BK60-025-DZ

Ptc Resettable Fuses Overview

The YAGEO BK60-025-DZ is a radial leaded polymeric positive temperature coefficient (PPTC) resettable fuse from the BK60 series. Designed for through-hole mounting, this component features a round disc package with a diameter of 7.4 mm and a length of 12.7 mm. It operates within a maximum voltage of 60 V and maintains a hold current of 250 mA, with a trip current of 500 mA. The device supports a maximum fault current of 40 A and exhibits a minimum resistance of 80 mΩ. It functions reliably across an operating temperature range of -40 °C to +85 °C, with a power dissipation rating of 450 mW.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection by increasing resistance in response to overcurrent conditions
• Features a self-resetting mechanism that restores normal operation after cooling
• Utilizes a robust radial leaded construction suitable for through-hole PCB integration

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection circuits in consumer electronics assemblies
• Battery pack safeguarding applications

Ptc Resettable Fuses Procurement Notes

Verify the specific hold current and trip current ratings against the official YAGEO datasheet to ensure compatibility with the target circuit design. Confirm that the maximum voltage and fault current capabilities meet the system requirements. Check for RoHS compliance status and verify the package dimensions match the intended PCB footprint before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable protection solution is required for low-voltage DC circuits. Ensure the hold current exceeds the normal operating current while the trip current remains below the maximum allowable fault level. Consider the thermal environment and power dissipation limits to prevent nuisance tripping during steady-state operation or transient surges.

Ptc Resettable Fuses Part Context

This part belongs to the YAGEO BK60 series of PPTC resettable fuses, which are widely used for secondary protection in various electronic systems. The series offers multiple current ratings to accommodate different circuit needs. The BK60-025-DZ specifically targets applications requiring a 250 mA hold current, providing a balance between sensitivity and durability for standard consumer and industrial electronics.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other YAGEO BK60 series variants with similar electrical characteristics, such as the BK60-030-DZ for slightly higher current handling. Cross-brand replacements require matching voltage, hold current, trip current, and physical package dimensions to ensure functional equivalence.
