|   EE4.0 SMD Current Sense Transformer Size

EE4.0 SMD Current Sense Transformer L*W*H：4.7*4.3*3.5mm，Flatness<0.15mm

|   EE4.0 SMD Current Sense Transformer Winding

|   EE4.0 SMD Current Sense Transformer Application Circuit and Pins

The terminating resistance R_terminating is calculated based on a 1V output voltage, a primary current of 7A, and 100 turns on the secondary coil. Thus, R_t=14.5Ω

Changing the terminal resistance can increase or decrease the output voltage/current calculation according to the following equation:

R_t (Ohms) = V_out × N_sec / I_pri

|   EE4.0 SMD Current Sense Transformer Application

EE4.0 SMD Current Sense Transformer is widely used in photovoltaic inverters, switching power supplies, detection circuits, and overload protection sockets.
