N25SP1R5L-F

Inrush Current Limiters (ICL) Overview

The N25SP1R5L-F is a Negative Temperature Coefficient (NTC) thermistor manufactured by YAGEO, designed for inrush current limiting applications. It features a nominal resistance of 1.5 Ohms with a tolerance of ±15%. The component has a current rating of 15 A and a power rating of 6.5 W. It utilizes a radial leaded package with a 7.5 mm lead spacing and a bulk packaging format. The device operates within a temperature range of -40°C to +200°C and has a diameter of 25 mm.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limitation during power-up sequences
• Features negative temperature coefficient characteristics for self-regulating resistance
• Supports high current handling capabilities up to 15 A

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Motor drive circuits
• Transformer protection systems

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix and tolerance requirements against the design specification before ordering. Confirm that the thermal management strategy accounts for the steady-state heat dissipation at 6.5 W. Ensure the PCB layout accommodates the 25 mm diameter and 7.5 mm lead spacing. Check for RoHS compliance documentation if required by the end product regulations.

Inrush Current Limiters (ICL) Selection Notes

Select this component when the circuit requires a 1.5 Ohm initial resistance to limit peak inrush currents. The 15 A rating must exceed the maximum expected surge current of the application. Consider the operating temperature range limits and the physical size constraints of the PCB assembly. Verify compatibility with the mounting style and lead configuration.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SP series of NTC thermistors from YAGEO. These components are specifically engineered for inrush current limiting rather than temperature sensing. The series offers various resistance values and current ratings to suit different power levels. The radial leaded format allows for through-hole mounting on printed circuit boards.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other YAGEO NTC thermistors with similar resistance and current ratings, such as the N25SP005L-F or N25SP001M-F, provided their electrical parameters match the circuit requirements. Cross-brand replacements require careful verification of B-constant, resistance tolerance, and physical dimensions.
