RF Magnetics Coilcraft RF Magnetics are a broad range of high-performance, surface-mount RF Magnetic components. These RF Magnetics include high-Q/tight-tolerance ceramic-core and high-inductance ferrite-core chip inductors as small as 0201 (0603) size, ultra-high Q, high current, non-magnetic air core inductors, bias/broadband inductors and chokes, broadband RF transformers, and RFID transponder coils. Coilcraft also offers fixed and tunable through-hole inductors. The components range in inductance from 500pH to 14.8mH with maximum DC currents from 30mA to 13.4A.
