Metal Oxide Series Resistors

Product Name : METAL OXIDE FILM RESISTORS

Description


INTRODUCTION:
series is a group of electric power type highly reliable fixed resistors with special metal oxide film thermochemically burned on the high heat conductive base material. They include those of flame-resisting coating type and nonflammable coating type and they owing to their uniform quality produced through the most modern production and quality control system, are most reliable products able to use easily for various kinds of electronic devices and instruments.

FEATURES:
  • Electrical and mechanical stability and high reliability.
  • Best resistive to heat, humidity and noncombustible.
  • Annual shift is the lowest for the strengthen metal oxide film .
  • Low noise ,with high resistance value which wire wound type can not be produced.
