“Slot Seven” 7 mm Tunable Inductors
This product will not be available in an RoHS-compliant
version. Core contains lead.
These versatile Coilcraft variable inductors operate over a
wide range of frequencies.Standard inductance values are
available from less than 100 nH to over 250 µH. Custom
values may also be available.
Coilcraft “Slot Seven” RF coils come in an international
7 mm package. Their precision-molded slotted bobbins
ensure tight tolerances and high stability.
All parts come with a metal can that provides electrostatic
shielding. The ferrite sleeve on the 7M3 series provides
higher inductances and additional magnetic shielding.“Slot
Seven” coils are tuned by means of slotted ferrite tuning
cores for easy, positive adjustment. Use the Coilcraft Slot
Tuner for a precise fit to the tuning slug.
