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.
