Model WVL
Vishay Dale
Inductors
Variable, Subminiature, Shielded
FEATURES
• Classification is Grade 3, Class A.
• Subminiature shielded adjustable inductor.
• High Q values.
• Vertical or horizontal mounting.
• Inductance range is .10µH to 1000µH.
• .300" [7.62mm] diameter by .400" [10.16mm] length.
• Printed board mounting facilitated by .200" [5.08mm] grid
spacing.
• Unit has shield construction to allow maximum density
packaging.
• Accommodates close inductance adjustments in high
density circuits that demand exceptional stability and
high “Q” in the smallest size available.
