That is the nominal load it can carry under normal operation."},{"question":"Is STEF4SPUR suitable for hot-swap applications?","answer":"Yes, the electronic fuse function with high-side sensing and controlled turn-on makes it well suited for hot-swap controller roles where you need inrush current limiting and overcurrent protection on a 10V rail. The 5A output covers typical hot-swap loads in industrial and telecom gear."},{"question":"What package does STEF4SPUR come in?","answer":"The STEF4SPUR is supplied in a 10-WFDFN exposed-pad package (3x3 mm) for surface-mount assembly.
