What should engineers review before using XG1?

Verify the temperature profile, 3 A current rating, AC 250 V or DC 60 V voltage rating, mounting location, lead handling, and soldering limits. The fuse must not be mechanically stressed or overheated during assembly.

What are the key specifications of XG1?

The rated action temperature is 102 °C, measured fusing temperature is 98 ± 3 °C, holding temperature is 79 °C, maximum limit temperature is 200 °C, and rated current is 3 A.

What is the pinout of XG1?

Use the XG1 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about XG1 pinout to locate pins, power rails, and interface signals before layout.
