    Notes:
    1. Insulation Resistance for all part numbers is ≥ 10,000 MΩ measured at:
            DC 50V for the 3SD4-75, 3SD4-90 and 3SD4-145
            DC 100V for the 3SD4-200 and 3SD4-230
    2. DC Holdover Voltage measured in accordance with the ITU-T K.12 or the IEEE C62.31-1987 Test Circuit
    3. Capacitance measured at 1 MHz for all part numbers is ≤ 1.0 pF
