“Unicoil” 5 mm

Tunable RF Inductors

Windings are precision molded into plastic for mechanical and electrical stability
Tuning is done by means of an aluminum core
Optional plated brass shield cans with solderable tabs provide integral shielding
165 series offers intermediate L values to the 164 and higher SRF ratings
Samples of all values are available in Coilcraft Designer's Kit M305
Tune with our handy 3-in-1 “TriTuner” tuning wrench
RoHS-compliant. Terminations: Leads – Tin-silver over copper
Shield can tabs – Tin-silver over nickel over brass

Notes

To order fixed inductance parts without cores, eliminate the “A06”, e.g. 164-01L.
Inductance readings taken on Agilent/HP 4286A impedance analyzer with 16092A spring clip fixture.
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.
L min measured with core centered in winding.
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.
