The Littelfuse 5A SMD time delay fuse (part number 01P9283) is designed for surface mount applications and is part of the NANO2 Slo-Blo 449 Series. It features a slow blow characteristic, which allows it to withstand temporary inrush currents without opening, making it suitable for applications where such conditions may occur. The fuse has a maximum voltage rating of 125V AC and 125V DC, with an interrupting rating of 50A at 125V AC. This fuse is RoHS compliant and halogen-free, ensuring compatibility with lead-free soldering processes. It operates effectively within a temperature range of -55¬8C to 125¬8C. The fuse is constructed with a ceramic body and gold-plated caps, providing durability and reliability in various electronic applications. It is suitable for use in devices such as notebook PCs, LCD TVs, power supplies, and telecom systems, among others. Engineers should consider this fuse for projects requiring reliable overcurrent protection in compact designs, particularly where inrush current management is critical.
