Inrush Current Limiters (ICL) Procurement Notes

Verify the specific resistance value and package dimensions against the official TDK Electronics datasheet before integration. Confirm that the 7.5 A maximum current rating aligns with the target circuit's operational requirements. Ensure compliance with relevant safety standards such as IEC 60068-2-78 for the intended environment. Cross-reference the lead spacing and physical footprint with the PCB layout to guarantee mechanical compatibility.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a robust solution for limiting inrush current in AC or DC input lines is required. The 10 Ω resistance value provides a balance between surge suppression and steady-state power loss. Consider the 100 s thermal time constant for recovery periods between switching cycles. Verify that the operating temperature range of -55°C to 170°C meets the environmental conditions of the final assembly.
