"SLOT TEN" Tunable Inductors

This product will not be available in an RoHS-compliant version. Solder and certain cores contain lead.
  • Versatile inductors operate over a wide frequency range
  • Standard values from less than 1 µH to over 1 mH
  • Precision molded slotted bobbins ensure tight tolerance and high stability
  • Variety of magnetic and electrostatic shielding options
  • Powdered iron tuning cores with hex hole for easy, positive adjustment
  • Tune with our handy 3-in-1 "TriTuner" tuning wrench
  • Samples of 18 shielded and 18 unshielded values are available in Coilcraft Designer's Kit M100

SPECIFICATIONS

Selection Guide

Coilcraft "SLOT TEN" coils come in five different styles. Consult this table for inductance range, relative Q and shielding options of each style. Then use the appropriate chart to pick a specific part number.

1 All readings taken on Agilent/HP 4342-A Q meter.
2 L min is achieved at maximum extension of the core toward PC board. Complete tuning range is reached within the boundaries of the coil form.
3 All specifications are at standard Q meter frequencies. L and Q readings change with frequency.
4 Unshielded parts are coated with lacquer to protect the winding.
5 Shielded parts have a sleeve insert to protect the winding.
6 Operating temperature range −40°C to +85°C. Details
7 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
