BK16-500-SZ

Ptc Resettable Fuses Overview

The BK16-500-SZ is a polymeric PTC resettable fuse manufactured by YAGEO. It features a maximum voltage rating of 16V and a hold current (Ih) of 5A. The device has a trip time of approximately 2 seconds and exhibits a low resistance of 0.014 ohms. Designed for through-hole mounting, it utilizes a radial disc form factor with dimensions of 0.421 inches in length and 0.122 inches in width.

Ptc Resettable Fuses Feature Summary

• Polymeric positive temperature coefficient technology for automatic circuit protection
• Through-hole radial disc construction for reliable PCB integration
• Low on-resistance characteristic to minimize power loss during normal operation

Ptc Resettable Fuses Applications

• Overcurrent protection in consumer electronics
• Protection circuits for portable devices
• Automotive grade electronic assemblies

Ptc Resettable Fuses Procurement Notes

Verify the specific package orientation and lead frame configuration against the manufacturer's mechanical drawing prior to design finalization. Confirm that the thermal environment supports the required trip characteristics. Ensure the selected component matches the exact series designation to guarantee consistent electrical performance across production batches.

Ptc Resettable Fuses Selection Notes

Select this component when a 16V system requires overcurrent protection with a 5A hold current threshold. Consider the 0.014 ohm resistance impact on circuit efficiency. Evaluate the 2-second trip time against the load's surge tolerance requirements. Ensure the physical footprint fits the designated through-hole layout constraints.

Ptc Resettable Fuses Part Context

This part belongs to YAGEO's BK series of polymeric resettable fuses. These components serve as reusable alternatives to traditional one-time fuses. The series provides robust protection against short circuits and excessive current conditions in various electronic applications.

Ptc Resettable Fuses Replacement Considerations

The BK16-600-SZ is a confirmed substitute within the same product family. Verify that the alternative's electrical ratings align with the original design specifications before implementation.
