The 500 mOhm ESR tells you the self-heating under ripple current — at 33 µF and 20 V, this part suits bulk decoupling on a 12 V or 5 V rail where the ripple frequency is below a few hundred kHz. The 2917 case (7.30 mm x 4.30 mm footprint, 1.50 mm seated height) is a standard tantalum chip size that fits most reflow profiles for lead-free assembly.
The molded construction keeps the dielectric sealed against moisture ingress, which matters when the board sees condensation or conformal coating.
The evidence does not list a RoHS compliance status for this specific order code. Confirm with the manufacturer or your distributor at order time.
Any 33 µF, 20 V, ±20% tantalum capacitor in a 2917 case with ≤500 mOhm ESR and -55°C to 125°C range is a functional equivalent. The TAJ series is widely second-sourced; check the manufacturer code X for seated height match.
