UCL1A220MCL1GS

The UCL1A220MCL1GS is a surface-mount aluminum electrolytic chip capacitor in Nichicon's UCL series, offering 22 µF capacitance at a 10 V rated voltage. It combines low impedance characteristics and automotive-grade endurance for electronics that require compact power decoupling and filtering under extended temperature and life conditions.

Designed for applications that demand verified performance across a wide temperature range, this part provides measurable low-loss behavior, controlled leakage, and specified ripple current handling for reliable operation in demanding environments.

Key Features

• Electrical Performance — 22 µF capacitance with a 10 V rated voltage and ±20% tolerance; dielectric loss (tan δ) specified at 0.19 (measured at 20°C, 120 Hz) for predictable AC behavior.
• Low Impedance — Specified impedance of 850 mΩ helps reduce voltage ripple in power rails and improves transient response.
• Ripple Current Handling — Low-frequency ripple current rated at 80 mA (120 Hz) and high-frequency ripple current rated at 160 mA (10 kHz) for mixed-frequency power environments.
• Leakage Current — Maximum leakage current of 3 µA (after 2 minutes at rated voltage, 20°C) for stable bias behavior in long-term operation.
• Thermal and Endurance — Operating temperature range from −55°C to +105°C with a rated endurance of 2000 hours at 105°C under rated voltage.
• Package and Mounting — Surface-mount radial can (SMD) package with a compact size of Ø4 × 5.8 mm and embossed carrier taping for automated placement; recommended land size L: 4.3 mm × W: 4.3 mm.
• Qualification — AEC-Q200 rating for designs that require qualification for automotive reliability expectations.

Typical Applications

• Automotive power modules — Use where a 22 µF, 10 V capacitor with AEC-Q200 qualification and 2000 h endurance at 105°C is needed for local decoupling and smoothing of power rails.
• Control electronics — Suitable for control and sensor electronics that require low leakage and controlled tan δ to maintain stable analog and mixed-signal performance across −55°C to +105°C.
• On-board power filtering — Appropriate for DC–DC converter outputs and power distribution nodes that encounter both low- and high-frequency ripple currents up to the specified ratings.

Unique Advantages

• AEC-Q200 qualification: Provides documented qualification for automotive-grade reliability requirements where such certification is specified.
• Compact SMD can package: Ø4 × 5.8 mm radial can delivers a small footprint suitable for space-constrained boards while supporting automated placement with embossed carrier taping.
• Measured low-loss characteristics: Specified tan δ of 0.19 at 10 V (120 Hz, 20°C) supports predictable AC performance and design margining for decoupling applications.
• Controlled leakage: Leakage current limited to 3 µA ensures minimal bias drain and stable operation in power-sensitive circuits.
• Multi-frequency ripple capability: Defined ripple current ratings at both 120 Hz and 10 kHz enable use in assemblies exposed to a mix of low- and high-frequency disturbances.
• Wide operating temperature and endurance: −55°C to +105°C range with 2000 hours endurance at 105°C supports long-term reliability in thermally demanding applications.
