The TAJD687M002SNJ: This 680 µF tantalum at 2.5 V rated voltage is a natural fit for a 1.8 V or 1.2 V digital rail where the capacitor sees less than 50 % derating — common practice for tantalum reliability. The 200 mOhm ESR at 100 kHz keeps ripple voltage under control on a switching regulator output, though it is higher than a ceramic cap of the same value.

Frequently asked questions
What is the footprint of TAJD687M002SNJ?
It uses the standard 2917 (7343 Metric) D-case footprint: 7.30 mm x 4.30 mm with a seated height of 3.10 mm max. This is a common tantalum capacitor size, compatible with many existing PCB layouts.
Is TAJD687M002SNJ RoHS compliant?
The TAJ series is typically RoHS compliant, but the specific compliance status for this order code should be confirmed at RFQ. The evidence does not list a RoHS certification number.
