Mechanical Drawing

Schematic

  • 1.

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

  • 2.

    Secondary Inductance: Tested @ 17.5KHz, 1VRMS, Series. CT03-1000-A is tested @ 1KHz, 1VRMS, Series.

  • 3.

    Current Rating: The primary current rating is for reference only and is limited by the current capacity of the customer-supplied primary conductor.

  • 4.

    SRF: Values are for reference only.

  • 5.

    Flammability Standard: Meets UL 94V-0.

  • 6.

    Terminating Resistor (RB): To calculate the value use the formula,
    RB = EOTR/IP

  • 7.

    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

    Where as,

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

    P/N Designator Suffix:
    C – Center Tapped Secondary
    N – Non-Center Tapped Secondary
