UES1E101MPM

The UES1E101MPM is a bi‑polarized aluminum electrolytic capacitor from Nichicon’s MUSE acoustic UES series, engineered for audio signal circuits. Its 100 µF capacitance at a 25 V rating and compact radial can package make it suitable for incorporation into audio signal paths where bi‑polar operation and small footprint are required.

Designed for audio applications, the part combines low leakage and controlled loss (tan δ) with a temperature range of −40 °C to +85 °C and an endurance rating at elevated temperature for reliable performance in demanding audio equipment.

Key Features

• Bi‑Polarized (Audio‑focused) Bi‑polar construction intended for audio signal circuits and AC audio applications where polarity reversal can occur.
• Capacitance & Voltage 100 µF nominal capacitance with a 25 V rated voltage; capacitance tolerance ±20% (measured at 120 Hz, 20 °C).
• Low Loss & Leakage Tan δ max 0.16 (25 V, measurement at 120 Hz, 20 °C) and specified leakage current of 75 µA (after 1 minute at 20 °C), supporting signal integrity in audio paths.
• Compact Radial Can Package Radial lead, can-style package sized 10 × 16 mm (φD × L) with 5 mm lead spacing for through‑hole board mounting and straightforward placement in compact audio assemblies.
• Temperature & Endurance Operating range −40 °C to +85 °C and endurance of 1000 hours at 85 °C (with polarity inversion every 250 hours), providing predictable lifetime behavior under elevated‑temperature conditions.
• RoHS Compliant & Marking Compliant with RoHS (2011/65/EU, (EU)2015/863). Marking is printed in black on a clear green sleeve for easy identification.

Typical Applications

• Audio signal coupling and decoupling — Used in signal paths to couple stages or block DC while preserving AC audio signals in amplifiers and processing circuits.
• Analog audio circuitry — Suited for use in consumer and professional audio equipment where bi‑polar capacitors are required for AC‑centered signal lines.
• Signal filtering in audio paths — Employed in filter networks and tone control circuits that require stable capacitance and low loss at audio frequencies.

Unique Advantages

• Bipolar design for AC signals: Eliminates polarity constraints in audio signal circuits, allowing safe operation where polarity reversal may occur.
• Compact footprint: 10 × 16 mm radial can and 5 mm lead spacing enable dense board layouts in cramped audio PCBs.
• Measured low loss and controlled leakage: Tan δ (max 0.16 at 25 V) and 75 µA leakage support low‑noise, high‑fidelity audio paths.
• Rated endurance at elevated temperature: 1000 hours at 85 °C (with polarity inversion every 250 hours) provides defined lifetime expectations for designs exposed to higher operating temperatures.
• RoHS compliance: Meets current RoHS requirements for environmentally conscious product designs.
• Clear identification: Black print on a clear green sleeve simplifies part recognition during assembly and servicing.
