Looking at the A suffix 2222, it appears they are graded units having a higher breakdown voltage across the elements. It should work anywhere a 2222 without suffix is specified.
The PN 2222 should work in PN 2222A circuits that do not exceed its element voltage ratings, which if you are building to a 12 volt or less supply source, would be any application. -Stuart K5KVH _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
