Inrush Current Limiters (ICL) Procurement Notes

Verify the specific Beta constant and tolerance requirements against the application design specifications before procurement. Confirm that the 1 A steady-state current rating aligns with the operational load conditions. Ensure the 9 mm package dimensions fit within the designated PCB layout constraints. Cross-reference the manufacturer datasheet for thermal derating curves and maximum energy absorption limits to guarantee reliable long-term performance under expected surge conditions.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 60 Ohm initial resistance is required to limit peak charging currents effectively. Consider the 3150 K Beta value for accurate temperature-resistance modeling in the target environment. Evaluate the 1 A current rating against the circuit's continuous operating current to prevent overheating. Assess the 9 mm form factor for mechanical compatibility with the assembly process and available board space.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of inrush current limiters, which are specialized NTC thermistors. These components are engineered to protect sensitive electronic circuits from high initial charging currents during power-up. The series offers various resistance values and sizes to accommodate different power levels and physical constraints in consumer electronics and industrial power supplies.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 60 Ohm resistance, 1 A current rating, and 9 mm size. Verify equivalent Beta constants and tolerance grades to ensure identical thermal behavior. Check lead type and package style for mechanical interchangeability without redesigning the footprint.
