WVL
Vishay Dale
Inductors, Variable, Subminiature, Shielded, Radial Leaded
FEATURES
• Classification is grade 3, class A
• Subminiature shielded adjustable inductor
• High Q values
• Vertical or horizontal mounting
• Inductance range is 0.10 µH to 1000 µH
• 0.300" [7.62 mm] diameter by 0.400" [10.16 mm] length
• Printed board mounting facilitated by 0.200" [5.08 mm] grid
spacing
