Ptc Resettable Fuses Procurement Notes

Verify component authenticity by checking manufacturer markings and datasheet alignment. Confirm RoHS compliance status as indicated in official documentation. Ensure storage conditions maintain integrity before soldering. Validate lead form and spacing against PCB footprint requirements. Review application notes for derating factors related to ambient temperature and holding current adjustments.

Ptc Resettable Fuses Selection Notes

Select this component when a 100 mA hold current and 60 VDC rating match circuit requirements. Consider the 4.5 Ohm initial resistance impact on signal lines or low-voltage supplies. Evaluate thermal management needs due to 380 mW power dissipation during trip state. Compare physical dimensions against available board space. Assess whether radial leads suit the assembly process compared to surface mount alternatives.

Ptc Resettable Fuses Part Context

The MF-R010 belongs to the Multifuse MF-R series of polymeric positive temperature coefficient resettable fuses manufactured by Bourns. This series provides reliable overcurrent protection solutions for various electronic applications. The component utilizes PTC technology to increase resistance significantly upon overheating caused by excessive current flow.

Ptc Resettable Fuses Replacement Considerations

The MF-R010-005 is a documented variant within the same MF-R series offering identical electrical specifications including 100 mA hold current and 60 VDC rating. Verify package dimensions and lead spacing compatibility when substituting between variants.
