www.watchfuleyesolutions.com Gas Discharge Tube (GDT)

W18G-800 is GDT designed for protection of power lines. Low insertion loss is also perfectly suited to broadband equipment applications.
The GDT operates as a symmetrical voltage-dependent switch. Features as very high surge current handling capability, very high insulation resistance and ultra-low capacitance meet almost perfectly all requirements made on a protective element.
