N13SP018L

Inrush Current Limiters (ICL) Overview

The YAGEO N13SP018L is a Negative Temperature Coefficient (NTC) thermistor designed for inrush current limiting applications. It features an initial resistance of 18 Ohms with a tolerance of ±15%. The component has a power rating of 3 W and a current rating of 3 A. It utilizes a radial leaded package with a diameter of 13 mm, width of 6 mm, and lead spacing of 7.5 mm. The operating temperature range spans from -40°C to +200°C.

Inrush Current Limiters (ICL) Feature Summary

• Effectively restrains electrical 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 components

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix designation when ordering, as variants such as N13SP018L-F exist within the product line. Confirm that the required resistance value of 18 Ohms and current rating of 3 A align with the circuit design requirements. Ensure the radial PCB mount style fits the target assembly layout. Check official documentation for any regional distribution restrictions or obsolescence notices prior to finalizing procurement plans.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required 18 Ohm initial resistance and 3 A steady-state current capacity. The 13 mm diameter and 7.5 mm lead spacing must match the printed circuit board footprint constraints. Verify that the maximum operating temperature of 200°C exceeds the expected thermal environment. Consider the 3 W power rating to ensure adequate thermal dissipation capabilities during high-energy transient events without exceeding safe operating limits.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SP series of NTC thermistors manufactured by YAGEO. These components are specialized for managing transient currents rather than precision temperature sensing. The radial leaded construction facilitates through-hole mounting on standard PCBs. The series is engineered to balance effective surge suppression with minimal energy dissipation once the circuit reaches normal operation.
