INTRODUCTION
Featuring consistency and stably-controlled, these carbon film resistors with reasonable prices are widely & largely used in the electronic, electrical and information industries.
This resistor is a ceramic bar tightly coated with a carbon film which is composed of carbon separated from organic compound through the treatment of high-temperature vacuum. After the carbon-coated bar is connected with proper joint and engraved with grooves, its surface is finished with epoxy resin so that the bar is enclosed with a protective film.
FEATURES
  • Industry's lower cost and deliver from stock.
  • Exceptional long-term stability.
  • Exceeds carbon comp MIL-R-11 performance.
  • Standard tolerance: +-2%, +-5%
  • Variety of packing-bilk, strip pack, 26mm and 52mm tape and reel, cut and formed or radial Pana.
