Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix '-A' aligns with your supply chain requirements, as datasheets may primarily reference the base '2016L300/16MR' designation. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation before finalizing procurement orders to ensure regulatory adherence.

Ptc Resettable Fuses Selection Notes

Select this component when a 3.0 A hold current is necessary for continuous operation. Ensure the application voltage does not exceed the 16 VDC rating. Consider the thermal environment, as higher ambient temperatures may reduce the effective hold current capability below the nominal 3.0 A specification.

Ptc Resettable Fuses Part Context

This part belongs to the 2016L series of PolySwitch resettable fuses from Littelfuse. The series offers various current ratings within the same 2016 surface mount footprint, allowing designers to scale protection levels while maintaining consistent board space utilization across different product variants.

Ptc Resettable Fuses Replacement Considerations

The 2016L300/16MR serves as the primary equivalent part number. Verify if the '-A' suffix denotes a specific packaging or compliance variation distinct from the standard reel configuration.
