The 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 the company’s 0402AF Series – suiting it 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.
