Inrush Current Limiters (ICL) Procurement Notes

Verify the specific thermal characteristics and maximum energy absorption ratings against your circuit requirements before ordering. Confirm that the 250 Ohm initial resistance aligns with your inrush current specifications. Ensure the physical dimensions fit your PCB layout constraints. Check for any updated datasheet revisions regarding operating temperature limits.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a fixed initial resistance of 250 Ohms is required to limit startup current. Consider the ±30% tolerance impact on peak inrush current calculations. Evaluate the thermal dissipation capabilities relative to the frequency of power cycles. Compare with other series if higher or lower initial resistance is needed.
