Film Resistor is constructed
Film Resistor is constructed
with Micronox
with Micronox
bonded to a high strength solid
ceramic core. Nickel alloy end caps
and axial leads complete the assembly.
E n c a p s u l a t i o n i s p r o v i d e d b y a h i g h
temperature silicone conformal coating.
Type MS: Lead material is Nickel Clad Copper
with thin Gold Plate, solderable.
For welding applications, optional pure nickel
leads are available on Models MS126, MS150,
MS151, MS175, MS176, MS210. Contact
