BK250-110-SY

Ptc Resettable Fuses Overview

The YAGEO BK250-110-SY is a polymeric PTC resettable fuse designed for through-hole PCB mounting. It features a radial disc package with a 5.1 mm lead spacing. The component has a maximum voltage rating of 250 V and a hold current of 110 mA. Its trip current is specified at 220 mA, with a maximum rated current of 3 A. The initial resistance is typically low, ensuring minimal impact on circuit operation under normal conditions.

Ptc Resettable Fuses Feature Summary

• Provides automatic self-recovery protection against overcurrent conditions without requiring replacement
• Utilizes polymer technology to offer consistent performance across the operating temperature range
• Features a radial disc form factor suitable for standard printed circuit board layouts

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection circuits in consumer audio and video equipment
• Circuit safeguarding in telecommunications hardware

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix SY against official YAGEO documentation to confirm package dimensions and lead configuration. Ensure the selected variant matches the required hold and trip currents for the target application circuit design parameters.

Ptc Resettable Fuses Selection Notes

Select this component when a through-hole solution is required for moderate current protection levels. Compare the 110 mA hold current against the circuit's normal operating current to ensure reliable non-tripping during standard operation while providing adequate fault protection.

Ptc Resettable Fuses Part Context

This part belongs to the BK250 series of resettable fuses from YAGEO. The series offers various hold currents and package styles, including disc and square forms, to accommodate different thermal and spatial constraints in electronic assemblies requiring overcurrent safety compliance.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other BK250 series variants with identical electrical ratings but different suffixes indicating package variations, such as BK250-110-DZ or BK250-110-SZ, provided the physical footprint and lead spacing are compatible with the existing PCB layout.
