Littelfuse 1.85 A Resettable Fuse 72V Radial Lead RXEF185

Littelfuse RXEF185 Resettable Fuse is a high-quality protective component rated for 1.85 A hold current and 72 V voltage, tailored for safeguarding electronic circuits from overcurrent conditions. Featuring radial lead orientation, this fuse offers ease of installation on printed circuit boards and rapid reset capability without replacement.

This PolySwitch™ RXE Series device effectively protects circuits in applications such as printers, satellite receivers, industrial control equipment, computer motherboards, modems, USB hubs, telecommunication devices, and medical instrumentation. Its fast time-to-trip at 12.6 seconds, low resistance, and high voltage rating ensure reliable and precise operation.

The product operates within a temperature range from -40°C to 60°C and dissipates up to 2.1 W power, supporting extended duties in demanding industrial environments. Compliance with global safety and environmental standards including CSA, UL, RoHS, CQC, and TUV guarantees trusted performance and regulatory adherence.

Littelfuse RXEF185 eliminates the need for fuse holders due to its compact size (17.5mm length, 22.4mm height, 3mm width) and maintenance-free auto-reset functionality, allowing for streamlined circuit design and cost efficiency. It withstands repeated fault conditions, automatically returning to low resistance state once power is restored after a trip event.

Automatically resets thousands of times, providing maintenance-free circuit protection. Radial lead orientation suitable for easy PCB mounting. Low hold current of 1.85 A and trip current at 3.7 A ensure precise fault response.

Operates reliably from -40°C to 60°C operating temperature range. Compact dimensions: 17.5mm length, 22.4mm height, and 3mm width for space-saving design. Power dissipation rating of 2.1 W supports stable operation under load.

Complies with CSA, UL, RoHS, CQC, and TUV standards for safety and environmental requirements. Ideal for printers, industrial controls, computer motherboards, telecom devices, and instrumentation. Fast time-to-trip of 12.6 seconds enhances protection against electrical overloads.

This product is essential for industrial, commercial, and telecommunications applications that require reliable, automatic resettable circuit protection with minimal maintenance and compact form factor.
