SL15 12102-A

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL1512102 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% at 25°C. The component has a steady-state maximum current rating of 2 A and operates within voltage ratings of 115 VAC and 230 VAC. Physical dimensions include a diameter of 15 mm, a width of 6 mm, and a lead spacing of 7.8 mm. The leads are radial with a diameter of 1 mm, suitable for PCB mounting.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes NTC thermistor technology to suppress high initial charging currents in electronic circuits.
• Provides UL certification for safety compliance in power supply applications.
• Features radial kinked leads optimized for through-hole PCB mounting.

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix designation when ordering, as standard datasheets reference SL1512102 without an 'A' suffix. Confirm that the required lead configuration matches the kinked radial style documented for this series. Ensure the 2 A steady-state current rating aligns with the target circuit's operational requirements before finalizing procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component for applications requiring moderate inrush suppression with a 120 Ohm cold resistance. The 15 mm diameter provides sufficient thermal mass for 2 A continuous operation. Consider the 7.8 mm lead pitch for PCB layout compatibility. Evaluate thermal dissipation needs against the ambient temperature conditions of the final assembly.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL15 series of inrush current limiters from Vishay Ametherm. The series offers various resistance and current combinations housed in 15 mm diameter packages. These components are engineered to protect sensitive downstream electronics from damage during power-up events by limiting the initial surge current flowing into capacitive loads.

Inrush Current Limiters (ICL) Replacement Considerations

Public documentation confirms the SL1512102B as a substitute part number within the same series. Verify electrical parameters and physical dimensions match before replacement.
