SMD1812B200TF/30

Ptc Resettable Fuses Overview

The YAGEO SMD1812B200TF/30 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for circuit protection. It features a holding current of 2.0 A and a trip current of 4.0 A, operating at a maximum voltage of 30 VDC. The component has a low initial resistance of 5 Ohms and can withstand a maximum fault current of 40 A. It operates within a temperature range of -40°C to +85°C and dissipates up to 800 mW. The device is housed in an 1812 (4532 metric) package with dimensions of 4.37 mm length, 3.07 mm width, and 1.05 mm height.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection by increasing resistance significantly upon overheating due to overcurrent conditions
• Self-resetting functionality restores normal operation after the fault condition is removed and the device cools down
• Designed for surface mount technology integration into printed circuit boards

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection circuits in automotive electronics systems
• Battery pack safeguarding in consumer electronics
• Interface port protection for communication equipment

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix /30 aligns with the required reel packaging configuration for your assembly line. Confirm the voltage rating matches the system's maximum operating voltage to ensure adequate safety margins. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the thermal environment allows for proper heat dissipation during normal operation.

Ptc Resettable Fuses Selection Notes

Select this component when a 2.0 A holding current is required for 30 VDC applications. The 1812 package size offers a balance between current handling capability and board space efficiency. Consider the 800 mW power dissipation limit when designing thermal management strategies. The fast trip time ensures rapid response to short circuit events.

Ptc Resettable Fuses Part Context

This part belongs to YAGEO's SMD series of PTC resettable fuses. It complements other variants like the SMD1812B020TF which offers lower current ratings. The product line focuses on providing reliable protection solutions for modern electronic assemblies requiring compact, self-resetting overcurrent protection mechanisms.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include the SMD1812B200TFT variant from the same manufacturer family. Other manufacturers may offer equivalent 2A 30V PTC fuses in 1812 packages, but electrical characteristics must be verified against the original datasheet specifications.
