Low-Resistance Ferrite Chip Inductors Coilcraft Low-Resistance Ferrite Chip Inductors range in inductance from 15nH to 1mH and offer high current handling. The inductors are developed for ground-to-ground isolation, use in cellular applications like filter elements in bandstop and low-pass filters, and as a one-pole filter or RF choke. These chip inductors are ideal for mobile and infrastructure equipment.
