UES1H2R2MDM

The UES1H2R2MDM is a bi-polarized aluminum electrolytic capacitor from Nichicon’s MUSE acoustic series, engineered for use in audio signal circuits. Its bi-polar construction and audio-focused design make it suitable where symmetrical signal handling and sonic integrity are required.

Packaged as a compact radial-can with 2 mm lead spacing (L: 1.1 × D: 0.5 cm) and a rated voltage of 50 V, this capacitor offers a -40 °C to 85 °C operating range and a specified endurance of 1000 hours at 85 °C, making it appropriate for PCB-mounted audio equipment that requires reliable, long-life passive components. It is RoHS compliant.

Key Features

• Capacitance & Voltage — 2.2 µF nominal capacitance rated for 50 V operation, with tolerance of -20% to +20% for predictable performance in design.
• Bi-Polar Construction — Bi-polarized design from the "nichicon MUSE" acoustic series, suited specifically for audio signal circuits where non-polar operation is required.
• Compact Radial Can Package — Radial lead, can-style package with 2 mm lead spacing and overall dimensions L: 1.1 × D: 0.5 cm, optimized for through-hole PCB mounting in compact audio assemblies.
• Temperature & Endurance — Rated for operation from -40 °C to 85 °C with a guaranteed lifetime of 1000 hours at 85 °C (endurance test includes polarity inversion every 250 hours as specified in the series datasheet).
• Electrical Loss & Leakage Characteristics — Series specifications include a maximum tan δ of 0.12 at 50 V (measured at 120 Hz, 20 °C) and a leakage current limit defined as not more than 0.03CV (µA) after one minute at 20 °C, supporting low-noise audio paths.
• Regulatory Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Signal Circuits — Suited for audio signal circuits where bi-polar behavior and audio-grade component choice are required.
• Audio Equipment — Designed as part of the nichicon MUSE acoustic series for use in consumer and professional audio equipment assemblies.
• Through-Hole PCB Designs — Radial lead can and compact dimensions make it appropriate for through-hole audio boards and modules with space constraints.

Unique Advantages

• Audio-Focused Construction — Bi-polarized MUSE acoustic-series design targets audio signal integrity without requiring polarity-specific installation.
• Compact Footprint — Small can dimensions (L: 1.1 × D: 0.5 cm) and 2 mm lead spacing help conserve board area in dense audio assemblies.
• Defined Endurance Protocol — Endurance specified at 1000 hours at 85 °C with polarity inversion every 250 hours, providing a measurable reliability baseline for design qualification.
• Low Loss and Controlled Leakage — Series-level tan δ and leakage current limits support cleaner signal paths in audio applications.
• RoHS Compliant — Meets current RoHS requirements for lead-free electronics production and regulatory consistency.
