hi, I am working on a teensy 3.5 and is there any recommended dc resistance value and frequency for the 600 and 120 ferrite beads on the teensy 3.5?
 
Depends on how much current you expect to draw - but matching the physical size and 100Mhz rating of the teensy ones is a reasonable choice.

Physically larger sizes will provide more noise filtering with the same DC resistance. How important this is depends on the application.
