Mechanical Drawing

Recommended PCB Layout

Schematic

  • 1.

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

  • 2.

    Drive Inductance: Tested at 10kHz, 0.1 VRMS.

  • 3.

    SRF: Values are for reference only.

  • 4.

    Flammability Standard: Meets UL 94V-0.

  • 5.

    ET Product: The maximum ET is based upon a flux density of 2200 Gauss at 25°C.

    ET = EP/2f
    Where as, EP = Primary Voltage (V) f = Frequency (Hz)

  • 6.

    Suitable for bipolar applications only.
