Deciding the width of Trace

[arm_learner]

trace width required for 200ma

2.8V and 1.8V @ 150-200mA
How is the width enough for that application?
Thanks

Do a SERACH for "PCB Track widths" (I started this Post, so look for Dunn).

I think you may find a solution to the question.

If you still have a problem, just come back.

If you do a google search for PCB track widths, you can find a bunch of online calculators that you can use to best decide for yourself.

Here's a good calculator: https://www.desmith.com/NMdS/Electronics/TraceWidth.html

The 150-200mA is low enoguh for ordinary trace width, say 5mil!

 

[btbass]

5mil is a very thin trace width? For easy manufacture we try to keep minimum trace width to 8mil.

Generally, for 1.4 mail thickness trace, 1A use 1mm width trace

IF ur design is needed to pass FCC, u must take care of EMC.
To ur question, 8 mil is good for use.

I would use 8 mil myself also for that much current. Typical width for current technology.
