High Voltage Series
Littelfuse Circuit Protection 8mm 2Pole high voltage
GDTs (ceramic gas discharge tubes), are commonly
used to help protect high voltage circuits.
Littelfuse 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. Littelfuse Circuit Protection GDTs can help
equipment meet the most stringent regulatory
standards.
