Notes
  1. To order fixed inductance parts without cores, eliminate the “A06”, e.g. 164-01L.
  2. Inductance readings taken on Agilent/HP 4286A impedance analyzer with 16092A spring clip fixture.
  3. Q measured on Agilent/HP 4286A with 16092A fixture, direct connected to Agilent/HP 4342A Q-meter and Meguro MQ-171 Q-meter with 0.5" bus bars.
  4. L min measured with core centered in winding.
  5. L max measured with core halfway out top of form.

Termination:

  • Leads: RoHS compliant tin-silver over copper. Other terminations available at additional cost.
  • Shield can tabs: Tin-silver over nickel over brass

Soldering/Washing

Moisture Sensitivity Level (MSL):
1 (unlimited floor life at <30°C / 85% relative humidity)
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.
