# Series Resistor value on RJ45

## Question

Asked by Mon2 on 2020-03-07 in Serial-to-Ethernet & ConfigTool.

Hello. In designing our W7500P based product line, noted that you have errors in the resistor value for the series resistors in the posted schematic.

The Wiz750R (v1.0) shows that R4, R5, R7, R8 = 33R yet the v1.1 & v1.2 PDF documents shows them to be 3.3R.

Assuming that the correct value should be 33R but please confirm.
