N13SP1R5M-F

Inrush Current Limiters (ICL) Overview

The YAGEO N13SP1R5M-F is a Negative Temperature Coefficient (NTC) thermistor belonging to the SP series, designed for inrush current limiting applications. It features a radial leaded package with a diameter of 16 mm and a width of 6 mm. The component has a nominal resistance of 1.5 Ohms at standard conditions, with a tolerance of ±20%. It supports a continuous power rating of 3 W and a maximum current rating of 7 A. The device operates within a temperature range of -40°C to +200°C and utilizes a 7.5 mm lead spacing for PCB mounting.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limitation during power-up sequences
• Features robust thermal stability with a wide operating temperature range up to 200°C
• Utilizes a radial through-hole package suitable for direct PCB integration

Inrush Current Limiters (ICL) Applications

• Power supply input stages for inrush current protection
• Transformer primary side protection circuits
• Motor drive input filtering and surge suppression

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific manufacturing status as some distributors list this part as obsolete or end-of-life. Confirm availability through official YAGEO channels or authorized partners rather than third-party stock claims. Ensure the order suffix matches the required packaging format if specified in the final datasheet. Cross-reference the exact resistance value and tolerance against the latest product specification sheet before procurement to avoid substitution errors.

Inrush Current Limiters (ICL) Selection Notes

Select this component when high peak current handling is required alongside low steady-state resistance. The 7 A current rating and 3 W power dissipation make it suitable for medium-power AC/DC converters. Compare against similar SP series parts like N13SP008M-F for higher resistance needs. Ensure the PCB layout accommodates the 16 mm diameter and 7.5 mm lead spacing. Validate thermal management requirements given the self-heating characteristics under continuous load.

Inrush Current Limiters (ICL) Part Context

This part belongs to the YAGEO SP series of NTC thermistors, which are specialized for inrush current limiting rather than temperature sensing. Unlike general-purpose NTCs, these components are engineered to withstand high initial energy pulses while providing significant resistance drop once heated. The series offers various resistance values tailored for different voltage and current levels in power electronics.

Inrush Current Limiters (ICL) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Check for obsolescence notices from YAGEO. Potential alternatives may include other SP series variants with adjusted resistance values, but direct pin-for-pin functional equivalence requires verification against specific circuit parameters.
