Inrush Current Limiters (ICL) Procurement Notes

Verify the specific Beta constant and tolerance requirements against the design specifications before procurement. Confirm that the 15 mm package dimension fits the intended PCB layout. Ensure the 3 A current rating meets the operational demands of the target circuit. Check for RoHS3 compliance if required by project regulations. Validate the manufacturer part number against official Eaton documentation.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 47 Ohm cold resistance is required for inrush limiting. Consider the 3300 K Beta value for thermal response characteristics. Evaluate the 15 mm size constraint for mechanical integration. Assess the ±20% resistance tolerance against circuit sensitivity. Verify compatibility with the intended operating temperature range.
