Molded tantalum bulk cap for harsh-environment decoupling
The TAJD685K050Y is a molded tantalum capacitor from the TAJ series, rated 6.8 µF at 50 V with a 1 Ohm ESR. The 50 V rating provides headroom for 24 V or 28 V rails, and the 1 Ohm ESR keeps ripple voltage in check for bulk decoupling on power inputs or DC-DC output filters.
2917 footprint — board layout and thermal management
The 2917 (7343 Metric) case size measures 7.30 mm x 4.30 mm with a seated height of 3.10 mm. The size code D body provides enough thermal mass to handle ripple current without excessive self-heating, but the 1 Ohm ESR means the capacitor will warm under high-ripple conditions — derate current above 85 °C ambient per the manufacturer's curve.
