3403.0170.11 Description

Short technical summary and product information.

The Schurter 3403.0170.11 is a surface mount slow blow fuse from the UMT 250 series, designed for overcurrent protection in compact SMD applications. Rated at 2.5A, it operates at 250 VAC and 250 VDC, offering a high breaking capacity of 200 A at 250 VAC (IEC) and 35 A at 250 VDC.

 

The time-lag (slow blow) characteristic allows the fuse to withstand brief inrush currents while providing reliable protection against sustained overloads. The ceramic housing with tin-plated copper terminals ensures durability and excellent solderability.

 

This fuse is approved by multiple agencies including CQC, cURus, KC, PSE/JET, UL, and VDE, making it suitable for international applications. It is recommended for primary protection on SMD PCBs, medical equipment, and battery protection circuits. The package is 2-SMD, Square End Block, with dimensions 10.10mm x 3.00mm x 3.00mm. Operating temperature ranges from -55°C to 125°C, and it is MSL 1 (unlimited).
