The SA38-302M is a Discharge Tube (GDT/TSS) Axial manufactured by SURGING. It has an overall size of 4.1x10mm and is RoHS compliant. It is a two-terminal component designed to limit current in electronic circuits. It consists of a wire-wound resistor enclosed in a ceramic tube and a spark gap module that produces a low-impedance break-over path when a predetermined voltage is applied. This product is used for surge protection and voltage-limiting in a wide range of circuits and applications.
