1. INTRODUCTION
To fill the function gap of carbon film resistors, metal oxide film
resistors or wire wound resistors SYNTON-TECH mages metal
film resistors. The resistive element is a high contests of AL203
ceramic rod on which a thin film of Ni/Cr alloy is deposited by
vacuum sputtering system. Then contact caps are pressed onto
the ends of the rod and a helical grove cut through the film to
give the required resistance value. Connecting copper wire are
welded to the end caps. Finally the resistors are coated with
multiple layers of insulation lacquer.
SYNTON-TECH’s
MF series are suitable for all circuit applications especially
tighter tolerance and low temperature coefficient are required.

FEATURES
Meet American military specification
MIL-R-10509F!
Very low current noise!
Major applications are switching power sup-
plies, communications equipment, monitors,
testing meters.
