Clay, I'm not sure what the "leadless" package looks like, so I'll check it out.
The only older leadless packages I can't deal with are BGA and the leadless ceramic chip carrier. Would you send me a complete P/N to be sure I'm looking at the right thing? This would still be a very useful accessory, even if the reverse isolation results were down to 60dB.
