UUA1V220MCL1GS

The UUA1V220MCL1GS is a chip‑type aluminum electrolytic capacitor from Nichicon’s UUA series, designed for surface mounting on high‑density PC boards. It offers a 22 µF capacitance at 35 V rating in a compact SMD can package and is targeted for automotive and other demanding applications that require AEC‑Q200 qualification and extended high‑temperature life.

Key Features

• Electrical characteristics — 22 µF nominal capacitance with a rated voltage of 35 V and capacitance tolerance of ±20% (measured at 120 Hz, 20°C). The part is polarized.
• High‑temperature endurance — Rated operating temperature range of -55°C to +105°C with a specified lifetime of 3000 hours at +105°C for this package size.
• Ripple handling — Specified ripple current of 44 mA at 120 Hz and 66 mA at 10 kHz, enabling use in fluctuating current environments within its ratings.
• Package and mounting — Chip (radial can) SMD construction optimized for surface mounting on high‑density PCBs; package dimensions L: 5.8 × D: 6.3 mm and recommended land size L: 6.6 × W: 6.6 mm.
• Reliability and qualification — AEC‑Q200 qualified and designed with long life assurance per the UUA series endurance specifications.
• Regulatory compliance — RoHS compliant (2011/65/EU, (EU)2015/863), supporting environmental and regulatory requirements.

Typical Applications

• Automotive electronic modules — AEC‑Q200 qualification and +105°C endurance make this capacitor suitable for automotive control and electronic modules where space is constrained.
• High‑density SMD boards — Chip type and compact footprint are optimized for surface mounting on densely populated PCBs.
• Power conditioning on compact boards — Use where a small, polarized aluminum electrolytic is required for local energy storage and smoothing within the specified ripple and temperature limits.

Unique Advantages

• Long life at elevated temperature: Rated for 3000 hours at +105°C in this package size, supporting extended reliability in high‑temperature environments.
• AEC‑Q200 qualified: Provides a recognized automotive‑grade qualification for designs requiring automotive reliability standards.
• Compact SMD can package: 5.8 × 6.3 mm footprint minimizes board area while supporting surface‑mount assembly on high‑density PCBs.
• Defined ripple performance: Rated ripple currents (44 mA @120 Hz, 66 mA @10 kHz) allow designers to size the part against expected AC stress within the circuit.
• RoHS compliant: Meets current RoHS directives for restricted substances, simplifying regulatory compliance in product designs.
