I'm interested in working off the reference design for the nrf51822 to create my own board. I have a few questions about the 3 inductors specified on the schematic/BOM:
-
0402 SMD size parts are specified. Are larger SMD parts OK? (Say, 0603 or 1005)
-
What exactly is meant by "high frequency chip inductor"? Does this relate to the resonant frequency of the inductor and, if so, what resonant frequencies would I want to consider?
-
Are there any recommended (or min/max) current rating or current saturation values?
-
I assume that a multilayer ceramic inductor is what I want. If not, what should I use?
-
I assume that the same selection criteria would also govern the selection of inductors for the antenna. If not, what are the differences?
