SL0850001A

Inrush Current Limiters (ICL) Overview

The SL0850001A is a radial lead inrush current limiter from the Vishay Ametherm SL08 series. It features a nominal resistance of 50 Ohms with a tolerance of ±15%. The component has a steady-state current rating of 1.1 A and is designed for PCB mounting. Physical dimensions include an 8 mm diameter (0.315 inches) body size. It utilizes axial leads for through-hole integration into electronic circuits requiring surge protection.

Inrush Current Limiters (ICL) Feature Summary

• Limits initial surge current during power-up to protect downstream components
• Provides automatic reset functionality after thermal cooling
• Radial leaded construction suitable for standard PCB assembly

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary side protection
• Capacitor charging circuit limiting

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'A' against the manufacturer datasheet to confirm exact electrical tolerances and physical specifications. Ensure compatibility with existing PCB footprint dimensions, particularly the 8 mm diameter constraint. Confirm that the 1.1 A steady-state current rating meets the operational requirements of the target application without exceeding thermal limits.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 50 Ohm resistance value is required to limit inrush current. The 1.1 A current rating defines the maximum continuous operating current. Consider the 8 mm package size for board space allocation. Verify that the radial lead configuration aligns with the assembly process and mechanical constraints of the final product design.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL08 series of ceramic inrush current limiters manufactured by Vishay Ametherm. These devices are thermistors designed to reduce high-frequency switching noise and limit inrush current in power supplies. The series offers various resistance and current ratings packaged in compact radial leaded forms for easy integration.

Inrush Current Limiters (ICL) Replacement Considerations

Consult the official Vishay Ametherm replacement guide for verified cross-reference part numbers. Do not substitute based solely on similar resistance values; ensure the steady-state current rating and physical dimensions match the original design requirements.
