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.
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.
