SMD0603B004TF

Ptc Resettable Fuses Overview

The YAGEO SMD0603B004TF is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for circuit protection. It features a hold current of 0.04 A and a trip current of 0.08 A, operating within a voltage rating of up to 15 VDC. The device utilizes a 0603 (1608 metric) package with dimensions of 1.6 mm in length, 0.8 mm in width, and a maximum height of 0.45 mm. It is engineered to withstand operating temperatures ranging from -40°C to +85°C and can endure peak temperatures up to 125°C during fault conditions.

Ptc Resettable Fuses Feature Summary

• Provides automatic resettable overcurrent protection without requiring manual replacement after tripping.
• Utilizes polymer technology to deliver rapid response times when fault currents exceed the trip threshold.
• Designed for compact surface-mount applications with a low-profile footprint suitable for dense PCB layouts.

Ptc Resettable Fuses Applications

• Portable electronic devices requiring battery line protection
• Data and communication ports for surge suppression
• Automotive electronics modules

Ptc Resettable Fuses Procurement Notes

Verify that the specific order quantity aligns with the manufacturer's standard packaging configurations, such as cut tape or reel quantities, to ensure efficient handling. Confirm that the intended application environment remains within the specified thermal limits to maintain reliable performance. Cross-reference the datasheet for any recent updates regarding material compliance or manufacturing changes before finalizing procurement plans.

Ptc Resettable Fuses Selection Notes

Select this component when the circuit requires protection against overcurrent events at low voltage levels. Ensure the hold current exceeds the normal operating current while the trip current remains below the maximum allowable fault current. Consider the thermal environment and space constraints on the PCB to verify compatibility with the 0603 package dimensions and mounting requirements.

Ptc Resettable Fuses Part Context

This part belongs to YAGEO's SMD series of PPTC resettable fuses, which are widely used for protecting sensitive circuits in consumer and industrial electronics. The series offers various current ratings and package sizes to accommodate different design needs. As a passive protection component, it complements active circuitry by providing a robust defense against short circuits and overload conditions.

Ptc Resettable Fuses Replacement Considerations

Substitute parts must match the 0.04 A hold current, 15 VDC voltage rating, and 0603 package dimensions. Verify that alternative manufacturers offer comparable trip characteristics and thermal endurance. Ensure that any replacement maintains the same safety certifications and material composition if required by the end product specifications.
