NTE03-019MF

Inrush Current Limiters (ICL) Overview

The YAGEO NTE03-019MF is an NTC thermistor designed for inrush current limiting applications. It features a nominal resistance of 19 Ohms with a tolerance of ±20%. The component supports a maximum steady-state current of 3 Amperes and has a physical diameter of 13.50 mm (0.531 inches). It belongs to the NT series and is supplied in bulk packaging.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter to protect electronic circuits during power-up
• Utilizes negative temperature coefficient characteristics for self-regulating resistance
• Constructed for radial lead mounting in through-hole applications

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer protection circuits
• Motor drive inrush control

Inrush Current Limiters (ICL) Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official YAGEO documentation. Confirm that the specific suffix matches the required electrical parameters, particularly the 19 Ohm resistance value and 3 Ampere current rating, before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component when circuit design requires a 19 Ohm initial impedance to limit peak charging currents. Ensure the operating environment accommodates the thermal profile associated with a 3 Ampere steady-state current capacity and verify compatibility with standard through-hole assembly processes.

Inrush Current Limiters (ICL) Part Context

This device is part of the YAGEO NT series of NTC thermistors. These components are specifically engineered for inrush current limiting duties rather than general temperature sensing. The product line emphasizes reliability in protecting sensitive downstream electronics from high initial surge currents common in capacitive loads.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 19 Ohm nominal resistance, ±20% tolerance, and 3 A current rating. Verify that alternative components maintain the same 13.50 mm diameter and radial lead configuration to ensure mechanical fit within existing PCB footprints.
