150 µF bulk cap for 4 V rails — what the ESR tells you
That 80 mOhm ESR is the key number for a bulk decoupling decision: at the switching frequency of a downstream regulator, the impedance of the capacitor is dominated by the ESR, not the capacitance. For a 4 V rail drawing 2 A ripple, the 80 mOhm ESR produces 160 mV of ripple voltage — check that against your load's tolerance before committing the BOM.
Full military temperature range — where it fits
That means it holds its capacitance and ESR through avionics cold-soak, downhole tool heat, and satellite thermal cycling — environments where a commercial 85 °C cap would drift out of spec. The molded case (C code, 2312 footprint) handles the mechanical stress of those cycles without cracking the dielectric.
