Product details

4.7 µF at 35 V — bulk decoupling in a 2917 footprint

The TAJD475K035H is a molded tantalum capacitor from the TAJ series, rated 4.7 µF at 35 V with ±10% tolerance. The 1.5 Ohm ESR sets the ripple current handling and the self-heating under AC load — for a 100 kHz switching regulator output, that ESR limits the ripple current to roughly 1.5 A RMS before the part exceeds its thermal rise. The 2917 (7343 Metric) case fits a standard 7.30 mm × 4.30 mm footprint, common on power input stages and DC-DC output filters.

This capacitor can sit on an avionics power rail cycling between cold-soak and engine-bay heat, or on a downhole instrument board that sees 125°C ambient. The molded case and tantalum construction handle the thermal expansion without cracking the dielectric.

Frequently asked questions

Is TAJD475K035H equivalent to TAJD475K035M?

The suffix H vs M indicates the packaging or reel variant — the core electrical ratings (4.7 µF, 35 V, ±10%, 1.5 Ohm ESR) and the 2917 case are identical. The H suffix is the tape-and-reel option; the M variant may be bulk or a different reel quantity. Both are functionally interchangeable on the same BOM position.

Is TAJD475K035H polarized?

Yes — as a tantalum capacitor, it is polarized. The anode (positive) is marked on the case; reverse voltage will damage the dielectric. Confirm orientation against the PCB silkscreen before reflow.
