A snubber circuit is added to areas where noise is occurring; in the case of an RC snubber, resistive losses are large, and so the mounting should consider resistor heat generation. Also, while dependent on the frequencies being addressed, if the wiring inductance is large, the effect at higher frequencies is diminished, and so a layout that pays attention to noise will often be more effective.
