Molded tantalum in an 0805 footprint
The TAJR685K006RNJ is a molded tantalum capacitor from the TAJ series, rated 6.8 µF at 6.3 V with ±10% tolerance. The 0805 case (2.05 mm x 1.30 mm footprint) is the smallest standard size for this capacitance-voltage combination, which constrains the available PCB pad area for thermal management during reflow.
The molded construction provides mechanical protection against vibration and humidity compared to uncoated chip capacitors.
