Inductors, Variable, Subminiature

Variable, Subminiature, Shielded

ELECTRICAL SPECIFICATIONS

Adjustable Inductance Range: Tunable range; ± 5 % for

0.10 µH to 1 µH. ± 10 % for 1.2 µH to 1000 µH

Dielectic Strength: 840 VRMS at sea level

Working Voltage: 300 VDC

Maximum Current: Based on temperature rise not to

exceed 15 °C at + 90 °C ambient

Incremental Current: The DC current required to cause a

five percent reduction in the nominal inductance value

Operating Temperature: - 55 °C to + 105 °C

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" [5.08mm] 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
