UKA1A222MHD

The UKA1A222MHD is a radial-lead aluminum electrolytic capacitor offering 2200 µF capacitance at a 10 V rating with ±20% tolerance. It combines high capacitance in a compact φ12.5 × 20 mm can with characteristics tuned for high-grade audio equipment and applications that require wide temperature operation.

Designed for reliability, this part delivers low-loss performance (tanδ 0.28 at 20°C/120 Hz), rated ripple capability, and a 2000-hour endurance at 105°C. The component is AEC-Q200 qualified and supplied in bulk or bag packing.

Key Features

• Capacitance & Voltage: 2.2 mF (2200 µF) rated at 10 V with ±20% tolerance, providing bulk energy storage for low-voltage audio circuits.
• Low loss performance: tanδ = 0.28 measured at 20°C and 120 Hz, minimizing dissipation in audio power paths.
• High ripple handling: 810 mA at 120 Hz (low frequency) and 931.5 mA at 10 kHz (high frequency), suitable for smoothing and decoupling under dynamic loads.
• Leakage current: 660 µA specified, enabling predictable bias behavior in designs.
• Temperature and endurance: Operating range –55°C to +105°C with 2000 hours endurance at 105°C, supporting long-term operation in demanding environments.
• Package and mounting: Radial lead (polarized) can, size φ12.5 × 20 mm, lead spacing 5.0 mm ±0.5 mm; available in bulk (no terminal forming) or bag packing.
• AEC-Q200 qualified: Conforms to AEC-Q200 requirements as listed in product specifications.

Typical Applications

• High-grade audio equipment: Bulk energy storage and power smoothing for amplifiers and audio power supplies where low-loss performance is needed.
• Audio power decoupling: Filtering and ripple suppression on low-voltage rails in audio signal chains.
• Temperature-challenged audio systems: Use in audio equipment requiring operation across –55°C to +105°C with extended endurance.

Unique Advantages

• High capacitance in a compact can: 2200 µF in a φ12.5 × 20 mm package minimizes board space while providing substantial bulk capacitance.
• Predictable low-loss behavior: Specified tanδ (0.28 at 20°C/120 Hz) helps maintain audio fidelity by reducing dissipative losses.
• Robust ripple performance: Defined ripple ratings at both low and high frequency (810 mA @120 Hz, 931.5 mA @10 kHz) support dynamic supply demands.
• Wide operating temperature and proven endurance: –55°C to +105°C rating and 2000 h endurance at 105°C yield reliable long-term performance.
• AEC-Q200 qualification: Adds confidence for designs that require industry-recognized component stress qualification.
• Flexible packaging: Bulk or bag packing options accommodate production and prototyping workflows.
