UES1A471MHM

The UES1A471MHM is a bi‑polar aluminum electrolytic capacitor from Nichicon’s UES "MUSE" acoustic series, designed specifically for audio signal circuits. Its construction and ratings make it suitable for through‑hole audio assemblies that require AC‑capable coupling capacitors with a compact radial can package.

Key value comes from its bi‑polar design for audio signal paths, a 470 µF capacitance at 10 V rating for substantial AC coupling, RoHS compliance, and endurance specified for extended operation up to 85°C.

Key Features

• Bi‑Polar Design Enables AC coupling in audio signal circuits without polarity constraints, suited for applications where signal polarity can reverse.
• Capacitance and Voltage 470 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance, providing bulk capacitance for line‑level and coupling applications.
• Package and Mounting Radial lead, can‑style package with 5 mm lead spacing and a compact size of L: 2 cm × D: 1.25 cm for through‑hole PCB assembly.
• Temperature and Endurance Operational range –40°C to +85°C with an endurance rating of 1000 hours at 85°C (capacitance, tan δ and leakage requirements defined after test conditions).
• Leakage Characteristic Series leakage specification: after 1 minute’s application of rated voltage at 20°C, leakage current is not more than 0.03CV (µA), supporting predictable behavior in precision audio paths.
• RoHS Compliance Conforms to the RoHS directive (2011/65/EU, (EU)2015/863), meeting environmental regulatory requirements for restricted substances.
• Marking Part is printed with black lettering on a clear green sleeve for straightforward identification on finished assemblies.

Typical Applications

• Audio signal circuits — Suited for AC coupling and signal path filtering in audio electronics where bi‑polar capacitance is required.
• Preamp and line‑level stages — Provides bulk coupling capacitance for through‑hole designs in consumer and pro audio equipment.
• Through‑hole PCB assemblies — Radial lead form and 5 mm lead spacing facilitate mounting in traditional PCB layouts and retrofit designs.

Unique Advantages

• Bi‑polar operation: Eliminates polarity concerns in AC signal paths, simplifying circuit design for audio coupling and signal processing.
• High capacitance in a compact can: 470 µF in a 2.0 cm × 1.25 cm envelope delivers substantial charge storage while minimizing board space.
• Engineered for audio: Part of Nichicon’s MUSE acoustic series, intended for use in audio signal circuits.
• Predictable leakage behavior: Leakage current bounded by 0.03CV (µA) after 1 minute at 20°C supports consistent performance in sensitive audio paths.
• Designed for elevated temperature endurance: Rated for 1000 hours at 85°C, giving designers a clear thermal endurance specification for reliability planning.
• Regulatory compliance: RoHS conformity reduces material compliance burden for product development and procurement.
