The 0402DF Series are wirewound chip inductors available in twenty five inductance values ranging from 20 nH to 3300 nH. They are developed for use in cellular applications, as a filter element in bandstop and low pass filter and as a one pole filter or RF choke in cellular bands. This series has a SRF ranging from 50 MHz to 2950 MHz. The ferrite construction enables them to handle high current levels and they can be also be used for ground-to-ground isolation.
