NTG04-019LF

Inrush Current Limiters (ICL) Overview

The YAGEO NTG04-019LF is a Negative Temperature Coefficient (NTC) thermistor classified as an Inrush Current Limiter (ICL). It features a nominal resistance of 19 Ohms at 25°C with a tolerance of ±15%. The component supports a maximum steady-state current of 4 A and exhibits a hot resistance of 265 mOhms when carrying that current. Physically, it has a diameter of 16 mm (0.630 inches).

Inrush Current Limiters (ICL) Feature Summary

• Provides inrush current limiting functionality to protect downstream circuit components during power-up phases.
• Utilizes NTC material properties to automatically reduce resistance as temperature increases under load.
• Designed for high-current applications requiring robust thermal management and stable electrical performance.

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix and package type against the manufacturer's latest datasheet to ensure compatibility with assembly processes. Confirm RoHS compliance status and environmental declarations prior to integration into final products.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required nominal resistance value and maximum steady-state current rating. Ensure the physical dimensions fit the available board space and that the thermal characteristics align with the application's operating environment.

Inrush Current Limiters (ICL) Part Context

This part belongs to the NT series of NTC thermistors manufactured by YAGEO. These devices are specifically engineered for inrush current limiting duties rather than general-purpose temperature sensing, distinguishing them from standard thermistor types within the broader product portfolio.
