The Ceramic gas discharge tube can be used in all places that have over-voltages.We should decide the parameter of the GDTs base on the need of the actual circuit and then select the suitable GDTs,
otherwise,we may get the reverse result.The following is the notice when using  the Ceramic gas discharge tubes:

1)Must avoid affecting the normal operation of circuit when using the Ceramic gas discharge tube.
2)Confirm the maximum peak voltage that the circuit can bear,make sure that the GDT's impulse spark-over voltage must be lower than it
3)Based on the possible impulse current energy to select the necessary impulse discharge current volume of  the Ceramic gas discharge tube
4)When the over-voltage disappears, the GDTs must extinguish rapidly to avoid affecting the normal operation of the circuit.
5)If over-voltage lasts significantly longer, GDT's discharge may continue for an extended period and generate significant thermal energy
6)Select suitable volume of  the Ceramic gas discharge tube according to the applied space.
