Hello friends. I was interfacing an ethernet controller (ENC28J60) using an AVR ATmega8 MCU. So in the magnetics section of the Ethernet controller datasheet I found that I require a Isolation Transformer. So I brought the 4503 1:1:1 from the local market. But the problem is I am unable to find any support for this transformer on the web. So I request you people to pls provide the link of the datasheet if you people have it. And pls state whether this transformer is suitable for the Ethernet applications or not.

 

Sorry for the very late reply. Some one using RP Type 4503 or RP Type 2503 can use the below data's in the image. We contacted the manufacturer directly for the datasheet.
