T7
Vishay Sfernice
Miniature Cermet Trimmers
FEATURES
• Industrial grade
• 0.5 Watt at 85 °C
RoHS
COMPLIANT
• Test according to CECC 41100
• Low temperature coefficient (100 ppm/K typical)
• Wide resistance range (10 Ω to 2.2 MΩ)
• Easy to read scale
The T7 trimmer is only 7 mm (0.275") in diameter and fits
almost anywhere.
A dust sealed plastic case protecting a quality cermet track
guarantees high performance and proven reliability.
Adjustments are made easier by the clear scale readings. T7
is ideally suited to all industrial applications.
