TIDA-010237: Questions about the TIDA-010237

Part Number: TIDA-010237

Hi

I am inquiring about some questions while reviewing TIDA-010237.

1.The core of TIDA-010237 is Hitachi product and I would like to know the information about the number of turns or turn ratio, and resistance calculation.

2. In the figure below, four lines emerge from the flux gate.
Is it a structure where the two lines at the top and the two lines at the bottom are connected or separated?

Thanks
