### EML 5u4G-mesh and minimum required copper resistance

Posted:

**Tue Oct 17, 2017 10:01 pm**Hi

I am interested to use a EML 5U4G mesh in my amplifier, but I have a question about the minimum required copper resistance of the transformer winding. I see in the EML web page that the minimum Raa value for the curve 1 to 6 is 170 ohm. This value is different form the data sheet of the other manufacturer. Please if you see for example the Sylvania 5u4G or GE you can find a much less value. So, because in my amplifier I have a Raa of around 80 ohm ( and first capacitor of the filer of 22 uF, and 180 mA dc current to the load) , I ask if I can use the EML 5U4g without risk of damage it. Thank you very much
