Ptc Resettable Fuses Procurement Notes

Verify that the specific part number FSMD035-1206-R matches the required 16V rating and 350mA hold current for your design. Confirm the package type is strictly 1206 SMD. Ensure the supplier provides official datasheets confirming RoHS compliance and halogen-free status. Check that the component is sourced from authorized channels to guarantee authenticity and performance consistency.

Ptc Resettable Fuses Selection Notes

Select this component when a low-voltage, fast-acting resettable fuse is needed for space-constrained applications. The 1206 size offers a balance between holding current capacity and board area efficiency. Consider the 16V maximum voltage limit to ensure it exceeds the circuit's operating voltage. Evaluate the thermal environment to ensure the 85°C maximum operating temperature is sufficient for the application.
