Gas Discharge Tubes
High Voltage Series
High Voltage Series
TE Circuit Protection 8mm 2Pole high voltage GDTs
(ceramic gas discharge tubes), are commonly used to
help protect high voltage circuits.
TE Circuit Protection high voltage GDTs offer a high
level of surge protection, low capacitance and a broad
array of break over voltage levels, making them
suitable for applications such as branch circuits,
medical electronics and surge protection on power
lines. TE Circuit Protection GDTs can help equipment
meet the most stringent regulatory standards.
