Hi! I need to use a filter component. In the reference schematic, its package is 0402 which is too tiny for me and I need the bigger one, say 0603. The problem is I can't find the same spesification. There is always a difference whether its current rating or DC resistance with the component in reference schematic. Any advice how to choose a filter component? And what is the correlation between current rating and DC resistance? Thank you!

 

This is hard to answer without more details. Can you give us more information on the circuit such as your a schematic or a link to the reference circuit?
