Category
The Littelfuse 0154004.DRT is a 4A/125V SMD fuse with 50A interrupt capability designed for low-voltage circuit protection. It features a compact 9.7x5mm package with built-in holder for simplified assembly, offering RoHS compliance and reliable overcurrent protection in consumer electronics, automotive, and industrial applications. Its thermal management requires careful PCB layout to avoid hotspots, and while cost-effective for volume production, it's limited to ≤125V systems and not recommended for high-frequency environments.
