SL1512102

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL1512102 is a radial leaded Negative Temperature Coefficient (NTC) thermistor designed as an inrush current limiter. It features a nominal resistance of 120 Ohms with a tolerance of ±25% at 25°C. The component supports a maximum steady-state current of 2 A and has a body diameter of 15 mm. It is UL approved and RoHS3 compliant, suitable for protecting circuits against high initial surge currents.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes NTC thermistor technology to provide high initial resistance that decreases as temperature rises, effectively limiting inrush current.
• Radial leaded construction facilitates through-hole PCB mounting for robust mechanical connection.
• Certified by UL for safety compliance in electronic equipment applications.

Inrush Current Limiters (ICL) Applications

• Protection of power supplies against high inrush currents during startup
• Transformer inrush current limitation in AC/DC conversion circuits
• Surge protection in general electronic equipment power inputs

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix matches the required resistance tolerance and current rating. Confirm package type is radial leaded. Check for RoHS3 compliance status if restricted substances are a concern. Ensure the supplier provides valid UL certification documentation for the component series.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required steady-state current capacity of 2 A and the specific cold resistance value of 120 Ohms. Consider the thermal dissipation factor and maximum recommended energy absorption capabilities when designing the circuit protection strategy. Verify physical dimensions fit the available PCB space.
