Bourns 2046 & 2028 GDTs

Bourns 2046 and 2028 Series GDTs are 8mm x 10mm Gas Discharge Tubes. The 3-electrode devices feature a maximum 8/20µs surge current rating of up to 30kA. Both series are RoHS compliant and model 2046 is UL Recognized. Bourns 2046 and 2028 Series GDTs are ideal for telecom applications requiring ITU compliance but are suitable for many other applications. An optional fail-short mechanism is available for thermal runaway protection.
