BOM rule hits · not reviewed — A hit means a BOM line matched this category's rules (ruleset 1.0.1+12960cbec977). It is a lead to read, not a located or reviewed circuit; several lines in one category are not several circuits.
Selection parameter template (suggestion)
What one usually states when choosing a circuit of this kind — not the parameters of any design or module listed here, and never a filter.
