N20SP001L

Inrush Current Limiters (ICL) Overview

The YAGEO N20SP001L is a Negative Temperature Coefficient (NTC) thermistor designed as an inrush current limiter. It features a nominal resistance of 1 Ohm at 25°C with a tolerance of ±15%. The component supports a maximum steady-state current of 10 A and has a power rating of 6.5 W. It operates within a temperature range of -40°C to +200°C. The unit utilizes a radial leaded package with a diameter of 20.00 mm and a lead spacing of 5 mm.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter to protect electronic circuits from high initial surge currents during power-up.
• Utilizes negative temperature coefficient characteristics to provide low resistance at room temperature and high resistance when heated by current flow.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Motor drive protection
• Transformer primary side protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the current manufacturing status, as this specific part number may be discontinued or superseded by newer revisions. Confirm that the 1 Ohm resistance and 10 A current ratings align with the target circuit's surge requirements. Ensure the radial PCB mounting style fits the mechanical design constraints.

Inrush Current Limiters (ICL) Selection Notes

Select this component for applications requiring robust inrush current suppression in high-power environments. The 20 mm diameter provides sufficient thermal mass for handling significant energy dissipation. Verify compatibility with the operating temperature range up to 200°C for high-heat scenarios.

Inrush Current Limiters (ICL) Part Context

This component belongs to the SP series of NTC thermistors manufactured by YAGEO Corporation. These devices are specialized sensors and transducers used primarily for circuit protection rather than precise temperature measurement. The series is engineered for durability in demanding industrial and consumer electronics applications.

Inrush Current Limiters (ICL) Replacement Considerations
