Ptc Resettable Fuses Procurement Notes
Verify the specific voltage suffix (e.g., K-1 vs K-240) against system requirements, as ratings vary. Confirm RoHS compliance status for the specific production batch. Ensure PCB pad dimensions match the radial lead spacing and disc package size. Check for obsolescence notices or PCNs before finalizing procurement plans.
Ptc Resettable Fuses Selection Notes
Select this component when a radial-leaded, line-voltage rated resettable fuse is required. Compare the 750 mA hold current against normal operating loads. Verify that the 240 VAC rating aligns with the circuit's maximum voltage. Consider thermal derating if ambient temperatures exceed standard limits.
Ptc Resettable Fuses Part Context
This part belongs to the Littelfuse LVR series of PolySwitch resettable fuses. These devices are characterized by their radial lead configuration and suitability for high-voltage AC/DC line applications. The series offers a broad range of current ratings from 50mA to 2A for various industrial and consumer electronics.
