    Notes:
    1. DC Breakdown Voltage Ranges are ± 20%
    2. Insulation Resistance measured at:
                DC 50V for the 3YD-90
                DC 100V for the 3YD-230 and 3YD-350
    3. DC Holdover Voltage measured in accordance with the ITU-T K.12 or the IEEE C62.31-1987 Test Circuit
    4. 5 times each polarity
