FEATURES
•Wide range of ohmic values
•Low temperature coeffi cient
•Good electrical insulation
•Good mechanical strength
•High power
Specially designed for surface mounting, the MSP series
uses either wirewound or metal fi lm technology.
The molded package ensures mechanical and climatic
protection as well as high dielectric insulation.
The MSP design is compatible with surface mounting
equipment and can withstand wave and refl ow soldering
techniques.
