FEATURES
•
•
•
•
•
•
•
Classification is Grade 3, Class A.
Subminiature shielded adjustable inductor.
High Q values.
Vertical or horizontal mounting.
Inductance range is 0.10µH to 1000µH.
0.300" [7.62mm] diameter by 0.400" [10.16mm] length.
Printed board mounting facilitated by 0.200" [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.
