NTG05-009LF

Inrush Current Limiters (ICL) Overview

The NTG05-009LF is a lead-free inrush current limiter from YAGEO's NT series. It features a nominal resistance of 9 Ohms with ±15% tolerance and a maximum steady-state current rating of 5 A. The component has a diameter of 0.630 inches (16.00 mm) and a lead spacing of 0.295 inches (7.50 mm). Its low-resistance state at rated current is 163 mOhms, providing efficient power handling for circuit protection applications.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective limitation of high inrush currents during power-up sequences to protect sensitive components.
• Automatically transitions from high initial resistance to a low steady-state resistance upon heating.
• Designed for robust performance in general-purpose electronic equipment requiring surge suppression.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Consumer electronics devices
• Industrial control systems

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for thermal characteristics and derating curves before finalizing the design. Confirm that the 5 A steady-state current rating aligns with the application's continuous load requirements. Ensure the physical dimensions fit the target PCB layout constraints.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required nominal resistance value of 9 Ohms and the 5 A current capacity. Consider the thermal environment and the need for lead-free compliance if RoHS standards are mandatory for the end product.
