Vishay Sfernice
7 mm Diameter Miniature Single-Turn Cermet Trimmer
FEATURES
• Industrial grade
• 0.5 W at 70 °C
• Tests according to CECC 41100 or IEC 60393-1
• Low temperature coefficient (100 ppm/K typical)
• Wide resistance range (10
to 2.2 M)
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.
• Easy to read scale
• 7 mm (0.275") diameter
• Material categorization: for definitions of compliance
