FEATURES

  • Rugged metal oxide film
  • High power dissipation in small size (1 W/0207 size to 4 W/0922 size)
  • High temperature coating (up to 200 °C), non-flammable
  • Lead (Pb)-free solder contacts
  • Pure tin plating provides compatibility with lead (Pb)-free and lead containing soldering processes
  • Compliant to RoHS directive 2002/95/EC Notes  Coating: Green  Marking: WK2 and WR4 have color code band marking. TCR band will be given to only WK2, 100 ppm, 5 %. WR5 and WK8 are printed marked. Notes (1) Rated Voltage (2) For values < 10R the upper limiting temperature is 155 °C. The power rating is correspondingly lower and can be calculated by Rth.
