Mechanical Drawing

Recommended PCB Layout

Schematic

  • 1.

    Operating Temp. Range: The combination of ambient temperature and temperature rise.

  • 2.

    Secondary Inductance: Tested at 10kHz, 1VRMS.

  • 3.

    Primary DCR (8-7): 0.4 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 = EOTR/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/TR

    Whereas,

    EO = Output voltage (V)   TR = Turns Ratio
    RB = Term. Resistor (Ω)       f = Frequency (Hz)
    IP = Primary Current (A)

  • 9.
