SL3210015JU

Overview

The SL3210015JU is a radial leaded NTC thermistor from the Vishay Ametherm SL32 series, designed as an inrush current limiter. It features a nominal resistance of 10 Ohms with a tolerance of ±20%. The component supports a maximum steady-state current of 15 A at temperatures up to 65°C and has a diameter of 31 mm (1.220 inches). It utilizes a bulk packaging format.

Feature Summary

• Radial leaded construction for through-hole PCB mounting
• Negative temperature coefficient behavior for inrush current suppression
• UL approved for industrial safety compliance

Applications

• Power supply input stages
• Industrial control systems
• Consumer electronics power circuits

Procurement Notes

Verify the specific suffix 'JU' against official Vishay documentation to confirm if it denotes a unique tolerance or marking variation compared to the standard SL3210015. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when a 10 Ohm initial resistance and 15 A steady-state current rating are required for inrush protection. Consider the 31 mm diameter for physical space constraints and verify that the operating environment remains within the specified thermal limits for optimal performance.

Part Context

This part belongs to the SL32 series of inrush current limiters manufactured by Vishay / Ametherm. The series offers various resistance and current ratings tailored for different power applications, providing reliable surge protection for sensitive electronic components during startup phases.

Replacement Considerations

The SL3210015 is a direct functional equivalent with identical electrical parameters. Verify if the 'JU' suffix indicates any specific manufacturing lot or minor attribute differences requiring validation against the manufacturer's latest datasheet.
