The Yenji GS41-201M is an axial Gas Discharge Tube (GDT) with RoHS compliance. This GDT is a type of surge protective component, typically used in power supplies, medical equipment and AC-DC adaptors. It acts as an over-voltage protector by breaking down in the presence of voltage exceeding a certain amount, thus providing a short-circuit. The GS41-201M features a wide variety of characteristics including a voltage rating of 200V, a maximum operating current of 15mA and an impulse current of 250A. When open-circuited, it has an insulation resistance of >100MOhms. The physical characteristics of the GDT include an insulation standoff of 8.2mm, a total diameter of 11.5mm and a length of 10mm. The GS41-201M is also RoHS compliant, ensuring it follows standards that are in place to protect the environment.
