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  0.8 - 624 No No Higher Iron Hi Low
2  0.8 - 927 No No | Ferrite Hi Low
3  0.7 - 450 Yes No | Iron Low Med
4  0.8 - 624 Yes Iron | Iron Med High
5  0.9 - 1143 Yes Ferrite Lower Ferrite Med High
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.
