(MF0207) Metal Film Resistors
Description
PROFESSIONAL TYPE MINIATURE STYLE
INTRODUCTION
The MFO Series are manufactured by high vacuum sputtering deposit metal film on high thermal conductivity and specific gravity ROSENTHAL ceramic or same grade rods.
The resistors are coated with multilayers of blue coloured laquer.
