UES1V220MPM

The UES1V220MPM is a bi‑polarized aluminum electrolytic capacitor from Nichicon’s MUSE acoustic series, engineered for audio signal circuitry. It delivers a compact, radial‑lead can package optimized for AC‑coupling and signal path applications in audio equipment.

Key value comes from its audio‑focused design (MUSE series), bipolar construction for symmetry in signal paths, and verified electrical and reliability characteristics suitable for embedded audio designs operating between –40°C and +85°C.

Key Features

• Bi‑Polarized, Audio‑Focused Design Part of Nichicon’s MUSE acoustic series and suited for audio signal circuits, enabling symmetrical AC performance without polarity constraints.
• Electrical Specification 22 µF capacitance at a 35 V rated voltage with tolerance of ±20% and a tan δ max of 0.14 (measurement at 120 Hz, 20°C) for predictable AC behavior.
• Low Leakage Characteristic Leakage current defined as not more than 0.03CV (µA) after one minute’s application of rated voltage at 20°C, allowing controlled DC offset in audio paths.
• Compact Radial Can Package Radial lead mounting with 3.5 mm lead spacing in a can-style package sized L: 1.15 cm × D: 0.8 cm for easy through‑hole placement in compact PCBs.
• Wide Operating Range & Endurance Rated for –40°C to +85°C operation and specified endurance of 1000 hours at 85°C (with polarity inversion every 250 hours), meeting stability requirements for many audio applications.
• Environmental Compliance RoHS compliant per the directive references provided, supporting regulated manufacturing requirements.

Typical Applications

• Audio signal coupling/decoupling: Used for AC coupling and DC blocking in signal chains where bipolar behavior preserves waveform symmetry.
• Preamp and headphone outputs: Suitable for analog stages in preamplifiers and headphone amplifiers that require compact, stable capacitors in the signal path.
• Mixing consoles and audio processors: Employed in analog circuitry of mixers and processors for reliable audio performance across the specified temperature range.

Unique Advantages

• Audio‑centric engineering: As part of the Nichicon MUSE acoustic series, the component is specifically suited to audio signal circuits, supporting design choices focused on sound fidelity.
• Bipolar construction simplifies AC designs: Eliminates the need for split‑bias arrangements in many AC‑coupled audio circuits, reducing component count and layout complexity.
• Predictable AC loss: Specified tan δ (0.14 at 35 V, 120 Hz, 20°C) gives designers a measurable parameter for estimating dissipation in analog signal paths.
• Controlled leakage behavior: Leakage current limited by the 0.03CV formula provides a clear basis for DC offset calculations in precision audio stages.
• Compact, through‑hole form factor: Radial can package with 3.5 mm lead spacing and small footprint (L: 1.15 cm × D: 0.8 cm) eases integration into dense boards and legacy designs.
• Reliability data provided: Endurance and shelf‑life conditions (1000 hours at 85°C, with specified recovery criteria) enable designers to plan for long‑term performance.
