N20SP020M

Inrush Current Limiters (ICL) Overview

The N20SP020M is a Negative Temperature Coefficient (NTC) thermistor manufactured by YAGEO, designed for inrush current limiting applications. It features a radial leaded package with a disc diameter of 20 mm and a width of 7.5 mm. The component has a nominal resistance of 20 Ohms with a tolerance of ±20%. It supports a continuous current rating of 6 A and a power rating of 2 W. The operating temperature range spans from -40°C to +170°C, with a lead spacing of 7.5 mm.

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 input stages
• Over-current protection in industrial control systems

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix requirements against the official YAGEO datasheet, as ordering codes may dictate packaging or compliance variations. Confirm that the 20 Ohm resistance and 6 A current rating align with the target circuit design parameters before procurement. Ensure the radial PCB mount style matches the intended assembly process.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 20 mm diameter NTC thermistor is required for handling high inrush currents up to 6 A. The 20 Ohm initial resistance is suitable for moderate voltage inputs where significant current limiting is needed at turn-on. Consider the 7.5 mm lead spacing for compatible PCB footprint design and verify thermal management capabilities within the -40°C to +170°C operational window.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SP series of NTC thermistors from YAGEO, specialized for inrush current limiting. It shares the radial leaded form factor common to this family but is distinguished by its 20 mm diameter and 20 Ohm resistance value. It serves as a passive protection element in power electronics, contrasting with higher-capacity variants like the N25SP001M-F or lower-resistance options.

Inrush Current Limiters (ICL) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative NTC thermistors based on matching resistance, current rating, and physical dimensions.
