SL0812101T

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL0812101T is a Negative Temperature Coefficient (NTC) thermistor designed for inrush current limiting. It features a nominal resistance of 120 Ohms with a tolerance of ±25%. The device supports a maximum steady-state current of 1 A and has a body diameter of 0.315 inches (8.00 mm). Key electrical characteristics include a dissipation constant of 9 mW/°C and a body temperature of 95°C at maximum current. Resistance values are specified as 1.80 Ω at 50% max current.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limitation through NTC thermistor technology
• Supports high steady-state current handling capabilities
• Features compact cylindrical form factor for easy integration

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Motor drive circuits
• Transformer protection systems

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'T' against official Vishay documentation to confirm tape-and-reel packaging requirements. Ensure the 120 Ohm nominal resistance and 1 A current rating align with circuit design specifications. Confirm that the 8.00 mm body size fits within the mechanical constraints of the target assembly. Cross-reference the AEC-Q101 qualification status if automotive compliance is required, though this is typically associated with semiconductor products rather than passive thermistors.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a robust inrush limiter with a 120 Ohm initial resistance is needed. The 1 A current rating suits moderate power applications. Consider the 9 mW/°C dissipation constant for thermal management calculations. The 8.00 mm diameter allows for standard mounting methods. Evaluate the 95°C body temperature limit to ensure safe operation under continuous load conditions without overheating the surrounding components.

Inrush Current Limiters (ICL) Part Context

The SL08 series represents Vishay Ametherm's line of leaded NTC thermistors optimized for inrush current control. These components utilize barium titanate-based ceramic materials to provide non-linear resistance characteristics. The SL0812101T variant specifically targets applications requiring reliable startup protection for capacitive loads or transformer primaries in consumer and industrial electronics.
