Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix and tolerance requirements against the official YAGEO datasheet before procurement. Confirm that the 3 Ohm resistance and 15 Ampere current ratings align with the target circuit design parameters. Ensure compatibility with the specified 29 mm diameter and radial lead spacing for the intended PCB layout. Check regional availability and shipping restrictions as distribution status may vary by location.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 3 Ohm initial resistance is required to limit high inrush currents up to 15 Amperes. The 6.5 W power rating supports high-energy dissipation needs typical in larger power stages. The wide operating temperature range ensures reliability in demanding environments. Verify that the physical footprint fits the assembly constraints due to the 29 mm diameter size.

Inrush Current Limiters (ICL) Part Context

This part belongs to the YAGEO SP series of NTC thermistors, specifically engineered for inrush current limiting. These components are distinct from standard temperature sensing thermistors by their ability to handle high transient currents while providing significant resistance at cold start conditions. The SP series is widely used in power electronics to protect sensitive downstream components from startup surges.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes within the same series include N25SP002L-F (2 Ohm) and N25SP001M-F (1 Ohm). For higher resistance requirements, consider models outside this specific diameter class. Always verify that alternative parts match the 15 A current rating and 6.5 W power dissipation capabilities to ensure equivalent performance.
