BK30-900-SZ

Ptc Resettable Fuses Overview

The YAGEO BK30-900-SZ is a polymeric positive temperature coefficient (PPTC) resettable fuse from the BK30 series. It features a rectangular design with radial leads for PCB mounting. Key electrical parameters include a maximum voltage rating of 30 V, a holding current of 9 A, and a trip current of 18 A. The device has a maximum rated current of 40 A and a minimum resistance of 5 mohms. It operates within a temperature range of -40°C to +85°C, with a lead spacing of 10.5 mm.

Ptc Resettable Fuses Feature Summary

• Polymeric PPTC technology provides automatic circuit protection that resets after fault clearance.
• Rectangular form factor with radial leads facilitates through-hole PCB integration.
• High current handling capability supports robust overcurrent protection applications.

Ptc Resettable Fuses Applications

• Overcurrent protection in consumer electronics circuits
• Battery pack protection systems
• Industrial control board safeguarding

Ptc Resettable Fuses Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number BK30-900-SZ with official YAGEO documentation. Ensure the received units match the specified 30V rating and 9A holding current. Confirm RoHS compliance status as indicated in the datasheet. Check physical dimensions against the provided ECAD model to ensure proper footprint compatibility before assembly.

Ptc Resettable Fuses Selection Notes

Select this component when a 30V system requires a 9A continuous operating current with an 18A trip threshold. The rectangular package suits applications needing specific spatial constraints on the PCB. Consider the 5 mohms resistance for minimal voltage drop impact. Evaluate thermal management requirements given the 85°C maximum operating temperature limit.

Ptc Resettable Fuses Part Context

This part belongs to the YAGEO BK30 series of resettable fuses. The series offers various current ratings within a 30V envelope. The BK30-900-SZ specifically targets higher current applications compared to lower-rated siblings like the BK30-400-SZ. It utilizes standard radial leaded construction common in industrial and commercial electronic assemblies.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 30V voltage rating, 9A holding current, and 18A trip current specifications. Compatible alternatives should maintain similar rectangular packaging and radial lead configuration for direct PCB replacement. Verify that any substitute part meets the same -40°C to +85°C operating temperature range and RoHS compliance standards.
