68 µF bulk cap with a 125 mOhm ESR — what that means on the bench
The TPSW686M006R0125: That ESR figure is the one that governs ripple current handling — at 125 mOhm, the self-heating from ripple stays manageable up to the capacitor's rated current, which is typically around 1.2 A RMS for this case size.
Package and temperature — board-fit and environment
The molded construction gives it better moisture resistance than uncoated chips, which matters if the board sees conformal coating or occasional condensation.
