HiI am on the lookout for a cheap 1:1 pulse transformer. Will be using it to drive a MOSFET based Solid State Switch.I know Larkin has used the DRQ127 I am looking to see if I can find bottom dollar.I probably wont go to LCSC, so would prefer a known brand.Anyone got a recommendation?CheersKlaus

You can use Y caps, then you just need to keep the capacitance below 1nF.
