0465004.DR Description

Short technical summary and product information.

The Littelfuse 0465004.DR is a 4A, 250VAC slow blow (time lag) fuse from the 465 Series NANO2 family. It is designed for surface mount applications and housed in a 2-SMD, square end block package measuring 12.10 mm x 4.50 mm x 4.50 mm. The fuse offers a breaking capacity of 100A at 250VAC, making it suitable for overcurrent protection in power supplies, lighting systems, white goods, and industrial equipment.

Electrically, the fuse has a nominal cold resistance of 0.0160 Ω (measured at 10% of rated current, 25°C) and a melting I²t of 48.4 A²s (calculated at 8 ms). It operates over a temperature range of -55°C to 125°C. The time lag characteristic allows it to withstand temporary inrush currents without nuisance tripping.

The fuse carries agency approvals including PSE and UMF (per IEC 60127-4), and is RoHS compliant and halogen free. It is designed for reflow soldering with Pb-free assembly profiles. Standard packaging is tape and reel (DigiKey part numbers F3671TR-ND, F3671CT-ND, F3671DKR-ND).
