Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix matches the required voltage and current ratings before procurement. Confirm that the radial lead configuration aligns with the target PCB footprint design. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the datasheet specifications against the application's peak surge currents to prevent nuisance tripping during normal operation.

Ptc Resettable Fuses Selection Notes

Select this component when a 130V rated resettable fuse is required for through-hole implementations. The 300mA hold current defines the continuous operational limit, while the 600mA trip current indicates fault response thresholds. Consider the 1.3 Ohm initial resistance impact on low-voltage circuits. Evaluate the thermal derating curves if ambient temperatures approach the upper operational limit of 85°C.

Ptc Resettable Fuses Part Context

This part belongs to the BK130 series of PPTC resettable fuses manufactured by YAGEO. The series offers various voltage ratings including 16V, 30V, 60V, 130V, 250V, and 500V options. These components are commonly used in conjunction with other circuit protection devices like TVS diodes and MOVs to provide comprehensive electrical safety solutions across multiple industries.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 130V rating and 300mA hold current specification. Verify that alternative parts maintain similar trip characteristics and physical dimensions for board compatibility. Check for equivalent lead spacing and package style to ensure seamless integration without redesigning the mounting holes or traces.
