SMD0603B008TF

Ptc Resettable Fuses Overview

The YAGEO SMD0603B008TF is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for circuit protection. It belongs to the SMD0603 series and utilizes a 0603 (1608 metric) package format. The component features a maximum voltage rating of 15 VDC, a hold current of 80 mA, and a trip current of 200 mA. It exhibits a typical response time of 1 second under trip conditions. This device provides overcurrent protection by increasing resistance significantly when fault currents exceed the trip threshold, automatically resetting once the fault is removed and the device cools.

Ptc Resettable Fuses Feature Summary

• Self-resetting functionality eliminates the need for manual replacement after fault clearance
• Compact surface-mount design facilitates automated assembly in space-constrained applications
• Polymeric construction ensures stable performance across specified operating temperatures

Ptc Resettable Fuses Applications

• Portable electronic devices requiring overcurrent protection
• Laptop and notebook computer peripheral circuits
• Communication equipment interface protection
• Battery pack management systems

Ptc Resettable Fuses Procurement Notes

Verify that the specific order matches the SMD0603B008TF designation to ensure correct 80 mA hold current and 15 VDC rating. Confirm package compatibility with PCB footprints prior to placement. Request manufacturer datasheets to validate thermal derating curves and mechanical specifications against application requirements.

Ptc Resettable Fuses Selection Notes

Select this component when circuit protection requires a low-profile surface-mount solution with rapid reset capabilities. Ensure the operating voltage does not exceed 15 VDC and the normal operating current remains below 80 mA. Consider the 200 mA trip threshold to distinguish between transient surges and actual fault conditions during circuit design.

Ptc Resettable Fuses Part Context

This part is a member of the YAGEO SMD0603 series of PPTC resettable fuses. It shares the same physical footprint and general protective function as other variants in the series but differs in electrical ratings such as hold and trip currents. It serves as a reusable alternative to traditional one-time fusible links in modern electronics manufacturing.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 0603 package, 15 VDC rating, and approximately 80 mA hold current. Verify that alternative manufacturers' components meet the same 200 mA trip current specification to maintain equivalent protection characteristics.
