SL2216005

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL2216005 is a radial leaded inrush current limiter from the SL22 series. It features a 22mm diameter body with a nominal resistance of 16 ohms at 25°C and a tolerance of ±20%. The component supports a maximum steady-state current of 5 amps and has a recommended maximum energy rating of 100 Joules. Designed for PCB mounting, it utilizes radial leads for through-hole integration into power supply circuits to limit initial surge currents.

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct resistance and current ratings. Confirm package type and lead configuration match the target PCB footprint. Check RoHS compliance status if required by project specifications. Ensure the maximum energy rating aligns with the application's capacitive load requirements.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required steady-state current capacity and initial resistance value. Evaluate the maximum energy rating against the system's stored charge to prevent device failure. Consider the physical dimensions for adequate spacing on the printed circuit board. Verify compatibility with the operating voltage range and ambient temperature conditions.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL22 series of inrush current limiters manufactured by Vishay Ametherm. The series offers various resistance values and current ratings within a consistent 22mm form factor.
