0ZCG0200AF2B

Ptc Resettable Fuses Overview

The 0ZCG0200AF2B is a polymer PTC resettable fuse from the Bel Fuse 0ZCG series, designed for surface mount applications in an 1812 (4532 metric) package. It features a maximum voltage rating of 60V and a hold current (Ih) of 200 mA. The device trips at a current of 400 mA with a typical trip time of 20 ms. Initial resistance is 800 mOhms minimum, while post-trip resistance reaches up to 5 Ohms maximum. It supports a maximum fault current of 40 A and operates within a temperature range of -40°C to 85°C. Certified to AEC-Q200 standards for automotive use.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection by increasing resistance during overcurrent or overheating events
• Self-resetting functionality eliminates the need for physical component replacement after fault clearance
• Automotive-grade construction ensures reliability under rigorous environmental conditions

Ptc Resettable Fuses Applications

• Automotive electronic systems requiring AEC-Q200 certified protection
• Portable consumer electronics circuits
• Communication equipment power lines

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'AF2B' against official manufacturer documentation to confirm exact packaging and tape-and-reel specifications. Ensure compatibility with standard SMT reflow profiles and check for any recent product change notices that may affect lead times or material composition prior to final procurement authorization.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile 1812 footprint is required for space-constrained designs. The 200 mA hold current suits sensitive signal or low-power data lines. Confirm that the 60V rating exceeds the system's maximum operating voltage and that the 5 Ohm trip resistance allows for acceptable leakage current levels in the protected circuit.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZCG family of Surface Mount Technology (SMT) Low Profile PTC Resettable Fuses. The series is characterized by its compact dimensions and high current-carrying capability relative to its size. It serves as a reusable alternative to traditional one-time fuses in modern PCB layouts.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 0ZCG series variants with matching 200 mA hold current and 60V ratings, such as 0ZCG0200AF2C, provided the packaging format aligns with assembly requirements.
