GDT gas discharge tube
|
Information of GDT The selection tips of GDT 1. The DC spark-over voltage of GDT should be more than 30% standard voltage and “high-end” tolerance, that protect the Max DC, continuous working voltage and circuits. 2.The IPP of GDT should be more than the surge current of transient circuit. |
