BK60-030-DZ

Ptc Resettable Fuses Overview

The BK60-030-DZ is a polymeric positive temperature coefficient (PTC) resettable fuse from the YAGEO BK60 series. Designed for through-hole radial disc mounting, it provides overcurrent protection with a maximum voltage rating of 60V and a holding current of 300mA. The component features a trip current of 600mA and a maximum current rating of 40A. It exhibits a resistance of 80 mOhms and operates within a temperature range of -40°C to +85°C. The lead spacing is specified at 5.1mm.

Ptc Resettable Fuses Feature Summary

• Polymeric PTC technology enables automatic circuit restoration after fault clearance without manual replacement
• Radial disc package design facilitates standard through-hole PCB mounting configurations
• High current capacity supports robust protection against short-circuit conditions

Ptc Resettable Fuses Applications

• Overcurrent protection in consumer electronics circuits
• Protection of portable device power inputs
• Battery pack safeguarding applications

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix DZ aligns with required packaging or marking specifications if critical for assembly processes. Confirm that the 60V rating and 300mA holding current match the target circuit's operational parameters. Ensure the through-hole footprint matches the PCB layout constraints. Cross-reference the datasheet for thermal derating curves to validate performance under expected operating temperatures.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable protection solution is preferred over traditional fuses to reduce maintenance requirements. The 60V rating limits suitability to low-voltage DC applications. Consider the 80mOhms resistance impact on power loss during normal operation. The radial form factor requires adequate board space compared to surface-mount alternatives.

Ptc Resettable Fuses Part Context

This part belongs to the BK60 series of resettable fuses manufactured by YAGEO. The series offers various current ratings within a consistent voltage envelope. The BK60-030-DZ specifically addresses the 300mA holding current requirement within this family. It serves as a reusable alternative to single-use fusible elements in compact electronic assemblies.

Ptc Resettable Fuses Replacement Considerations

Compatible substitutes include other BK60 series variants with matching voltage and current ratings. Verify that any replacement maintains the same radial disc package dimensions and lead spacing to ensure mechanical compatibility.
