No.The first two digits in the part number indicate the application for which the part is intended, and for which it is tested to meet published specs. You can, for example, buy toroids of the same m
wind inductive components (transformers) for 2-4 MHz. Sorry, but I don't consider "inductive" components to include broadband transformers at receiving power levels. Beverage transformers fall into
