N20SP004L-F

Inrush Current Limiters (ICL) Overview

The N20SP004L-F is an NTC thermistor inrush current limiter manufactured by YAGEO. It features a nominal resistance of 4 ohms with a tolerance of ±15%. The component has a current rating of 8 A and a power rating of 6.5 W. It operates within a temperature range of -40°C to +200°C. Physical dimensions include a diameter of 20 mm, a width of 7.5 mm, and a lead spacing of 7.5 mm. The device utilizes radial leads for PCB mounting.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter to protect electronic circuits during power-up.
• Utilizes negative temperature coefficient characteristics to reduce steady-state resistance after initial surge.
• Designed for through-hole PCB mounting applications.

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'F' against official YAGEO documentation to confirm if it denotes a specific packaging or tape-and-reel configuration distinct from the base part number. Ensure the selected variant matches the required lead spacing and physical footprint for the target PCB layout. Cross-reference the electrical ratings with the system's peak inrush requirements to prevent component failure.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required nominal resistance of 4 ohms and the 8 A current handling capability. Confirm that the 20 mm diameter fits the available board space and that the radial lead configuration aligns with the assembly process. Validate thermal management requirements given the 6.5 W power rating and operating temperature limits.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SP series of NTC thermistors designed specifically for inrush current limiting. These components are engineered to withstand high initial current surges while providing effective circuit protection. The radial package style facilitates easy integration into standard through-hole manufacturing processes.
