Hi there
I have been asked to transpose an old schematic into EDA software for PCB manufacture. The circuit is essentially a 1kW 13.56Mhz RF generator.
My challenge, in addition to knowing nothing about this type of circuit (I do not plan to test / power this thing up myself), is finding components that are in active production for use in the circuit. My task is modelling the PCB and no more than that.
The most troubling components are the capacitors 13-16 and 19-25. Newark/Mouser/LCSC/RS-components --- parts not available or out of stock / I have not been able to identify the correct component from their stock lists.
Whilst I am able to find components that match in terms of capacitance and voltage rating, I am certain that this circuit requires larger package size components. The capacitors indicated by arrows with the 3838 packages are likely working hard and cannot be replaced with much smaller general purpose caps...
My request is thus for recommendations for rugged caps that could be dropped in given the application AND a supplier with stock No small ask.
Please do bear in mind that this is way far out of my area of expertise and I appeal for friendly pointers.
