The TPSD687M004R0045: The 45 mOhm ESR at 100 kHz typical keeps ripple heating low in switching-regulator output filters — a 1 A ripple current dissipates 45 mW, well within the D-case's thermal budget. The -55 to 125 °C operating range covers military and industrial temperature profiles; the capacitance change over temperature is roughly +15% at 125 °C and -10% at -55 °C relative to the 25 °C value, per the TPS series typical curve. The ±20% tolerance is standard for tantalum electrolytics — the actual capacitance at 25 °C and rated voltage falls between 544 µF and 816 µF. Design the downstream circuit for the minimum value; the ESR is specified at 100 kHz and is not guaranteed at lower frequencies where the capacitive reactance dominates.
D-case 2917 — footprint and board integration
The molded body has no exposed metal on the top or sides — pick-and-place vacuum pickup is on the top surface. Reflow profile per J-STD-020: the component withstands 260 °C peak for 30 seconds, with a 3× reflow cycle limit.
