BK250-080-DZ

Ptc Resettable Fuses Overview

The YAGEO BK250-080-DZ is a polymer PTC resettable fuse from the BK250 series, designed for through-hole PCB mounting. It features a radial disc package with a 7.4mm diameter and 13.5mm height. The component has a maximum voltage rating of 250V, a hold current of 80mA, and a trip current of 160mA. Its initial resistance is typically 13 Ohms, with a maximum rated current of 3A. It operates within a temperature range of -40°C to +85°C and utilizes a 5.1mm lead spacing.

Ptc Resettable Fuses Feature Summary

• Provides automatic self-resetting overcurrent protection via polymeric positive temperature coefficient technology.
• Offers dual certification from UL and CSA for international safety compliance.
• Features a compact radial disc form factor suitable for space-constrained printed circuit board layouts.

Ptc Resettable Fuses Applications

• Overcurrent protection in portable electronic devices
• Protection circuits for peripheral interfaces such as USB and IEEE 1394

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix DZ corresponds to the required packaging configuration and regulatory certifications. Confirm that the hold current and trip current parameters align with the target circuit's operational limits. Ensure the maximum voltage rating meets the system requirements. Check for RoHS compliance status if restricted substances are prohibited in the assembly process.

Ptc Resettable Fuses Selection Notes

Select this component when a low-current, high-voltage resettable fuse is required for radial mounting. The 80mA hold current suits sensitive signal lines or low-power control circuits. Consider the higher initial resistance compared to square packages when calculating voltage drop. Evaluate the thermal environment to ensure the device trips reliably without nuisance tripping during normal operation peaks.

Ptc Resettable Fuses Part Context

This part belongs to the YAGEO BK250 series of resettable fuses, which are widely used for circuit protection. The series offers various current ratings and package styles, including disc and square forms. The BK250-080-DZ specifically addresses applications needing moderate voltage tolerance with precise low-current protection capabilities in a standard radial footprint.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other BK250 series variants with similar electrical characteristics, such as BK250-060-DZ or BK250-100-DZ, provided the hold and trip currents match the design requirements. Cross-reference physical dimensions to ensure compatibility with existing PCB footprints.
