The TPSD227K010T0150V: 220 µF capacitance at 10 V rated voltage gives you a solid bulk decoupling cap for 5 V and 3.3 V supply rails — the 10 V rating provides derating margin against ripple and transients on a 5 V rail, which is standard practice for tantalum capacitors to avoid surge failures. The 150 mOhm ESR at 100 kHz means this cap can handle the ripple current from a switching regulator without excessive self-heating — a typical 500 kHz buck converter sees ripple current in the 1–2 A range, and this ESR keeps the I²R loss manageable.
Active production – no last-time-buy pressure
Molded case, 2917 footprint – standard land pattern
Molded tantalum in the 2917 (7343 Metric) case — the 7.30 mm x 4.30 mm footprint is a common size for bulk tantalum caps on power input and output stages. The seated height is 3.10 mm max, which fits under most low-profile enclosures. Manufacturer size code D — this is the standard 2917 case height for the TPS series; no unusual clearance issues.
The cap holds its capacitance and ESR across that range, making it suitable for outdoor telecom cabinets, engine-bay electronics, and avionics where the ambient sees extremes.
