  • MF - Metal Film use nickel-chromium or a similar alloy deposited on a ceramic rod by a vacuum process of evaporation or sputtering.
  • The final resistance value is (most commonly) defined by cutting an insulating path through the film along the length of the rod while keeping it in rotation.
  • The technology is capable of supporting accuracy characteristics over a broad resistance range.
  • Types include axial through-hole and metal film fusible for special purpose.
