The Littelfuse 39213150440 is a 3.15A, 250VAC time-lag fuse from the 392 TE5 series. It features a slow blow response time, making it suitable for applications with inrush currents. The fuse is rated for a breaking capacity of 32A (per existing database) and has a nominal cold resistance of 0.017 Ω. It is designed for through-hole mounting in a radial box package with dimensions of 8.50mm x 4.00mm x 8.00mm.
This fuse is approved by CQC, cULus, KC, PSE/JET, SEMKO, and VDE, ensuring compliance with international safety standards. It is halogen free, lead free, and RoHS compliant. The operating temperature range is -40°C to 125°C, allowing use in a wide variety of environments.
The 392 series is known for its reduced PCB space requirements, shock safe casing, and vibration resistance. The 3.15A rating is commonly used in power supplies, lighting ballasts, and industrial control equipment where time-lag characteristics are needed to avoid nuisance openings during startup.
