“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

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 L max measured with core halfway out top of form
4 L min measured with core centered in winding
5 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
6 Irms: Current that causes a 15°C rise from 25°C ambient. Details
7 Core material: Aluminum, 0.187" long
8 Ambient temperature range: −40°C to +85°C
9 Storage temperature range: Component: −40°C to +85°C
Packaging tubes: −40°C to +80°C
10 Electrical specifications at 25°C.
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.
