Type MS Power Film Resistors
Page 2 of 2
Construction:
The Type MS Power
Film Resistor is constructed
with Micronox® resistance films
bonded to a high strength solid
ceramic core. Nickel alloy end caps
and axial leads complete the assembly.
Encapsulation is provided by a high
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
