| Document 111 Tunable RF Inductors - 148 Series With an overall height of only 0.300, these tunable coils are ideal for applications where low-profile circuit boards are essential. The windings are precision molded in plastic to guarantee a constant winding pitch and a consistent relationship to the printed circuit board. Tuning is done by means of a threaded Carbonyl J core. Coilcraft Designer's Kit M304 contains three samples each of the values shown plus 20 values from the 132 Series of low-profile, high Q fixed inductors.

To order fixed inductance parts without cores, eliminate the "J12", e.g. 148-13L. 2. Inductance and Q readings taken on Agilent/HP 4342-A Q meter with 16 AWG tinned copper 1/2 long soldered along leads and bent at 90 1/4 down from standoffs. 3. L min measured with core halfway out top of form. L max measured with core centered in the windings. 4. Inductance values at 50 MHz calculated from Cp readings. Inductance values at 25 MHz read at standard Q meter frequency (blue line). 5. Core material: Carbonyl J. Core length: 3/8. 6. Operating temperature range -40C to +85C. 7. Electrical specifications at 25C. 0.275 max 6,99 0.310 typ 7,87 0.300 max 7,62 0.190 typ 4,83 0.250 0.030 typ 6,35 0,76 22 AWG 0.198 0.010 5,03 0,25 0.360 0.010 9,14 0,25 Weight: 0.7 - 1.2 g Terminations: Tin-silver over copper Specifications subject to change without notice.
