Notes

To order fixed inductance parts without cores, eliminate the “J12”, e.g. 148-13L.
Inductance readings taken at test frequency on an Agilent/HP 4342A Q meter with 1/2″ long, 16 AWG tinned copper wire soldered along the leads and bent at 90°, 1/4″ from standoffs. Inductance values at 50 MHz calculated from Cp readings. Inductance values at 25 MHz read at standard Q meter frequency (blue line)
Q readings taken at test frequency on an Agilent/HP 4342A Q meter with 1/2″ long, 16 AWG tinned copper wire soldered along the leads and bent at 90°, 1/4″ from standoffs.
L min measured with core halfway out top of form. L max measured with core centered in the windings.

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.
