Ptc Resettable Fuses Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Littelfuse documentation. Confirm that the received items match the specified picoSMD series characteristics and package details. Ensure compliance with RoHS requirements as indicated in the product specifications before integration into production lines.

Ptc Resettable Fuses Selection Notes

Select this component when circuit protection is required for low-voltage applications up to 6 VDC. The 1.1 A hold current suits moderate load scenarios, while the 40 A interrupting rating handles significant fault currents. Consider the small footprint and SMT compatibility for dense board layouts requiring reliable thermal response.

Ptc Resettable Fuses Part Context

This device belongs to the picoSMD family of subminiature surface mount fuses. It is engineered specifically for protecting circuits in space-constrained environments where traditional fuses cannot fit. The PolySwitch technology offers repeated use capability compared to single-use alternatives, enhancing system reliability.
