Ptc Resettable Fuses Procurement Notes

Verify the exact part number against official Littelfuse documentation, as RUE090 may be an alias or variant of RUEF090. Confirm RoHS compliance status and specific package dimensions prior to procurement. Ensure the selected component matches the required hold and trip current specifications for the target application circuit design.

Ptc Resettable Fuses Selection Notes

Select this component when a 30 VDC rating and 0.9 A hold current are required for radial leaded applications. Consider the 100 A maximum fault current capability for circuits requiring robust short-circuit protection. Evaluate the 220 mΩ resistance impact on low-voltage signal lines before integration into sensitive designs.

Ptc Resettable Fuses Part Context

The RUE090 belongs to the RUEF series of PolySwitch resettable fuses from Littelfuse. This series represents a comprehensive set of radial-leaded PPTC products balancing voltage ratings up to 30V and hold currents up to 9A. These devices are engineered for reliable protection in various electronic assemblies.
