NTG04-018LF

Inrush Current Limiters (ICL) Overview

The NTG04-018LF is a Negative Temperature Coefficient (NTC) thermistor manufactured by YAGEO, designed for inrush current limiting applications. It features an 8mm package size and provides a nominal resistance of 18 Ohms with a tolerance of ±15%. The component supports a maximum steady-state current of 4 Amperes and operates within a temperature range of -40°C to +125°C.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limitation during power-up sequences
• Utilizes NTC material properties to reduce resistance as temperature increases
• Designed for robust protection against high initial surge currents

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Consumer electronics power circuits
• Industrial equipment surge protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for thermal derating curves and mechanical dimensions. Confirm that the 18 Ohm resistance value aligns with the target circuit's surge requirements. Ensure the 4A current rating exceeds the expected operating load to prevent component failure.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a low-resistance inrush limiter is required for higher current loads. Compare against standard 6 Ohm variants if lower initial impedance is needed. Verify package compatibility with the PCB layout and ensure adequate spacing for thermal dissipation during operation.

Inrush Current Limiters (ICL) Part Context

This part belongs to the NT series of NTC thermistors from YAGEO. These components are specifically engineered for inrush current limiting rather than temperature sensing. They serve as critical passive elements in protecting sensitive downstream circuitry from damaging startup surges.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other 18 Ohm, 4A NTC inrush limiters from manufacturers such as EPCOS or Vishay. Ensure replacement parts match the 8mm form factor and electrical ratings for seamless integration.
