    Notes:
    1. Capacitance measured at 1 MHz for all 3H-Series parts is ≤ 3.0 pF
    2. Failsafe device available as model J1F5. A model with the failsafe on bottom, not shown, is also available. Please contact us for more details.
    3. Insulation Resistance for all 3H-Series parts is ≥ 10,000 MΩ measured at:
            DC 50V for the 3H-90 and 3H-150
            DC 100V for the 3H-230, 3H-250, 3H-350, 3H-420 and 3H-500
    4. DC Holdover Voltage measured in accordance with the ITU-T K.12 or the IEEE C62.31-1987 Test Circuit
