SL084R003

Inrush Current Limiters (ICL) Overview

The SL084R003 is a radial leaded Negative Temperature Coefficient (NTC) thermistor designed as an inrush current limiter. It features a nominal resistance of 4 Ohms with a tolerance of ±20%. The component has a cylindrical body diameter of 8 mm and supports a steady-state current rating of 3 A. It operates within a temperature range of -40°C to +150°C and utilizes a radial termination style for through-hole PCB mounting.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of high inrush currents during power-up sequences
• Utilizes NTC material properties to reduce resistance as temperature increases
• Supports reliable operation across extended industrial temperature ranges

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• AC/DC converter circuits
• Electronic equipment protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for thermal characteristics and energy absorption ratings before integration. Confirm that the 8 mm package dimensions align with the target PCB footprint. Ensure the 3 A steady-state current rating exceeds the circuit's maximum operating current under all conditions. Cross-reference the 4 Ohm cold resistance value against system startup requirements.

Inrush Current Limiters (ICL) Selection Notes

Select this component when an 8 mm form factor is required for thermal management or mechanical clearance. The 4 Ohm resistance value is suitable for limiting initial charging currents in moderate power applications. Verify compatibility with the specific voltage class and frequency of the AC or DC source. Consider the thermal time constant relative to the duty cycle of the application.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Vishay Ametherm SL08 series, which comprises radial leaded NTC thermistors. The series offers various resistance values and diameters to accommodate different current handling requirements. These components are specifically engineered for inrush current limiting in consumer and industrial electronics.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other Vishay Ametherm parts from the SL08 series with matching 4 Ohm resistance and 8 mm diameter, such as SL084R003T if tape-and-reel packaging is preferred. Equivalent components from other manufacturers must match the 4 Ohm nominal resistance, 3 A current rating, and 8 mm physical dimensions.
