UKW2A2R2MDD

The UKW2A2R2MDD is a Nichicon UKW-series aluminum electrolytic capacitor in a compact radial-lead can designed for audio and AV equipment. It provides a 2.2 µF capacitance at a 100 V rating, polarized construction, and a small φ5 × 11 mm package with 2.0 mm lead spacing.

Engineered for audio applications, this part combines a low loss tangent (tanδ = 0.08 at 20°C, 120 Hz) with defined ripple current handling and low leakage to support reliable performance in signal and power circuits within consumer and professional audio equipment.

Key Features

• Electrical Rating — 2.2 µF capacitance with a 100 V rated voltage and polarization for circuits that require a compact high-voltage electrolytic solution.
• Low Loss Performance — tanδ (DF) of 0.08 measured at 20°C and 120 Hz for minimized dissipation in audio-frequency circuits.
• Ripple Current Capability — Low-frequency ripple current 30 mA (120 Hz) and high-frequency ripple current 60 mA (10 kHz) to handle typical ripple conditions in audio-related power stages.
• Low Leakage — Specified leakage current of 6.6 µA for stable bias behavior in sensitive circuits.
• Mechanical / Package — Radial-lead, can-style package: φ5 × 11 mm overall size with 2.0 mm lead spacing (±0.5 mm), supplied in bulk/bag packing without terminal forming.
• Temperature and Endurance — Operating range −40°C to +85°C with 2000 hours rated endurance at 85°C.
• RoHS Compliance — Compliant to RoHS requirements as indicated for the UKW series.

Typical Applications

• Audio Equipment — Intended for AV and audio systems where low loss and controlled leakage support signal integrity and sound quality.
• Consumer AV Electronics — Compact radial form factor fits space-constrained designs in receivers, amplifiers, and other AV modules.
• Power and Filtering in Audio Circuits — Used where a small, polarized electrolytic capacitor is required for power rail smoothing and ripple attenuation at audio-relevant frequencies.

Unique Advantages

• Audio-oriented electrolyte formulation — The UKW series was developed to realize a harmonious balance of sound quality, supporting AV and audio applications.
• Compact high-voltage option — 100 V rating in a φ5 × 11 mm can enables higher-voltage circuit designs without large can sizes.
• Measured low dissipation — tanδ = 0.08 at 20°C/120 Hz reduces self-heating and energy loss in the audio band.
• Defined ripple performance — Specified ripple current values at both low and high frequencies help designers account for thermal and ripple stress in application-level designs.
• Long endurance at elevated temperature — 2000 hours at 85°C provides predictable lifetime characteristics for product planning and reliability analysis.
• RoHS-compliant — Conforms to environmental requirements for modern electronics manufacturing.
