SL1522102

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL1522102 is a radial leaded inrush current limiter with a nominal resistance of 220 Ohms and a steady-state current rating of 2 A. Designed for PCB mounting, it features a 16 mm diameter body and 7.8 mm lead spacing. The component supports voltage ratings of 115 VAC and 230 VAC, with a tolerance of ±25%. It operates within a temperature range defined by its thermal characteristics and includes UL approval.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective limitation of high inrush currents during power-up sequences to protect downstream circuitry.
• Features negative temperature coefficient behavior where resistance decreases as the device heats up during operation.
• Includes UL certification for compliance with safety standards in electrical equipment applications.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary circuits
• Capacitor charging protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against official Vishay documentation to ensure correct tolerance and packaging configuration. Confirm that the radial lead pitch matches the target PCB footprint design. Check RoHS compliance status directly from the manufacturer datasheet before finalizing procurement specifications.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required steady-state current of 2 A and initial resistance value of 220 Ohms. Ensure the physical dimensions fit the available board space. Consider the maximum recommended energy rating when designing for capacitive loads to prevent device failure during switching events.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL15 series of inrush current limiters manufactured by Vishay Ametherm. The series offers various resistance and current combinations to suit different power levels. These components are widely used in consumer electronics and industrial power supplies requiring reliable startup protection.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other Vishay Ametherm parts within the SL15 family with matching 2 A current ratings. Verify equivalent resistance values and physical dimensions before swapping. Cross-reference with competitor NTC thermistors only if electrical parameters and package size are identical.
