SL1050002

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL1050002 is a negative temperature coefficient (NTC) inrush current limiter from the SL10 series. It features a nominal resistance of 50 ohms with a tolerance of ±25% at 25°C. The component has a maximum steady-state current rating of 1.60 A up to 65°C and a recommended energy rating defined by specific Joule limits. Its physical dimensions include a body diameter of 10 mm, with radial leads for through-hole mounting.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes NTC thermistor technology to provide high initial resistance that decreases as temperature rises during operation
• Designed specifically to limit inrush current in power supply circuits during startup phases
• Features a robust radial leaded package suitable for standard PCB mounting applications

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary circuit protection
• Capacitor charging current limiting

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for the SL1050002 to confirm the exact maximum recommended energy rating in Joules, as this parameter is critical for matching the surge capacity of the target application. Ensure the thermal environment does not exceed the maximum operating temperature limits specified in the official Vishay documentation to maintain reliability.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 50-ohm initial resistance is required to suppress startup surges. The 1.60 A steady-state current rating must accommodate the continuous load current without overheating. Consider the 10 mm body size for adequate spacing on the PCB layout to ensure proper heat dissipation and mechanical stability during assembly.
