100 mOhm ESR — the ripple-current ceiling
The TPSD107K010S0100: 100 mOhm ESR is the spec that sets the AC ripple current the capacitor can handle before self-heating pushes the core temperature past the derating curve. For a 10 V rail carrying 500 kHz switching ripple, the I²R loss in the ESR determines the usable ripple current — the 100 mOhm figure is the starting point for the thermal calculation.
The 2917 case is a common footprint — no board layout surprises.
The operating temperature range covers the full military/industrial band. The molded case with the D size code (7.30 mm x 4.30 mm x 3.10 mm max seated height) is a standard 2917 footprint. The ±10% tolerance is the standard production grade — no premium for tighter binning.
