Marking
All resistors are individually marked with 3 digits. The first two
digits are the significant figures and the third defines the
number of added zeros. Jumpers are marked 000. Types 0201
and 0402 have no marking.
E96 1% components that can not be marked with 4 digits
will be marked with a standard 3 digit code. Details can be
supplied upon request.
Solvent Resistance
The protective epoxy lacquer and marking are resistant to all
normal industrial cleaning fluids suitable for printed circuits.
