† _{CSR refers to the total series resistance, including the ESR of the capacitor, any series resistance added externally, and PWB trace resistance}
to Co.
‡ _{Pulse-testing techniques are used to maintain virtual junction temperature as close as possible to ambient temperature; thermal effects must}
be taken into account separately.
