N25SP018L-F

Inrush Current Limiters (ICL) Overview

The N25SP018L-F is a Negative Temperature Coefficient (NTC) thermistor from the YAGEO SP series, designed for inrush current limiting applications. It features an 18 Ohm resistance at standard conditions with a ±15% tolerance. The component supports a continuous current rating of 5.5 A and handles a power rating of 6.5 W. It utilizes radial leads with a 7.5 mm spacing for PCB mounting. The unit has a diameter of 29 mm and operates within a temperature range of -40°C to +200°C.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limitation through high initial resistance that decreases as temperature rises.
• Supports high thermal endurance with a maximum operating temperature of +200°C.
• Features robust mechanical construction suitable for direct PCB mounting via radial leads.

Inrush Current Limiters (ICL) Applications

• Inrush current limiting in AC/DC power supplies
• Protection circuits for electronic ballasts
• Motor starting circuits requiring surge suppression

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for the N25SP018L-F to confirm RoHS compliance status and detailed thermal characteristics. Ensure the selected distributor provides official documentation matching the manufacturer's specifications. Cross-reference the lead spacing and package dimensions against the target PCB layout to guarantee proper fitment during assembly.

Inrush Current Limiters (ICL) Selection Notes

Select this component when an 18 Ohm resistance value is required for inrush current control. The 5.5 A current rating and 6.5 W power handling define the operational limits for steady-state and transient conditions. Consider the 29 mm diameter and radial footprint for spatial constraints on the printed circuit board design.

Inrush Current Limiters (ICL) Part Context

This part belongs to the YAGEO SP series of NTC thermistors, which are specialized for inrush current limiting tasks. The series offers various resistance and current ratings to accommodate different power supply requirements. The N25SP018L-F specifically targets applications needing moderate surge protection with high thermal stability.

Inrush Current Limiters (ICL) Replacement Considerations
