The Schurter 3403.0171.11 is a surface mount fuse from the UMT 250 series, designed for overcurrent protection in compact SMD applications. It is rated for 3.15A continuous current with a slow blow (time-lag) response, suitable for circuits with inrush currents.
Electrical ratings include 250VAC and 250VDC voltage capability, with a high breaking capacity of 200A at 250VAC (IEC) and 35A at 125VDC. The fuse meets IEC 60127-4, UL 248-14, and CSA 22.2 No. 248.14 standards, with approvals from VDE, UL, CQC, KC, and PSE/JET.
The ceramic housing with tin-plated copper alloy terminals ensures durability and reliable soldering. It is MSL 1 compliant and can withstand reflow and wave soldering profiles. Operating temperature range is -55°C to 125°C.
Typical applications include primary protection on SMD PCBs, medical equipment, and battery protection circuits. The fuse is impermeable to potting compounds, making it suitable for intrinsically safe applications per ATEX/IECEx.
