What does bar symbol in parallel with a single inductor indicate?












4












$begingroup$


Some circuits have parallel bars on their inductor symbols such as:



enter image description here



Does that mean the inductor is wound around a magnetic core insread of air? Is that how a differential choke is represented?

          Typically yes. The bar is used to indicate some form of ferrous core.

            I see this convention for ferrites such as in the filter you show, tho I can't seem to find an official source indicating this is an official standard of some kind.

              solid bar indicates - ferrous core (core made of a ferrous metal, such as iron).



              dashed bar indicates - ferrite core.

                yes.. air core colis will have much more less inductance when compared to iron or ferrite core inductors.

              Well, IEEE Std 315 specifies this symbol for an inductor with a "magnetic core":



              inductor with core, symbol from IEEE Std 315



              The standard doesn't show any symbols with a single bar, at least as far as I can see.

                                solid bar indicates - ferrous core (core made of a ferrous metal, such as iron).



                                dashed bar indicates - ferrite core.

                                Well, IEEE Std 315 specifies this symbol for an inductor with a "magnetic core":



                                inductor with core, symbol from IEEE Std 315



                                The standard doesn't show any symbols with a single bar, at least as far as I can see.
