APPEARANCE

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.
