N20SP2R5L

Inrush Current Limiters (ICL) Overview

The YAGEO N20SP2R5L is an NTC thermistor designed as an inrush current limiter. It features a nominal resistance of 2.5 Ohms with a tolerance of ±15%. The component has a current rating of 8 A and operates with a lead spacing of 7.5 mm. Its physical dimensions are 20.00 mm (0.787 inches). This device is classified under the SP series and utilizes NTC technology for surface mount or PCB mounting applications.

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 (NTC) technology where resistance decreases as temperature increases.
• Designed for robust performance with an 8 A current rating capability.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Motor drive protection circuits
• Transformer inrush limiting

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix requirements, such as -F, against the target application datasheet to ensure correct packaging and terminal configuration. Confirm that the 2.5 Ohm nominal resistance and 8 A rating align with the circuit's surge energy specifications. Ensure compatibility with the required lead spacing and mounting style for the printed circuit board layout.

Inrush Current Limiters (ICL) Selection Notes

Select this component when the circuit requires suppression of high inrush currents at startup. The 2.5 Ohm resistance value must be appropriate for the steady-state operating conditions without causing excessive voltage drop. Consider the thermal management requirements, as the resistance changes significantly with temperature during operation.

Inrush Current Limiters (ICL) Part Context

This part belongs to YAGEO's SP series of NTC thermistors. These components are specifically engineered for inrush current limiting applications rather than general-purpose sensing. The series offers standardized dimensions and electrical characteristics suitable for common industrial and consumer electronics power inputs.
