    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.
