SL320R530

Overview

The SL320R530 is a radial leaded inrush current limiter from the Vishay Ametherm SL32 series. It features a nominal resistance of 0.5 ohms with a tolerance of ±20%. The component is rated for a steady-state current of 30 A and has a physical diameter of 31 mm. Designed for PCB mounting, it utilizes a radial termination style suitable for through-hole applications.

Feature Summary

• Provides effective limitation of high inrush currents during power-up sequences to protect downstream circuitry.
• Features a robust ceramic composition designed to withstand repeated thermal cycling without degradation.
• Offers stable electrical characteristics across a wide operating temperature range for reliable industrial performance.

Applications

• Power supply input stages
• Industrial automation control systems
• Embedded system power management

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct resistance and current ratings. Confirm that the radial lead spacing matches the target PCB footprint. Check RoHS compliance status if required by project specifications. Ensure the 30 A rating aligns with the application's continuous load requirements.

Selection Notes

Select this component when a low-resistance path is needed for high-current applications requiring moderate inrush limiting. The 31 mm diameter provides sufficient thermal mass for 30 A operation. Consider the SL32 series for general-purpose industrial electronics where standard radial mounting is preferred over axial or surface-mount alternatives.
