NTE03-021MF

Inrush Current Limiters (ICL) Overview

The YAGEO NTE03-021MF is a Negative Temperature Coefficient (NTC) thermistor designed for inrush current limiting applications. It features a nominal resistance of 21 Ohms with a tolerance of ±20%. The component supports a maximum steady-state current of 3 Amperes and has a body diameter of 13.50 mm (0.531 inches). It utilizes radial leads for through-hole mounting, providing a reliable solution for protecting electronic circuits from high initial surge currents during power-up phases.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter to protect sensitive circuit components
• Utilizes negative temperature coefficient characteristics for automatic resistance adjustment
• Features radial lead configuration for standard printed circuit board integration

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for thermal dissipation curves and time-current characteristics before finalizing the design. Confirm that the 3 A steady-state rating aligns with the operational requirements of the target application. Ensure proper PCB spacing is maintained to accommodate the 13.50 mm body diameter and lead pitch. Cross-reference the manufacturer's latest compliance documentation for RoHS and REACH standards.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 21 Ohm initial resistance is required to limit surge current effectively. Consider the 3 A continuous current capacity against the expected load profile. Evaluate the thermal environment to ensure the device can dissipate heat generated during the cooling phase. Compare physical dimensions against available board space constraints.

Inrush Current Limiters (ICL) Part Context

This part belongs to the NT series of NTC thermistors manufactured by YAGEO. These devices are specialized for managing electrical transients rather than precision temperature sensing. The product line focuses on robustness and reliability in high-energy switching environments common in modern power electronics.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 21 Ohm resistance, 3 A current rating, and 13.50 mm diameter. Verify lead spacing compatibility to ensure mechanical fit without redesigning the footprint.
