メモ

Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc.
Volt-time product is for the secondary, between pin 4 and 5.
For specific questions regarding frequency range, please contact us at [email protected].
Primary current of 28 A causes less than 40°C temperature rise from 25°C ambient. Higher current causes a greater temperature rise.
Terminating resistance (R_T) value is based on 1 Volt output with 28 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
R_T (Ohms) = V_out × N_sec / I_in.
3000 Vrms, one minute isolation (hipot) winding to winding.
