APPEARANCE
Basic requirement
,
The surface of resistor is covered with Protective Coating which hard to fade, and
the surface of coating should avoid unevenness.
The terminal part is covered equable , the plating is hard to fade, and should avoid
unevenness,flaw, pinhole and discoloration.
With a clear mark , the resistor body is crack-free.
