Precision Resistors

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.
