1 ENP - 1 mil thick Electroless Nickel Plating
3 ENP - 3 mil thick Electroless Nickel Plating

Thanks. blinv,
I means where I can find definition of the code which specific that should apply with 1ENP or 3ENP for higher operating temperature, typically my understanding is 3ENP gives trims pretection more than 1ENP.
Thanks.
