BK250-2000-SZ

Ptc Resettable Fuses Overview

The YAGEO BK250-2000-SZ is a polymeric positive temperature coefficient (PPTC) resettable fuse designed for PCB mounting. It features a radial lead configuration with a 10.20 mm lead spacing. The component operates within a voltage range up to 250 V and maintains a holding current of 180 mA, tripping at 540 mA. It supports a maximum current of 10 A and exhibits an initial resistance of 3 Ohms. The device functions reliably between -40°C and +85°C.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection through self-resetting polymer technology
• Features radial leads for standard printed circuit board integration
• Ensures reliable operation across extended industrial temperature ranges

Ptc Resettable Fuses Applications

• Overcurrent protection in consumer electronics assemblies
• Signal line protection in communication equipment
• Power supply circuit safeguarding in industrial control systems

Ptc Resettable Fuses Procurement Notes

Verify the specific package variant against official datasheets, as suffixes may indicate distinct physical dimensions or certification levels. Confirm that the radial lead spacing matches the target PCB footprint requirements. Ensure compliance with RoHS directives if environmental regulations apply to the final assembly. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and availability.

Ptc Resettable Fuses Selection Notes

Select this component when designing circuits requiring high-voltage isolation up to 250 V with moderate current handling capabilities. The 180 mA holding current suits low-power signal lines rather than high-current power rails. Consider the 3 Ohm initial resistance for impact on signal integrity in sensitive applications. Evaluate the thermal environment to ensure the operating temperature range remains within specified limits during continuous duty cycles.

Ptc Resettable Fuses Part Context

This model belongs to the BK250 series of PPTC resettable fuses manufactured by YAGEO. The series offers various current ratings and package styles to accommodate diverse circuit protection needs. The BK250 designation indicates a specific voltage rating and form factor within the broader product line, distinguishing it from lower voltage or surface-mount alternatives.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other BK250 series variants with matching electrical parameters. Verify compatibility with equivalent parts from different manufacturers by comparing holding current, trip current, and maximum voltage ratings. Ensure mechanical fitment aligns with existing PCB layouts before implementing alternative components.
