Procurement Notes

Verify that the specific part number matches your design requirements before ordering. Confirm that the voltage and current ratings align with your system specifications. Check for any specific packaging or reel requirements if using automated placement equipment. Ensure compliance with RoHS directives if required by your manufacturing process. Contact Bourns sales representatives for sample requests or technical support regarding integration.

Selection Notes

Select this component based on its resettable nature which eliminates the need for manual fuse replacement after tripping events. Consider the hold current and trip current characteristics relative to your normal operating current and maximum fault current scenarios. Evaluate the physical size constraints of your PCB layout to ensure the surface-mount package fits available space. Assess the thermal environment to confirm the device can operate reliably within expected ambient temperature ranges during both normal and fault conditions.
