Tunable Low Profile
RF Inductors 148 Series

New RoHS part numbers are shown. Lead was removed from terminations. The last character is now L to indicate RoHS compliance. (View old data sheet.)

  • 0.300" / 7,6 height is ideal for low profile applications
  • Windings are precision molded into plastic for mechanical and electrical stability
  • Threaded Carbonyl J core with a slotted socket
  • Extremely economical, even in small quantities
  • RoHS-compliant. Tin-silver over copper terminations.
  • Samples of all values are available in Coilcraft Designer's Kit M304
  • Tune with our handy 3-in-1 "TriTuner" tuning tool

1 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 ½" long soldered along leads and bent at 90° ¼" 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: 0.375/9,5
6 Ambient temperature range: –40°C to +85°C
7 Storage temperature range: Component: –40°C to +85°C
Packaging: –55°C to +80°C
8 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
