The new USL 0603 low-current chip fuse from SCHURTER combines an extended creepage distince of 1.1m, a fast tripping time, and an extended operating temperature range up to 150 °C – meeting the highest requirements in ATEX-certified systems, medical technology, and industrial sensor applications. Due to its low voltage drop, it is also ideally suited for energy-efficient, battery-operated designs.
A key feature of the USL 0603 is its extended creepage distance of 1.1mm (pad-to-pad). This meets the requirements of IEC 60079-11 for 60 VDC applications, where a minimum creepage distance of 1 mm is required. This makes it one of the few fuses in the 0603 format that can be confidently used in ATEX-certified environments – such as the oil and gas industry, chemical processing and mining.
With its fast tripping characteristic (opening at 2.5 times the rated current in under 5 seconds), the USL 0603 offers reliable protection for sensitive circuits. Its low voltage drop ensures minimal power loss, making it especially suitable for battery-operated devices.
Engineered for an extended operating temperature range up to 150 °C, this fuse is well suited for demanding thermal environments – from mobile medical diagnostic equipment to industrial sensor applications.
The USL 0603 from SCHURTER is a suitable choice for ATEX-certified systems, where reliable current limitation is essential to prevent potential ignition sources. It is also a good fit for medical devices requiring precise trip behavior and low power dissipation, as well as industrial and consumer electronics sensor applications that are particularly sensitive to overcurrent.
