SL0822002

Inrush Current Limiters (ICL) Overview

The SL0822002 is a negative temperature coefficient (NTC) inrush current limiter manufactured by Vishay Ametherm. Designed for PCB mounting with radial leads, this component features a nominal resistance of 22 Ohms at 25°C with a tolerance of ±20%. It supports a maximum steady-state current of 2.0 A and has a recommended energy rating of 8.0 Joules. The device withstands an actual failure point of instantaneous energy up to 16.0 Joules. Physical dimensions include a body diameter of 8.50 mm (0.335 inches). Key thermal specifications include a dissipation constant of 9.0 mW/°C and a maximum allowable power consumption resulting in a body temperature of 147°C at full current rating.

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific lead configuration required for your assembly process. The manufacturer distinguishes between straight leads and inside kinked leads. To order the inside kinked lead variant, append the suffix '-A' to the part number (e.g., SL0822002-A). Outside kinked leads are not available for this series. Confirm RoHS compliance status through official documentation prior to final procurement decisions.

Inrush Current Limiters (ICL) Selection Notes

Select the SL0822002 when circuit design requires a 22 Ohm cold resistance and a 2.0 A continuous current handling capability. Ensure the application's peak inrush energy does not exceed the 8.0 Joule recommended rating to maintain long-term reliability. Consider the 8.50 mm body diameter for spatial constraints on the printed circuit board. This component is appropriate for systems requiring UL-certified inrush protection with standard radial lead termination.
