N13SP025M

Inrush Current Limiters (ICL) Overview

The N13SP025M is a Negative Temperature Coefficient (NTC) thermistor from the YAGEO SP series, designed as an inrush current limiter. It features a nominal resistance of 25 Ohms with a tolerance of ±20%. The component has a radial lead configuration and a cylindrical package with a diameter of 13 mm (0.512 inches). It supports a maximum operating temperature of +200 °C and a minimum of -40 °C. The device is rated for a steady-state current of 3 A and includes a lead spacing of 7.5 mm.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective limitation of high inrush currents during power-up sequences
• Utilizes negative temperature coefficient characteristics to reduce resistance as temperature rises
• Features robust construction suitable for PCB mounting applications

Inrush Current Limiters (ICL) Applications

• Power supply input stages for inrush current protection
• Motor drive circuits requiring startup current limiting
• General electronic equipment power inputs

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix requirements for your application, as variants such as N13SP025M-F may exist with different packaging or compliance attributes. Confirm that the 3 A current rating and 25 Ohm resistance align with your circuit's thermal and electrical design constraints. Ensure the 7.5 mm lead spacing fits your printed circuit board layout. Check for RoHS compliance status if required by your manufacturing standards.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 25 Ohm initial resistance is required to limit peak charging currents. The 3 A rating determines the maximum continuous load capacity after the thermistor heats up. Consider the physical dimensions of the 13 mm diameter body for board space allocation. Evaluate the thermal environment to ensure the +200 °C maximum operating temperature is not exceeded under worst-case conditions.

Inrush Current Limiters (ICL) Part Context

This part belongs to the YAGEO SP series of NTC thermistors, which are specialized for inrush current limiting rather than temperature sensing. Unlike general-purpose resistors, these components rely on their changing resistance properties to protect downstream circuitry from high initial surge currents common in capacitive loads.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 25 Ohm nominal resistance, 3 A current rating, and 13 mm diameter. Verify that alternative manufacturers offer compatible lead spacing and thermal characteristics. Cross-reference datasheets to ensure equivalent energy absorption capabilities and response times.
