The TPSE107M016R0125: The 125 mOhm ESR means it handles ripple current without cooking itself — for a 100 kHz switcher dumping 500 mA of ripple, the self-heating stays under 10 °C above ambient.
Molded case, 2917 footprint — field-swappable with the right iron
Molded construction means the tantalum slug is encased in epoxy, not a dipped coating — the case is rigid and the polarity band is clearly marked on top. That is the standard EIA-7343 footprint; you can swap it in the field with a temperature-controlled iron and some flux, no hot-air station needed.
-55 to 125 °C — industrial and under-hood capable
Operating from -55 °C to 125 °C, this cap covers the full industrial temperature range and the under-hood automotive band. The TPS series is a general-purpose line, not a low-ESR or high-reliability variant — the 125 mOhm ESR is moderate, fine for bulk decoupling but not the first choice for a high-ripple output filter where you would reach for a polymer or a low-ESR tantalum.
