Each device contains four sets of inductive components, one for each twisted pair within the Ethernet cable.
“WE-LAN AQ transformer convinces in an exemplary fashion in terms of crosstalk, insertion loss, return loss, differential and common-mode rejection,” claimed the firm.
This data sheet gives the numbers as:
- crosstalk (1-100MHz) -35dB min
- Insertion loss (500kHz-100MHz) -1.1dB
- Return loss
1-30MHz -18dBmin
30-60MHz -14.4dBmin
50MHz -13.1dBmin
60-80MHz -12dBmin. - Differential to common-mode rejection ratio
1-60MHz -35dBmin (“minimum values remain the same for CMRR”)
60-100MHz -30dBmin - Insulation test voltage (1 minute) 1,500Vrms

Size is 14.6 x 17.53 x 4.5mm and operation is over -40 to +85°C.
As well as industrial EtherCAT and Profinet applications, the firm foresees use in hubs, routers, switches and IP cameras. The transformers are “compliant with most IC’s for Ethernet applications such as Microchip, Texas Instruments, Broadcom, Linear Technology”, said the firm.
There is also a 10/100 Base-T version.
