SL10 40002-A

Inrush Current Limiters (ICL) Overview

The SL1040002-A is a Negative Temperature Coefficient (NTC) thermistor designed as an inrush current limiter within the Vishay Ametherm SL10 series. This component features a nominal resistance of 40 Ohms with a tolerance of ±20% and a maximum steady-state current rating of 2.0 A at 65°C. It utilizes a radial leaded package with a 10 mm diameter body, suitable for through-hole mounting on printed circuit boards. The device operates effectively to suppress high initial charging currents during power-up sequences.

Inrush Current Limiters (ICL) Feature Summary

• Suppresses high inrush currents during power-up sequences
• Utilizes NTC material for automatic resistance reduction after startup
• Radial leaded construction for standard PCB mounting

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary circuits

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix designation against official documentation to confirm mechanical or electrical variations. Confirm availability status with authorized distributors as supply constraints may apply. Ensure the selected variant matches the required thermal and current ratings for the target application environment.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the 40 Ohm resistance value and 2.0 A current capacity requirements. Evaluate the 10 mm form factor for spatial constraints on the PCB layout. Consider the operating temperature range and thermal dissipation characteristics relative to the system's ambient conditions.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL10 series of inrush current limiters from Vishay Ametherm. The series offers various resistance values and physical sizes to accommodate different power levels.
