Air Core Inductors (Springs)

Air Core Inductor Coilcraft CPS

Coilcraft CPS Air Core Inductors are designed for VHF-UHF RF applications requiring aerospace / military-level performance. Inductance linearity of the coil is not affected by changes in current, so that performance is maintained and unwanted harmonics are minimized. Thirteen series are available to ensure a match for your application.

  • Excellent Q factors – up to 190
  • Current handling as high as 57 Amps!
  • Inductance values from 1.65 to 538 nH
