The Schurter 3404.2413.22 is a 500mA board mount fuse from the UMZ 250 series, designed for primary protection on SMD PCBs. It features a time-lag T (slow blow) characteristic, making it suitable for circuits with high inrush currents. The fuse is housed in a ceramic body with gold-plated copper alloy terminals, offering excellent corrosion resistance and reliable soldering. It operates over an ambient temperature range of -40°C to 85°C and has a storage temperature range of 0°C to 60°C with a maximum humidity of 70% r.h. The breaking capacity is 200A at 250VAC (IEC), and the unit is approved by cURus and VDE.
The package is a 2-SMD square end block with clip, requiring a holder for surface mount installation. The moisture sensitivity level is MSL 1 (unlimited), and the product is compliant with RoHS and REACH (unverified). The fuse is suitable for industrial environments and meets the climatic category 40/085/21 per IEC 60068-1. Its compact design maximizes breaking capacity at a minimal footprint.
For design engineers, the slow blow time-lag characteristic allows the fuse to withstand brief overcurrents without nuisance opening, making it ideal for applications with capacitive or inductive loads. The melting I²t value is 0.54 A²s, providing data for coordination studies. The fuse is designed for reflow soldering and has a solderability rating of 245°C/3 sec and resistance to soldering heat of 260°C/10 sec per IEC 60068-2-58.
