FEATURES
Classification is Grade 3, Class A.
Subminiature shielded adjustable inductor.
High Q values.
Vertical or horizontal mounting.
Inductance range is 0.10
H to 1000H.
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.
