N15SP003L

Inrush Current Limiters (ICL) Overview

The YAGEO N15SP003L is a Negative Temperature Coefficient (NTC) thermistor designed for inrush current limiting applications. It features a radial leaded package with a diameter of 18 mm and a width of 6.5 mm. The component has a nominal resistance of 3 Ohms with a tolerance of 15%. It supports a continuous current rating of 7 A and a power rating of 4 W. The operating temperature range extends from -40°C to +200°C, with a lead spacing of 7.5 mm.

Inrush Current Limiters (ICL) Feature Summary

• Radial leaded construction for PCB mounting
• High current handling capability up to 7 A
• Wide operational temperature range from -40°C to +200°C

Inrush Current Limiters (ICL) Applications

• Inrush current limiting in power supplies
• Protection of electronic circuits against surge currents
• Temperature compensation in high-power devices

Inrush Current Limiters (ICL) Procurement Notes

Verify the current availability status as this component may be subject to discontinuation or limited supply conditions. Confirm that the radial lead pitch matches the target PCB layout requirements. Ensure the thermal management design accommodates the 4 W power rating and 7 A current capacity during peak operation to prevent overheating.

Inrush Current Limiters (ICL) Selection Notes

Select this part when a robust NTC thermistor is required for high-current inrush protection. The 3 Ohm resistance value provides effective current limiting while maintaining low steady-state voltage drop. Consider the 18 mm body size for adequate heat dissipation in confined spaces compared to smaller variants.

Inrush Current Limiters (ICL) Part Context

This component belongs to the SP series of NTC thermistors manufactured by YAGEO. These devices are specifically engineered for surge current suppression in various industrial and consumer electronics applications. The SP series offers reliable performance across a broad temperature spectrum.

Inrush Current Limiters (ICL) Replacement Considerations

Check for direct substitutes within the same SP series or equivalent NTC thermistors from other manufacturers. Verify that any replacement maintains the 3 Ohm resistance, 7 A current rating, and compatible physical dimensions for PCB integration.
