NTD04-003LF

Inrush Current Limiters (ICL) Overview

The NTD04-003LF is an NTC thermistor from the NT series, designed as an inrush current limiter. It features a nominal resistance of 3 Ohms with a tolerance of ±15% and supports a maximum steady-state current of 4 A. The component has an 8 mm (0.433 inch) diameter and utilizes a bulk packaging format.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter to protect circuits during power-up
• Utilizes Negative Temperature Coefficient (NTC) technology for rapid resistance reduction after startup

Inrush Current Limiters (ICL) Applications

• Power supply input protection
• Motor drive circuit protection
• Transformer inrush current limiting

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'LF' against the manufacturer's official datasheet to confirm lead-free compliance status. Confirm that the 3 Ohm resistance value aligns with the target circuit's inrush current requirements. Ensure the 4 A steady-state current rating exceeds the operational load to prevent thermal failure.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a compact 8 mm form factor is required for inrush suppression. Compare the 3 Ohm initial resistance against alternative values like 6 Ohms to balance peak current limitation versus steady-state power loss. Verify compatibility with the specific voltage ratings of the application environment.
