NTD04-007M

Inrush Current Limiters (ICL) Overview

The NTD04-007M is an NTC thermistor from the YAGEO SP series, designed for inrush current limiting. It features a nominal resistance of 7 Ohms with a tolerance of ±20%. The component has a steady-state current rating of 4 A and a power rating of 2.5 W. It utilizes radial leads with a 5 mm spacing and measures 8 mm in diameter. The operating temperature range spans from -40°C to +170°C.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limitation during power-up sequences
• Utilizes negative temperature coefficient characteristics for self-regulating resistance
• Features radial leaded construction for through-hole PCB mounting

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Motor drive circuits
• Transformer protection systems

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for thermal derating curves and maximum energy absorption ratings before integration. Confirm that the 4 A steady-state current rating aligns with the application's continuous load requirements. Ensure the 7 Ohm initial resistance does not cause excessive voltage drop during normal operation. Check RoHS compliance status if required by project specifications.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a compact 8 mm form factor is required for inrush limiting applications. The 7 Ohm resistance value suits moderate current loads up to 4 A. Consider the ±20% tolerance for circuit design margins. Compare against larger series parts like N25SP007M if higher current handling or lower resistance is needed.

Inrush Current Limiters (ICL) Part Context

This part belongs to the YAGEO SP series of NTC thermistors. It shares the same 7 Ohm base resistance as other models in the lineup but differs in physical size and current capacity. The NTD04 variant offers a balance between size and performance for general-purpose electronics protection.

Inrush Current Limiters (ICL) Replacement Considerations

NTB02-007MV serves as a comparable alternative with similar resistance but lower current rating (2 A). For higher current needs, consider the N25SP007M which supports 10 A. Verify lead spacing and dimensional compatibility before substitution.
