TSM4
Vishay Sfernice
Surface Mount Miniature Trimmers
Multi-Turn Cermet Sealed
FEATURES
•0.25 Watt at 85 °C
•Professional grade
•Wide ohmic range (10 Ω to 1 MΩ)
•Low contact resistance variation (2 % or 3 Ω)
•Small size for optimum packing density
•Suitable for both manual or automatic operation
The TSM4 trimming potentiometer has been designed for
surface mount applications and offers volumetric efficiency
5 x 5 x 3.7 mm3 with high performance and stability.
The TSM4 design is suitable for both manual or automatic
operation, and can withstand vapor phase and reflow
soldering techniques.
