Inductors
Variable, Subminiature, Shielded
FEATURES
Subminiature shielded adjustable inductor.
High Q values.
Vertical or horizontal mounting.
Unitized epoxy-molded construction.
Inductance range is .10
H to 100,000H.
.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.
