SL10 50002-A

Inrush Current Limiters (ICL) Overview

The SL10 50002-A is an NTC thermistor inrush current limiter from the Vishay Ametherm SL10 series. It features a nominal resistance of 50 ohms at 25°C with a tolerance of ±25%. The component supports a maximum steady-state current of up to 2.00 A at 65°C and can withstand a recommended energy rating of 18 Joules. Designed for radial leaded mounting, it utilizes a ceramic body construction suitable for PCB integration.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes negative temperature coefficient (NTC) technology to provide high initial resistance that decreases as temperature rises during operation.
• Capable of absorbing significant inrush energy, rated for 18 Joules, to protect downstream components during power-up.
• Features a robust ceramic element housed within a protective coating to ensure mechanical stability and environmental resistance.

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'A' against official Vishay documentation to confirm if it denotes a specific tape-and-reel variant or standard bulk packaging, as generic listings may not distinguish this detail. Confirm RoHS compliance status directly with the manufacturer's latest datasheet revision. Ensure the supplier provides traceability certificates matching the exact part number designation.

Inrush Current Limiters (ICL) Selection Notes

Select this component when circuit design requires a 50-ohm initial impedance to limit startup current peaks. The 18-Joule energy rating dictates suitability for moderate-power applications where thermal mass must absorb transient loads. Verify that the 2.00 A steady-state current capacity aligns with the continuous operating requirements of the target load without exceeding thermal limits.

Inrush Current Limiters (ICL) Part Context

This device belongs to the SL10 series of inrush current limiters, characterized by a 10mm diameter form factor. The series is engineered for general-purpose electronic equipment requiring reliable startup protection. The SL10 50002-A represents a specific resistance value within this family, offering a balance between limiting capability and low steady-state power loss.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with Vishay Ametherm SL10 series parts sharing identical 50-ohm resistance and 18-Joule ratings. Verify mechanical dimensions and lead spacing compatibility before substitution. Ensure equivalent thermal characteristics and voltage ratings are maintained in the new component selection.
