UKW1H2R2MDD

The UKW1H2R2MDD is a miniature radial lead aluminum electrolytic capacitor designed specifically for audio and AV equipment. It combines a compact φ5×11 mm can with an audio-focused electrolyte formulation to support sound-quality-conscious designs.

With a rated capacitance of 2.2 µF at 50 V, polarized construction, and a -40°C to 85°C operating range, this part targets compact audio modules and consumer AV applications that require stable performance in a small package.

Key Features

• Capacitance & Voltage — 2.2 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Audio-optimized Electrolyte — Developed electrolyte that the series documentation cites for delivering a harmonious balance of sound quality, making it well suited for AV and audio equipment.
• Low Loss — Tangent of loss angle (tan δ) specified at 0.12 (measured at 20°C, 120 Hz) for the 50 V rating, yielding predictable AC characteristics for audio circuits.
• Ripple Current Capability — Rated low-frequency ripple current of 23 mA at 120 Hz and high-frequency ripple current of 46 mA at 10 kHz for small-signal audio environments.
• Leakage Current — Low leakage current of 4 µA supports low-noise designs.
• Endurance & Temperature — Life expectancy of 2000 hours at 85°C and an operating temperature range from -40°C to 85°C for reliable performance across typical consumer environments.
• Compact Radial Package — Small φ5×11 mm can with 2.0 mm lead spacing (±0.5 mm) in radial lead format for easy through-hole installation; available in bulk (no terminal forming) or bag packing.
• RoHS Compliant — Meets RoHS environmental requirements.

Typical Applications

• AV Equipment — Suited for audio- and video-related electronics where compact, audio-oriented capacitors are required.
• Consumer Audio Devices — Designed for use in compact audio modules and consumer audio electronics that prioritize sound quality in a small footprint.
• Compact Signal Circuits — Applicable where a small, polarized aluminum electrolytic is needed in space-constrained audio circuit designs.

Unique Advantages

• Audio-focused formulation: Electrolyte chemistry developed to realize a harmonious balance of sound quality, supporting audio-centric design goals.
• Small footprint: φ5×11 mm radial can and 2.0 mm lead spacing enable integration into compact PCBs and tight module layouts.
• Predictable AC behavior: Specified tan δ (0.12 at 120 Hz) and defined ripple current ratings provide designers with measurable parameters for audio performance tuning.
• Low leakage: 4 µA leakage current supports low-noise applications and helps maintain signal integrity in audio paths.
• Durability in use: 2000-hour endurance at 85°C and a wide -40°C to 85°C operating range offer design robustness across typical consumer operating conditions.
• Environmentally compliant: RoHS compliance supports regulatory and environmental requirements for modern electronics production.
