LOW-OHMIC THICK FILM CHIP FIXED RESISTOR
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.
