable for AC audio paths where non-polar operation and reliable audio performance are required.

Designed for compact audio designs, the UES1A470MEM combines a 47 µF capacitance with a 10 V rated voltage, radial lead mounting, and a compact footprint to support signal-level filtering and coupling in consumer and professional audio products.

Key Features

• Bi-Polarized Audio Design  Bi-polarized construction from the "nichicon MUSE" acoustic series, suited for audio signal circuits and audio equipment applications.
• Capacitance & Voltage  47 µF nominal capacitance with a 10 V rated voltage, providing the capacitance value commonly used in signal-level audio paths.
• Tolerance  ±20% capacitance tolerance (measured at 120 Hz, 20 °C), specified for predictable performance in design.
• Package & Mounting  Radial lead, can-style package with a 2.5 mm lead spacing for through-hole mounting and straightforward PCB placement.
• Operating Temperature  Rated for operation from –40 °C to +85 °C, covering typical ambient conditions for audio electronics.
• Endurance  Specified endurance of 1000 hours at 85 °C with polarity inversion cycles as defined by the series specification.
• Compact Dimensions  Compact radial can size with dimensions approximately 1.1 × 0.63 cm (length × diameter), suitable for space-constrained audio assemblies.
• RoHS Compliant  Conforms to the RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory requirements for lead-free assemblies.

Typical Applications

• Line-level audio circuits  Used in line-level signal paths where bi-polar capacitors are required for AC audio coupling and signal integrity.
• Audio equipment front-ends  Suited for front-end circuits in audio equipment that require non-polar electrolytics for balanced or AC-coupled stages.
• Signal coupling and filtering  Employed in signal coupling and low-frequency filtering tasks within consumer and professional audio products.

Unique Advantages

• Audio-focused MUSE series design: The MUSE acoustic series designation signals design intent for audio signal applications, aligning the component with audio-focused circuit requirements.
• Bi-polar construction for AC operation: Eliminates polarity restrictions in AC-coupled audio paths, simplifying design for balanced or alternating signal conditions.
• Compact radial-can footprint: Small physical dimensions and 2.5 mm lead spacing enable dense PCB layouts and easy through-hole assembly.
• Robust temperature and endurance specs: Rated for −40 °C to +85 °C with 1000 hours endurance at 85 °C, providing predictable lifetime behavior under specified stress conditions.
• Regulatory compliance: RoHS compliance supports deployment in products requiring lead-free components and adherence to EU directives.
• Predictable leakage behavior: Series leakage current specification (≤0.03CV µA after 1 minute at 20 °C) provides a measurable baseline for design margining.
