The discrete reference layout will work with thickness from 0.8 - 1.6 mm.
We have seen designs down to .6 mm as well, which had no performance issues.&lt;/p&gt;
&lt;p&gt;PCB material is normal FR-4. Different manufacturers have different spec for dielectric on FR-4.
I believe our supplier specs dielectric of 4.6 nominal.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
