Chip fuse for ATEX and precision applications

The new USL 0603 low-current chip fuse from SCHURTER combines an extended creepage distance of 1.1mm, a fast tripping characteristic and an extended operating temperature range up to 150degC - meeting the highest requirements in ATEX-certified systems, medical technology, and industrial sensor applications. Thanks to its low voltage drop, it is also ideally suited for energy-efficient, battery-operated designs.

Chip fuse for ATEX and precision applications

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 60VDC applications, where a minimum creepage distance of 1mm is required. This makes it one of the few fuses in the 0603 format that can be confidently used in ATEX-certified environments - including 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.

Designed for an extended operating temperature range up to 150 degC, this fuse is ideally suited for demanding thermal environments - from mobile medical diagnostic equipment to industrial sensor applications.

The USL 0603 is the ideal choice for ATEX-certified systems, where reliable current limitation is essential to prevent potential ignition sources. It is also a perfect fit for medical devices requiring precise trip behaviour and low power dissipation, as well as industrial and consumer electronics sensor applications that are particularly sensitive to overcurrent.
