100 µF at 20 V — the bulk decoupling anchor
The TPSV107K020R0200: The molded case construction gives it a seated height of 3.75 mm, which fits under low-profile board-to-board spacers or heatsinks in a power supply section.
ESR and temperature range — the real selection gate
The 200 mOhm ESR at 100 kHz is the spec that governs ripple current handling. For a buck converter switching at 500 kHz with 1 A ripple, the I²R loss in this cap is about 0.2 W — well within the package's dissipation capability at 85°C ambient, but at 125°C the derating curve cuts the allowable ripple by roughly half. The -55°C to +125°C operating range covers industrial motor drives and automotive under-hood environments where the ambient hits 105°C and the capacitor self-heats another 10–15°C. The manufacturer size code V corresponds to the 2924 footprint — 7.30 mm x 6.10 mm — which is the largest standard molded tantalum case. That size gives the internal anode enough surface area to achieve 100 µF at 20 V without pushing the dielectric stress above 70% of rated voltage, the typical derating guideline for tantalum reliability.
Active production — no shortage-cycle drama
That means it is still in the regular production schedule — no last-time-buy window, no allocation pressure from the factory. For a BOM cost engineer, this part represents zero single-source risk on the lifecycle front; the TPS series has been a standard molded tantalum line for over a decade, and the 100 µF / 20 V / 200 mOhm combination is a common value that multiple distributors carry.
