Inrush Current Limiters (ICL) Procurement Notes

Verify the specific Beta constant and tolerance class against the manufacturer datasheet prior to integration. Confirm that the steady-state current rating of 7 A aligns with the application's operational requirements. Ensure the physical dimensions fit the designated PCB footprint or mounting area. Cross-reference the RoHS compliance status if environmental regulations apply to the final product assembly.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required nominal resistance of 3 Ohms and the specific Beta value of 2750 K for accurate temperature-resistance mapping. Consider the 15 mm size constraint when designing the mechanical layout. Evaluate the maximum allowable steady-state current to ensure the device does not exceed its thermal limits during continuous operation. Compare alternative part numbers within the ICL family if different resistance values or physical sizes are needed.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of NTC thermistors designed specifically for inrush current limiting. These components are widely used in electronic equipment to protect sensitive downstream circuitry from high initial charging currents. The series offers various resistance values and physical sizes to accommodate different power levels and form factors.

Inrush Current Limiters (ICL) Replacement Considerations

Compatible substitutes include other Eaton ICL series parts with matching electrical parameters, such as the ICL301D09MIB, provided the physical dimensions and current ratings are compatible. Verify that any replacement maintains the same Beta value and tolerance specifications to ensure consistent performance in the circuit.
