4.7 µF, 50 V, 300 mOhm ESR — bulk decoupling for 48 V rails
The TPSD475K050Y0300: This combination suits it for bulk decoupling on 48 V telecom or industrial power rails, where the 50 V rating provides headroom above the nominal bus voltage and the ESR keeps ripple heating in check. The D case size (2917 / 7343 metric) and molded construction mean it picks and places on standard reflow profiles without special handling — the molded epoxy body resists cracking from board flex better than conformal-coated chips.
Temperature range and shelf life
Rated for -55°C to +125°C operation, this cap covers the full industrial temperature envelope — no derating needed for outdoor enclosures or engine-bay-adjacent electronics. The ±10% tolerance is the standard precision for tantalum bulk capacitors; tighter bins are not required for most decoupling applications.
Supplied on tape and reel (TR) in the standard 2917 footprint — the reel quantity suits automated pick-and-place lines without reel changeovers for medium-volume builds.
