Notes
  1. To order fixed inductance parts without cores, eliminate the “J08” or “J12”, e.g. 144-01.
  2. Inductance and Q readings taken on Boonton 260-A Q meter with 16 AWG tinned copper 1/2" long soldered along leads and bent at 90° 1/4" down from stand offs.
    All inductance values greater than 0.1 µH read at recommended Q meter frequency.
    All inductance values below 0.1 µH calculated from readings taken at 50 MHz.
  3. Q min measured at L nom at 40 MHz.
  4. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  5. L min measured with core halfway out top of form.

Termination:

  • Series 142 and 143 leads: Tin-silver over copper
  • Series 144 leads: Matte tin over copper
  • Shield can tabs: Tin-silver over nickel over brass

Soldering/Washing

Resistance to soldering heat:
Wave solder only. Recommended maximum board surface temperature of 168°C (334°F) for no more than three seconds. Pre-heating is recommended to minimize time over the solder nozzle.
Refer to Soldering Coilcraft Components before soldering.
PCB Washing:
Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
