Schematic

-
1.
Operating Temp. Range: The combination of ambient temperature and temperature rise.
-
2.
Secondary Inductance: Tested at 10kHz, 0.1 VRMS.
-
3.
Primary DCR (8-7): 4.7 mΩ (Ref)
-
4.
Current Rating: Peak current (50% duty cycle) through primary (8-7) to cause 40°C temperature rise at 25°C ambient.
-
5.
SRF: Values are for reference only.
-
6.
Flammability Standard: Meets UL 94V-0.
-
7.
Terminating Resistor (RB): To calculate the value use the formula, RB = E0TR/Ip
-
8.
ET Product: The maximum ET is based upon a flux density of 3700 Gauss at 25°C. Suitable for bipolar applications only.
ET = EO/2f
EO = IPRB/TRWhere as,
EO = Output voltage (V)
RB = Term. Resistor (Ω)
IP = Primary Current (A)
TR = Turns Ratio
f = Frequency (Hz) -
