NTG04-012LF

Inrush Current Limiters (ICL) Overview

The NTG04-012LF is an NTC thermistor inrush current limiter from the YAGEO NT series. It features a nominal resistance of 12 Ohms with a tolerance of ±15%. The component supports a maximum steady-state current of 4 A and has a physical diameter of 16.00 mm (0.630 inches). Designed for robust thermal management, it operates within a temperature range of -40°C to +85°C.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limiting during power-up sequences
• Utilizes negative temperature coefficient characteristics for self-regulating resistance
• Offers reliable protection against high initial surge currents

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Motor drive circuits
• Transformer primary side protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributors before integration. Confirm that the 12 Ohm resistance and 4 A current rating align precisely with the target circuit's surge requirements. Ensure the 16 mm package size fits the designated PCB footprint and thermal constraints.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 12 Ohm initial resistance is required to limit peak charging currents. The 4 A continuous current rating suits moderate-power applications. Consider the 16 mm diameter for adequate heat dissipation. Evaluate the -40°C to +85°C operating range against environmental conditions. Compare with similar NT series parts if different resistance values are needed.
