UES1E220MEM

The UES1E220MEM is a bi-polar aluminum electrolytic capacitor from Nichicon's MUSE acoustic series, specifically designed for audio equipment and audio signal circuits. It provides 220 µF capacitance at a 25 V rating in a compact radial-can package suitable for space-constrained audio designs.

Key electrical characteristics include a capacitance tolerance of ±20% (120 Hz, 20°C), a tangent of loss angle (tanδ) of 0.16 at 120 Hz/20°C, low leakage current after voltage application, and an operating temperature range of −40°C to 85°C with a rated lifespan of 1000 hours at 85°C.

Key Features

• Bi‑polarized audio design Bi-polarized construction tailored for audio signal circuits and audio equipment where AC-coupling and symmetric polarity handling are required.
• Electrical performance 220 µF capacitance at 25 V with ±20% tolerance (120 Hz, 20°C); specified tanδ of 0.16 at 120 Hz/20°C for predictable AC loss behavior in audio paths.
• Leakage and endurance Leakage current specified as 16.5 µA after 1 minute at 20°C; endurance rating of 1000 hours at 85°C (with polarity inversion per datasheet test procedure).
• Temperature range Wide operating range from −40°C to 85°C to support a variety of audio equipment environments.
• Compact radial package Radial lead, can-style package with dimensions L: 11 mm × D: 6.3 mm and lead spacing 2.5 mm ±0.5 mm for through-hole mounting in compact PCB layouts. Supplied in bulk with clear green sleeve marking in black lettering.
• Regulatory compliance RoHS compliant; part of Nichicon’s MUSE acoustic series focused on audio performance.

Typical Applications

• Audio signal circuits — Coupling, decoupling and AC‑coupling applications in consumer and professional audio equipment where bi‑polarized capacitors are required.
• Audio equipment — Use in preamplifiers, signal-processing modules and other audio subcircuits that demand predictable loss and leakage characteristics.
• Compact through‑hole designs — Small radial-can footprint for space-constrained PCB layouts in desktop audio devices and compact electronic equipment.

Unique Advantages

• Bipolar construction for AC handling: Enables symmetric signal coupling and simplifies designs that require polarity-independent operation in audio paths.
• Audio-oriented electrical specification: Defined tanδ (0.16 at 120 Hz/20°C) and controlled leakage current support consistent behavior in signal chains.
• Compact form factor: 6.3 mm diameter and 11 mm length provide a small footprint for through-hole boards without sacrificing capacitance.
• Predictable endurance: Rated for 1000 hours at 85°C under the datasheet test conditions, enabling designers to plan for long-term performance in elevated-temperature environments.
• RoHS compliant: Meets regulatory requirements for lead-free assembly and global environmental directives.
