1. Primary current of 10 A causes less than 40°C temperature rise @ +2 5°C ambient. Higher current causes a greater temperature rise 

2. Electrical specifications at +25 °C 

3. Part Number Definition: ECSTA1V0805-1xxx-R 

- ECSTA1V0805 = Product code and size 

- 1xxx= Turns ratio sec:pri  1=pri, xxx=sec; 1020=  20:1 

- -R suffix = RoHS compliant
