Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'A-2' against official Bourns documentation to confirm exact lead time and availability status. Ensure the procurement channel provides genuine components with traceable manufacturing data. Confirm compliance with current RoHS directives and conflict mineral reporting requirements before finalizing orders.

Ptc Resettable Fuses Selection Notes

Select this component when circuit protection requires reliability under continuous high-temperature exposure. The 150 mA holding current suits low-power signal or control lines. Verify that the 60 VDC rating aligns with the system's maximum operating voltage. Consider the physical package size constraints and mounting requirements during PCB layout design.

Ptc Resettable Fuses Part Context

This part belongs to the MF-USHT series of high-temperature PPTC resettable fuses. These devices utilize proprietary polymer technology to deliver robust protection where standard PTCs may fail due to thermal degradation. The series is specifically engineered to maintain stability and performance in applications exceeding typical commercial temperature limits.

Ptc Resettable Fuses Replacement Considerations

Consult official Bourns substitution guides for verified equivalents. Generic PTC replacements may not match the high-temperature stability or specific trip characteristics required for this application. Validate any substitute against the original datasheet parameters to ensure circuit safety and compliance.

Ptc Resettable Fuses FAQ

What is the difference between holding current and tripping current for this device?

Holding current (150 mA) is the maximum current the device will allow without tripping at 25°C. Tripping current (300 mA) is the minimum current that will cause the device to switch to a high-resistance state within a specified time.

Is this component suitable for AC circuits?

The datasheet specifies a maximum voltage rating of 60 VDC. While PPTCs can function in AC, verify if the AC voltage peak exceeds the DC rating and consult official documentation for AC-specific derating guidelines.
