| Document 112-1 "Slot Seven" 7 mm Tunable Inductors This product is not RoHS-compliant. Contact Coilcraft for current status or possible alternatives. 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 H. Custom values can also be provided upon request. Coilcraft "Slot Seven" RF coils come in an international 7 mm package. Their precision-molded slotted bobbins ensure tight tolerances and high stability. A variety of shielding options are offered. "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. Coilcraft Designer's Kit M106 contains 39 coils (3 each). To order, please contact Coilcraft or purchase on-line at http://order.coilcraft.com.
