Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'DY' against official YAGEO documentation to confirm lead frame material and plating specifications. Ensure the selected variant matches the required thermal characteristics for the target application environment. Cross-reference the datasheet revision date to guarantee access to the most current electrical parameters and mechanical drawings before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when circuit design requires a low hold current of 60 mA for sensitive signal lines or low-power devices. The 250 V rating suits general-purpose AC/DC applications. Engineers must ensure the expected operating current remains below the 60 mA threshold to prevent nuisance tripping during normal operation while allowing sufficient margin for transient surges.

Ptc Resettable Fuses Part Context

This device belongs to the BK250 series of square-shaped PPTC resettable fuses manufactured by YAGEO. The series offers various hold current options ranging from 30 mA to higher values, all sharing similar voltage ratings and mounting configurations. The BK250-060-DY represents the lower end of the current spectrum within this family, optimized for precise protection needs.
