The AS Series from KYOCERA AVX are Square Air Core Inductors available in Inductance values from 5.5 to 27.3 nH. They have an inductance tolerance from 2 to 10% and are rated for 2.7 to 4.4 A of current. The unique square cross-section of these inductors provides better performance and offers manufacturing advantages over toroidal coils. They are available surface-mount packages that measure 0806, 0807, and 0908 in size and are ideal for RF circuits, broadband I/O filtering, frequency selection, or impedance matching.
