SL320R230

Overview

The SL320R230 is a Vishay Ametherm inrush current limiter (ICL) from the SL32 series. It features a nominal resistance of 0.2 ohms with a tolerance of ±25%. The component has a steady-state current rating of 30 A and operates at voltages up to 265 VAC. Physical dimensions include a diameter of 31 mm (1.220 inches) and a pitch spacing of 3.22 mm. It utilizes radial leads for PCB mounting and carries UL approval.

Feature Summary

• Provides high-capacity surge suppression for demanding power applications
• Features robust thermal stability and low steady-state resistance
• Includes UL certification for safety compliance

Applications

• Power supply input stages
• Industrial control systems
• High-power consumer electronics

Procurement Notes

Verify the specific ordering suffix against official Vishay documentation to ensure correct resistance and current ratings. Confirm that the radial lead configuration matches your PCB footprint requirements. Check for any regional distribution restrictions or limited availability status before finalizing procurement plans.

Selection Notes

Select this component when high continuous current handling is required alongside effective surge protection. Ensure the operating voltage does not exceed the rated limit. Consider the physical size constraints due to the larger diameter compared to smaller series components.

Part Context

This part belongs to the SL32 series of inrush current limiters, designed for higher current applications than the SL03 or SL05 series. It serves as a thermistor-based solution to protect downstream circuitry from initial charging currents.

Replacement Considerations

Direct substitutes may include other Vishay Ametherm parts within the SL32 series with matching resistance and current ratings. Cross-reference datasheets for equivalent electrical characteristics and physical dimensions.
