Hi brijesh, Welcome to EasyEDA. Are you looking for a simple schematic symbol or a component that you can use in a spice simulation? You can try searching the libraries using the library search tool. Just open a schematic, schematic or spice symbol, PCB or PCB footprint canvas and type: >**SHIFT+F** and try searching for terms like: >*rf_transformer* >*transformer* >*rf* A quick look suggests there may be something suitable or that you can clone, edit and then save to you My Parts library. However, this will probably only find a simple schematic symbol and/or PCB footprint. If you need a *simulation model* then you can try using the transformers or simply a pair of inductors (coupled by the K factor) in the EasyEDA Libs. This Project has several examples: ><https://easyeda.com/project_view_Transformers-and-coupled-inductors_LWewOI0ic.htm> If you need more exact modelling that takes into account the characteristics of the core material then you need to (a) specify more about the Fair-Rite beads and (b) be using the ngspice Inductive Coupling and Magnetic Core XSPICE models: ><http://ngspice.sourceforge.net/docs/ngspice-manual.pdf#subsection.12.2.18> ><http://ngspice.sourceforge.net/docs/ngspice-manual.pdf#subsection.12.2.19> This level of modelling can be done in EasyEDA but is quite an advanced topic so post back if you need help. :)
