It features a ceramic body with a nominal resistance of 1.3 Ohms and a tolerance of ±20%. The component has a power rating of 4 W and a maximum steady-state current rating of 8 A. It operates within a temperature range of -40°C to +200°C. Physical dimensions include an 18 mm diameter, 6.5 mm width, and a 7.5 mm lead spacing.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current suppression during power-up sequences
• Utilizes high thermal stability ceramic construction for reliable operation
• Supports continuous high-current loads up to 8 Amperes

Inrush Current Limiters (ICL) Applications

• Power supply input stages for surge protection
• Motor drive circuits requiring soft-start capabilities
• Transformer primary side inrush limitation

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'F' against official manufacturer documentation to confirm packaging or marking variations. Confirm that the 4 W power rating and 8 A current limits align with your circuit's thermal requirements. Ensure the operating temperature range meets environmental specifications. Cross-reference the datasheet for precise resistance values at standard temperatures.

Inrush Current Limiters (ICL) Selection Notes

Select this component when high peak current absorption is required during system initialization. The 1.3 Ohm initial resistance effectively limits charging currents for capacitive loads. Consider the 4 W dissipation capability for sustained operational heat management. Verify compatibility with PCB mounting constraints due to the radial lead configuration and physical footprint.

Inrush Current Limiters (ICL) Part Context

This part belongs to the YAGEO SP series of NTC thermistors, which are specialized for inrush current limiting rather than temperature sensing. Unlike general-purpose NTCs, these components are engineered to withstand significant energy pulses without degradation. The series offers various resistance and current ratings to match different power levels.

Inrush Current Limiters (ICL) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Direct replacement requires matching the 1.3 Ohm resistance, 4 W power rating, 8 A current capacity, and radial package dimensions. Consult manufacturer cross-reference guides for equivalent SP series variants.
