Ptc Resettable Fuses Procurement Notes

Verify the manufacturer designation as TDK, noting that EPCOS entities have been rebranded under the TDK name globally. Confirm the specific ordering suffix matches the required electrical parameters, particularly the 250 mA hold current and 30V rating. Ensure the package type corresponds to the radial leaded configuration. Check for RoHS compliance status and confirm the moisture sensitivity level classification prior to procurement.

Ptc Resettable Fuses Selection Notes

Select this component when designing circuits requiring resettable overcurrent protection in low-voltage environments up to 30V. The 250 mA hold current suits applications with steady-state currents below this threshold. Consider the 4.6 Ohm initial resistance for impact on circuit biasing. Verify that the operating temperature range of -40°C to 85°C aligns with the environmental conditions of the target application.

Ptc Resettable Fuses Part Context

This part belongs to the B59985 series of PTC thermistors from TDK. It serves as a protective element distinct from temperature sensing components like the B59885 series. The series is engineered for robust circuit protection in demanding sectors, leveraging TDK's expertise in electronic components following the integration of EPCOS technologies.
