NTJ09-003LF

Inrush Current Limiters (ICL) Overview

The YAGEO NTJ09-003LF is a lead-free inrush current limiter (ICL) belonging to the NTJ series. It features a radial leaded package with an 18mm diameter body and a standard 7.5mm lead spacing. The component provides a nominal cold resistance of 3 Ohms with a tolerance of ±20%. It is rated for a maximum steady-state current of 9 Amperes, ensuring reliable operation within specified thermal limits.

Inrush Current Limiters (ICL) Feature Summary

• Provides high initial impedance to suppress surge currents during power-up
• Automatically transitions to low-resistance state as temperature increases
• Supports continuous operation under defined steady-state current conditions

Inrush Current Limiters (ICL) Applications

• Power supply input stages
