Description
Aolittel highly reliable SGH8 Series GDTs provide a high degree of surge protection in a small size ideal for board level circuit protection. GDTs function as switches which dissipate a minimum amount of energy and therefore handle currents that far surpass other types of transient voltage protection. Their gas-filled, rugged ceramic metal construction make them well suited to adverse environments. The SGH8 series comes in a variety of forms including surface mount, core, straight and shaped leads, to serve a variety of mounting methods. The SGH8 Series (75V-110V) is ideal for protection of test and communication equipment and other devices in which low voltage limits and extremely low arc voltages are required. The SGH8 Series (145V-1000V) is ideal for protecting equipment where higher voltage limits and holdover voltages are necessary.
