† CSR (compensation series resistance) refers to the total series resistance, including the equivalent series resistance (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.
