Isolation transformer

An isolation transformer, applicable to automotive Ethernet, comprising:

• a common mode choke;
• a first capacitor electrically connected to the common mode choke through an end;
• a second capacitor electrically connected to the common mode choke through an end;
• a first resistor electrically connected to another end of the first capacitor through an end;
• a second resistor electrically connected to another end of the second capacitor through an end;
• a third resistor electrically connected to another end of the first resistor and another end of the second resistor through an end, and connected to a reference potential point through another end;
• and
• a third capacitor electrically connected to said another end of the first resistor and said another end of the second resistor through an end, and connected to the reference potential point through another end;
• wherein a power consumption of each of the first resistor and the second resistor is greater than 0.4 watt, and
• wherein a capacitance of the third capacitor is 4.7 nanofarad.
