Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required thermal and electrical specifications. Confirm that the silicone resin coating meets the environmental standards of the target application. Cross-reference the 1 Ohm resistance value and 5 A current rating with circuit design requirements to prevent under-specification or unnecessary cost.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a compact 11mm diameter NTC thermistor is required for inrush current protection. Ensure the operating environment stays within the -40°C to 175°C range. Verify that the 1 Ohm resistance provides adequate limiting for the specific load without excessive power dissipation during normal operation. Consider the ±20% tolerance for circuit stability margins.
