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
•Compliant to RoHS directive 2002/95/EC
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.
Note
• General tolerance: ± 0.2 mm
