The TPSD337M006P0045: The 45 mOhm ESR is the headline parameter for a low-impedance rail — it determines the ripple current capability and the self-heating under AC load. A lower ESR means less internal temperature rise for the same ripple, which directly affects reliability in a power-supply output filter or a processor decoupling bank. Operating temperature spans -55°C to 125°C, covering the full industrial-automotive range. The capacitance tolerance is ±20%, standard for tantalum electrolytics — derate the nominal value by 20% when calculating the minimum capacitance for a regulator loop or hold-up time budget.
D case 2917 — footprint and board-fit
The D case is the standard large-body tantalum size for this capacitance-voltage combination — the 3.10 mm height clears most low-profile board stacks but check the keep-out zone under a mezzanine or opposite-side component. Surface-mount molded case, supplied on tape and reel. The molded construction gives consistent dimensions for pick-and-place and better moisture resistance than conformal-coated parts, though the MSL rating should be confirmed from the lot-specific label.
