0402DF Series inductors

Developed for use in mobile devices and cellular infrastructure equipment, Coilcraft’s new 0402DF Series chip inductors offer higher inductance values and significantly lower DC resistance than other 0402-sized inductors, making them ideal for RF choke and filtering applications.

0402DF SeriesThe 0402DF Series is offered in 25 inductance values ranging from 20 to 3300 nH, with a 5% tolerance for all values. It offers the lowest DC resistance currently available in a 0402 package. For example, the DCR of the 220 nH value is 0.240 Ohms - 55% lower than the same value in Coilcraft’s 0402AF Series - making it fully optimized for use as a harmonic filter element for NFC applications.

0402DF Series inductors can also be used as a filter element in bandstop and low pass filters, a one-pole filter or RF choke in cellular bands, and for ground-to-ground isolation. They feature a ferrite construction for high current handling and RoHS 6/6-compliant matte tin over nickel over silver-palladium-glass frit terminations.
