USL 0603 Low-Current Fuses

The SCHURTER USL 0603 low-current fuse is designed for safety-critical areas such as ATEX-certified environments. The requirements for miniaturization, precision, and thermal resistance are constantly increasing. This product has been specifically developed to meet these requirements. 

An outstanding feature of the USL 0603 is the extended creepage distance of 1.1 mm (pad-to-pad). This means that it meets the requirements of IEC 60079-11 for 60 V_DC applications in which a minimum creepage distance of 1 mm is required. This makes it one of the few fuses in the 0603 format that can be used without hesitation in ATEX applications such as the oil and gas industry, chemical processing, or mining. 

Thanks to its fast tripping time (tripping at 2.5 times the rated current in under 5 seconds), the USL 0603 offers precise protection for sensitive circuits. At the same time, its low voltage drop ensures minimal energy losses, an advantage that pays off not only in ATEX applications but also in battery-operated designs. 

With an extended operating temperature range of up to +150°C, the fuse is ideally suited for demanding thermal environments, from mobile medical diagnostic devices to industrial sensor applications. 

Ideal areas of application for the USL 0603 are ATEX-certified systems in which potential ignition sources must be avoided through reliable current limitation. The chip fuse is also highly suitable for medical devices where precise tripping times and low power losses are crucial. There are also sensor applications in industry and consumer electronics that are particularly sensitive to overcurrent.
