The Schurter 3403.0281.23 is a 5A surface mount fuse from the UMT-H series, designed for primary protection on SMD PCBs. It features a time-lag T characteristic, making it suitable for circuits with pulse-shaped continuous currents. The fuse is rated for 277VAC and 125VDC (with a datasheet note of 250VDC for the series), with a breaking capacity of 1.5kA at rated voltage.
The fuse is housed in a compact ceramic body with nickel/tin-plated copper alloy terminals, measuring 15.40mm x 5.35mm x 5.35mm. It operates over a temperature range of -55°C to 125°C and has a moisture sensitivity level of 1 (unlimited). The component is designed for reflow soldering and is impermeable to potting compounds, enabling use in intrinsically safe applications per ATEx and IECEx requirements.
Typical applications include primary protection on SMD PCBs, sensors, power supplies, intrinsically safe illumination, and battery protection. The fuse holds approvals from CQC, cURus, and VDE.
