RF Ceramic Chip Inductors Johanson Technology RF Ceramic Chip Inductors are high-frequency multilayer inductors that have a monolithic body made of low loss ceramic and high conductivity metal electrodes that result in optimal high-frequency performance. The compact RF Ceramic Chip Inductors from Johanson are constructed with lead-free tin-plated nickel barrier terminations, and the tape-and-reel packaging is ideal for small-size/high-volume wireless applications. These inductors are available in case sizes 0201, 0402, and 0603 with an inductance range from 0.6nH to 220nH.
