N25SP004M

Inrush Current Limiters (ICL) Overview

The YAGEO N25SP004M is a Negative Temperature Coefficient (NTC) thermistor designed for inrush current limiting applications. It features a nominal resistance of 4 Ohms with a tolerance of ±20% and a continuous power rating of 6.5 W. The component supports a maximum steady-state current of 14 A and operates within a temperature range of -40°C to +200°C. It utilizes a radial PCB mount configuration with a lead spacing of 7.5 mm, measuring 29 mm in diameter and 7.5 mm in width.

Inrush Current Limiters (ICL) Feature Summary

• Effectively restrains surge currents during system startup
• Maintains low power loss under stable operating conditions
• Provides wide over-current control range with fast response characteristics

Inrush Current Limiters (ICL) Applications

• Inrush current limiting in power supply circuits
• Surge protection for electronic equipment
• Over-current protection in industrial control systems

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix designation when sourcing, as variants such as N25SP004M-F exist with identical electrical parameters but potentially different packaging or marking standards. Confirm that the required 4 Ohm resistance and 14 A current rating align with the circuit design specifications before procurement. Ensure compatibility with the specified radial lead spacing and PCB mounting requirements.

Inrush Current Limiters (ICL) Selection Notes

Select this component for applications requiring robust inrush current suppression with high thermal endurance up to 200°C. The 6.5 W power rating and 14 A current capacity suit moderate-to-high power electronics. Consider the 20% resistance tolerance for circuit design margins. Verify that the physical dimensions fit the available PCB real estate and that the radial termination style matches the assembly process.

Inrush Current Limiters (ICL) Part Context

This part belongs to the YAGEO SP series of NTC thermistors, specifically engineered for inrush current limiting. The series offers various resistance values and current ratings to accommodate different power levels. The N25SP004M represents a mid-range option in terms of resistance, balancing effective surge limitation with minimal steady-state voltage drop.

Inrush Current Limiters (ICL) Replacement Considerations

The N25SP004M-F is a confirmed substitute with identical electrical specifications including 4 Ohms resistance and 14 A current rating. Both parts share the same 6.5 W power rating and operational temperature range. Verify mechanical footprint compatibility if switching between standard and factory-packaged variants.
