AEC-Q200 molded tantalum for automotive and harsh environments
This qualification means the part has passed temperature cycling, moisture resistance, and mechanical shock tests relevant for under-hood, chassis, and infotainment domains. Rated 2.2 µF at 16 V with ±10% tolerance, it fits common 3.3 V and 5 V rail decoupling or filtering roles where a small-case-size tantalum is specified. The 1206 (3216 Metric) footprint and 1.80 mm seated height keep the board-space budget tight. The 2000-hour endurance at 125°C is the reliability ceiling for continuous high-temperature exposure — engine-bay electronics or LED driver circuits that see 105°C ambient still have margin before the capacitor's wear-out accelerates.
Equivalent series resistance is 6.5 Ohm typical at 100 kHz. For a 2.2 µF capacitor on a 500 kHz buck converter output, this ESR contributes roughly 13 mV of ripple voltage at 200 mA ripple current — acceptable for most logic rails but worth checking against the load's ripple sensitivity. A cold-crank environment at -40°C or a hot engine bay at 110°C stays within the rated window without derating the voltage.
Store the reels in a dry environment per the manufacturer's moisture sensitivity level — tantalum molded caps are generally MSL 1, but verify the reel label for bake requirements if the seal is broken.
