NTG07-002L

Inrush Current Limiters (ICL) Overview

The NTG07-002L is a Negative Temperature Coefficient (NTC) thermistor functioning as an inrush current limiter. It features a nominal resistance of 2 Ohms with a tolerance of ±15%. The device supports a maximum steady-state current of 7 Amperes and exhibits a hot resistance of 74 mOhms at that current level. The component has a cylindrical body diameter of 0.512 inches (13.00 mm) and a lead spacing of 0.295 inches (7.50 mm).

Inrush Current Limiters (ICL) Feature Summary

• Provides automatic reduction of high initial surge currents during power-up phases.
• Utilizes negative temperature coefficient characteristics to transition from high resistance to low resistance.
• Designed for repeated cycling applications without requiring manual reset mechanisms.

Inrush Current Limiters (ICL) Applications

• Power supply input stages for surge protection
• Motor drive circuits for inrush limitation
• Transformer primary side protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific application current requirements against the 7 A steady-state rating to ensure thermal stability. Confirm that the 2 Ohm initial resistance aligns with the target inrush current suppression levels for the circuit design. Ensure adequate clearance for the 13 mm diameter and 7.5 mm lead spacing on the PCB layout.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a non-resettable, passive solution for limiting startup current spikes is required. The 2 Ohm resistance value determines the peak current limitation capability. Consider the physical dimensions and lead configuration for mechanical integration into the assembly.
