FEATURES
•
Approved according CECC 40402-801
(wirewound)
•
Wide range of ohmic values (0.04
Ω
to 1 MΩ)
•
Low temperature coefficient
(± 25 ppm/°C available)
•
Good electrical insulation
•
All welded construction and molded encapsulant
•
High power ratings (up to 2.5 W)
•
Stability class 0.5
•
Pure matte tin termination
Specially designed for surface mounting, the MSP series
uses either wirewound or metal film 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 reflow soldering
techniques.
