Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'M000' against official TDK documentation to confirm package type and compliance status. Ensure the application circuit design accounts for the 6 A steady-state current limit and thermal dissipation requirements. Confirm that the 7 Ohm resistance value aligns with the system's inrush current specifications before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 7 Ohm initial resistance is required to limit peak charging currents. The 6 A current rating suits applications with moderate power demands. Consider the 16 mm disc size for mechanical clearance. Verify that the operating environment stays within the specified -55°C to +170°C range to ensure reliable performance and longevity.
