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












5












$begingroup$


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.

            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.

            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.

              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.

                        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.

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

                                        ASUS Zenbook UX433/UX333 — Configure Touchpad-embedded numpad on Linux

                                        Image
                                        0 1 I have an ASUS Zenbook UX433,on which ASUS decided to innovate by embedding a Numpad inside the touchpad (see picture 1). Toggling between classic touchpad mode and numpad (also turns the touchpad LEDs on) can be done through the golden button in the top-right corner of the touchpad. However, on my Manjaro arch Linux config, this behavior does not work by default and I can only use the touchpad, no numpad. Has anyone been able to configure the numpad to work on Linux, or have any idea how this could be achieved? EDIT1: I have had a look at the official Windows drivers for the UX433FA TouchPad, but was not able to make anything of it. I tried installing them on Linux using tools like NDISWrapper, but they do not detect the TouchPad/Numpad hardware, and my understanding of drivers is too limited.
