UES1A101MPM

The UES1A101MPM is a bi-polar aluminum electrolytic capacitor from Nichicon’s UES MUSE acoustic series, designed specifically for audio equipment and audio signal circuits. Its bi-polarized design, compact radial-can package and RoHS compliance make it suitable for applications where reliable AC-coupled audio performance and compact board-level mounting are required.

This part provides 100 µF capacitance at a 10 V rating in a small radial-package footprint with 5 mm lead spacing, and is specified for operation from −40 °C to +85 °C with a rated life of 1000 hours at 85 °C.

Key Features

• Capacitance and Voltage: 100 µF capacitance with a 10 V rated voltage, suitable for signal-level audio applications that require stable capacitance in a low-voltage domain.
• Bi‑polar Construction: Bi-polarized (non-polar) design intended for audio signal circuits and other AC-coupled audio equipment applications.
• Package and Mounting: Radial lead, radial-can package with 5 mm lead spacing; compact dimensions L: 1.25 cm × D: 1.00 cm for space-constrained PCB layouts.
• Tolerance: Capacitance tolerance of −20% to +20% (±20%), specified at 120 Hz, 20 °C.
• Temperature and Lifetime: Operating temperature range −40 °C to +85 °C and rated lifetime of 1000 hours at 85 °C with polarity inversion endurance described in the UES series specification.
• RoHS Compliance: Compliant with applicable RoHS directives (2011/65/EU and (EU)2015/863).

Typical Applications

• Audio Signal Circuits: Intended for AC-coupling and signal-path use in audio equipment and related circuitry where bi-polarized capacitors are required.
• Audio Equipment: Suited for audio electronics within the Nichicon MUSE acoustic product family—where acoustic performance and signal integrity are priorities.
• Compact PCB Designs: Small radial-can footprint and 5 mm lead spacing make it practical for compact audio modules and assemblies requiring radial-leaded components.

Unique Advantages

• Audio-focused design: Part of Nichicon’s MUSE acoustic UES series, explicitly described for audio equipment and audio signal circuits.
• Bi‑polarized flexibility: Bi-polar construction supports use in circuits where signal polarity may vary, simplifying AC-coupling implementations.
• Compact radial package: Small dimensions (L: 1.25 cm × D: 1.00 cm) and 5 mm lead spacing enable dense board placement without sacrificing component robustness.
• Wide operating range: Rated for −40 °C to +85 °C operation, matching common environmental requirements for audio electronics.
• Defined reliability: Specified lifetime of 1000 hours at 85 °C with endurance conditions described in the UES series data, providing a clear reliability expectation for design planning.
• Regulatory compliance: RoHS-compliant construction for regulatory alignment in commercial and consumer electronic products.
