Ditto for SMT resistors with more than say 10V across
them, and that might experience moderate power surges.
My technician's front-loading washing machine control
board (with elegant Analog Devices DSP six-IGBT three-
phase VFD motor-drive controller) failed when an 0805
resistor blew in the offline switching-supply circuit.
My beautiful expensive Casablanca remote-controlled
multi-speed reversible ceiling fan failed when an
SMT resistor failed, similar story.
And etc.
