N13SP010L

Inrush Current Limiters (ICL) Overview

The N13SP010L is a radial leaded Negative Temperature Coefficient (NTC) thermistor from the YAGEO SP series, designed as an inrush current limiter. It features a nominal resistance of 10 Ohms with a tolerance of ±15%. The component has a power rating of 2.5 W and a maximum steady-state current rating of 4 A. It operates within a temperature range of -40°C to +200°C. The ceramic element has a diameter of 13 mm and a width of 6 mm, with a standard lead spacing of 5 mm for PCB mounting.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limiting during power-up sequences
• Utilizes negative temperature coefficient characteristics for self-regulating resistance
• Features robust radial leads for secure through-hole PCB integration

Inrush Current Limiters (ICL) Applications

• Power supply input stages for surge protection
• Motor drive circuits for starting current control
• Transformer primary side inrush mitigation

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix requirements against official documentation, as variants like N13SP010L-F may exist with identical electrical parameters but different packaging or compliance markings. Confirm that the 13 mm diameter and 5 mm lead pitch match the target PCB footprint design. Ensure the thermal environment allows for adequate heat dissipation given the 2.5 W power rating. Cross-reference the manufacturer's latest datasheet to confirm availability status and any recent design changes.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 10 Ohm cold resistance is required to limit initial charging currents. The 4 A current rating suits moderate power applications. Consider the 13 mm size constraint for board layout. Compare against higher current alternatives if load demands exceed 4 A. Evaluate the operating temperature range to ensure stability up to 200°C. Check compatibility with soldering processes regarding thermal shock resistance.

Inrush Current Limiters (ICL) Part Context

This part belongs to the YAGEO SP series of NTC thermistors, specialized for inrush current limiting rather than temperature sensing. Unlike general-purpose resistors, these components exhibit significant resistance variation with temperature. They are distinct from MLCCs and thin-film resistors also offered by YAGEO. The series provides a cost-effective solution for protecting sensitive downstream electronics from high startup currents common in capacitive loads.
