“SLOT TEN” 10 mm Tunable Inductors
Document 113-1
Document 113-1 Revised 05/13/11
These versatile Coilcraft variable inductors operate over
a wide range of frequencies. Standard inductance values
are available from less than 1 µH to over 1 mH.
Coilcraft “SLOT TEN” RF coils come in an international
10 mm package. Their precision-molded slotted bobbins
ensure tight tolerances and high stability.
A variety of magnetic and electrostatic shielding options
are offered. “SLOT TEN” coils are tuned by means of
ferrite or powdered iron tuning cores.
Coilcraft Designer’s Kit M100 contains 18 shielded
and 18 unshielded coils (3 each) plus extra cores and
sleeves to create all of the standard values shown. To
order, please contact Coilcraft or purchase on-line at
http://order.coilcraft.com.

Selection Guide
Coilcraft “SLOT TEN” coils come in five different styles. Consult this table for the inductance range, relative Q and
shielding options of each style. Then use the appropriate specification chart to pick a specific part number.
Electrostatic Magnetic Recommended
Style L (µH) shield shield frequency Tuning core Relative Q Relative cost
Style 1 0.8 – 624 No No Higher Iron Hi Low
Style 2 0.8 – 927 No No Ferrite Hi Low
Style 3 0.7 – 450 Yes No Iron Low Med
Style 4 0.8 – 624 Yes Yes (Iron) Iron Med Hi
Style 5 0.9 – 1143 Yes Yes (Ferrite) Lower Ferrite Med Hi
Notes:
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 read-
ings 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.
7. Electrical specifications at 25°C.
