I have heard to use 0402 component package size for ATF-55143 at 2.4 GHz, but what 0402 would you think they are referring to imperial, or metric? I wanted to look up the size of 0402 package, but this is what they give me: https://www.google.com/search?ei=IV.....0.6.767...0i7i30k1j0i8i7i30k1.0.xKxSjNXZWBY but I am confused about which 0402 would be the best to use for my ATF-55143?
does 0402 and 0603 package refer to imperial or metric? if you search in google "0402 component size," it will direct you to a chart with imperial and metric columns from Wikipedia. I don't understand the difference and its confusing, because all of the numbers look alike and its just happens to be a coincidence?
Metric 0402/Imperial 01005 is 0.4 mm × 0.2 mm or 0.016 in × 0.008 in
Metric 0603/Imperial 0201 is 0.6 mm × 0.3 mm or 0.02 in × 0.01 in
Metric 1005/Imperial 0402 is 1.0 mm × 0.5 mm or 0.04 in × 0.02 in
Metric 1608/Imperial 0603 is 1.6 mm × 0.8 mm or 0.06 in × 0.03 in
