Lightning countermeasures Surge protection element Ceramic arrester (GDT)
Sankosha Co., Ltd.
About This Product
Ceramic arrester is a surge protection device (Gas Discharge tube (GDT)) that utilizes the phenomenon of electric discharge. Since its initial commercialization, it has been widely used as a countermeasure against lightning surges in communication and signal lines, and now we have over 100 products available. If GDT is used alone in the power supply circuit, there is a risk of follow-on current.
*Other model numbers are available.
