Features:  

●Using a radial taping shape with a 5mm lead pitch, suitable for automatic insertion (the height of the component is controlled below 15.5mm). (Except for varieties above 2700V)
●Axial braid can be selected (automatic insertion can also be realized when the glass discharge tube is placed flat).
●The low electrostatic capacitance below 1pF will not hinder the megabit-level high-speed communication signal.
●Using micro-gap method, has excellent surge response effect.
●It has high insulation resistance characteristics above 100MΩ.
