Inrush Current Limiters (ICL) Procurement Notes

Verify the specific part number suffix against official Vishay documentation to ensure correct tolerance and thermal characteristics. Confirm that the 8 A current rating aligns with the system's operational requirements. Check for RoHS compliance status if required by manufacturing standards. Ensure PCB layout accommodates the 23 mm diameter and 7.8 mm lead spacing. Validate that the 10 Ohm resistance value meets the design's inrush limiting specifications.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 10 Ohm nominal resistance and 8 A continuous current capacity are required for inrush limiting. Consider the 23 mm body size for adequate heat dissipation in the target enclosure. Ensure the operating environment does not exceed the maximum voltage ratings specified for the MS22 series. Verify compatibility with the intended PCB mounting style and lead dimensions.

Inrush Current Limiters (ICL) Part Context

The MS2210008 is part of the Vishay Ametherm MegaSurge MS22 series of inrush current limiters. These components are engineered to protect sensitive electronic circuits from damage caused by high initial charging currents. The series offers various resistance and current ratings to suit different power levels. The MS22 variant specifically targets applications requiring robust surge protection with standard through-hole integration.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include the MS2210008B, which shares identical electrical parameters. When replacing, verify that the physical dimensions and lead spacing match the existing PCB footprint. Ensure the replacement component maintains the same UL approval status and voltage ratings. Cross-reference datasheets to confirm thermal performance matches the original design requirements.
