UKT1C222MHD

The UKT1C222MHD is a radial-lead miniature aluminum electrolytic capacitor from Nichicon’s UKT series, optimized for audio equipment and other systems that require compact, high-capacitance filtering. It delivers 2200 µF at 16 V in a φ12.5 × 20 mm can with 5 mm lead spacing, providing a compact solution for smoothing, decoupling, and low-frequency energy storage.

Designed for wide temperature operation (−55°C to 105°C) and endurance under elevated temperature (1000 hours at 105°C), this component combines high ripple current capability with industry-recognized qualification and RoHS compliance for robust, long-term performance in demanding designs.

Key Features

• High capacitance, compact package — 2200 µF (2.2 mF) capacitance in a φ12.5 × 20 mm radial-can package for space-constrained audio and power applications.
• Rated voltage and tolerance — 16 V rated voltage with capacitance tolerance of −20% to +20% for predictable filtering and energy storage.
• Ripple current capability — Low-frequency ripple current 920 mA (120 Hz) and high-frequency ripple current 1.058 A (100 kHz), suitable for demanding audio supply decoupling and power rails.
• Electrical loss and leakage — Dissipation factor (tan δ) of 0.24 (measured at 20°C, 120 Hz) and a measured leakage current of 1056 µA, enabling designers to account for ESR/DF and leakage in precision bias and filter circuits.
• Wide temperature and endurance — Operating range −55°C to 105°C with 1000-hour endurance at 105°C, supporting reliable operation in extended-temperature environments.
• Package and mounting — Radial lead mounting with 5 mm lead spacing (±0.5 mm tolerance), available in bulk or bag packing for flexible assembly choices.
• Qualification and compliance — AEC-Q200 rating and RoHS compliance as listed in product specifications.

Typical Applications

• Audio equipment — DC link and power-supply smoothing in amplifiers, mixers, and active crossovers where high capacitance and low-frequency ripple handling are required.
• Compact power supplies — Bulk energy storage and output filtering in small-form-factor power modules and adapter circuits.
• Industrial and ruggedized electronics — Filtering and decoupling in systems that must operate across −55°C to 105°C and tolerate extended high-temperature use.
• Automotive audio systems — Support for in-vehicle audio power rails where AEC-Q200 qualification is required by the design specification.

Unique Advantages

• High-capacitance density: 2200 µF in a φ12.5 × 20 mm case reduces board area compared with larger cans while retaining bulk energy storage for low-frequency filtering.
• Measured ripple performance: Specified low- and high-frequency ripple current ratings allow designers to size capacitors against expected ripple conditions across the audio band and beyond.
• Wide operating temperature and verified endurance: −55°C to 105°C operation and 1000-hour endurance at 105°C support long-term reliability in elevated-temperature environments.
• AEC-Q200 qualified and RoHS compliant: Enables use in regulated applications and environments that require recognized component qualification and environmental compliance.
• Radial-lead convenience: Standard lead spacing and bulk/bag packing options simplify prototyping and production insertion processes.
