Air Core Inductors (Springs)
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
