Ptc Resettable Fuses Procurement Notes
Verify the specific suffix 'YR' corresponds to the required packaging format, such as cut tape or reel, as indicated by distributor listings. Confirm RoHS 3 compliance status and ensure the 6V rating aligns with the target circuit's maximum operating voltage requirements before finalizing procurement.
Ptc Resettable Fuses Selection Notes
Select this component when a low-voltage, high-current resettable fuse is required for compact PCB layouts. Ensure the application current remains below the 750 mA hold threshold under normal conditions. Verify that the 6V maximum voltage rating exceeds the system's peak voltage to prevent dielectric breakdown during operation.
Ptc Resettable Fuses Part Context
This part belongs to the Littelfuse 1210L series of POLY-FUSE resettable fuses. These components utilize polymer positive temperature coefficient technology to provide reliable overcurrent protection. The series is characterized by its small footprint and ability to automatically reset, making it suitable for space-constrained electronics requiring robust circuit protection.
Ptc Resettable Fuses Replacement Considerations
