SL22 10007-B

Inrush Current Limiters (ICL) Overview

The SL2210007B is a negative temperature coefficient (NTC) thermistor inrush current limiter from the Vishay Ametherm SL22 series. It features a nominal resistance of 10 Ohms with a tolerance of ±20%. The component has a steady-state current rating of 7 A and operates at voltages up to 265 VAC. It utilizes a radial leaded package with a 22 mm diameter, designed for PCB mounting.

Inrush Current Limiters (ICL) Feature Summary

• Provides high energy absorption capacity to protect circuits during power-up
• Rapidly decreases resistance under steady-state conditions to minimize power loss
• Radial leaded construction facilitates through-hole PCB integration

Inrush Current Limiters (ICL) Applications

• Switching power supplies
• Uninterruptible power supplies (UPS)
• Industrial inverters and variable frequency drives

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix 'B' against the manufacturer's official datasheet to confirm if it denotes a custom specification or standard variant. Ensure the selected part matches the required voltage and current ratings for the target application circuit before finalizing procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 10 Ohm initial resistance and 7 A steady-state current are required for inrush protection. Consider the 22 mm form factor for available board space and verify that the 265 VAC rating aligns with the system's maximum operating voltage requirements.

Inrush Current Limiters (ICL) Part Context

This device belongs to the SL22 series of bigAMP inrush current limiters manufactured by Vishay Ametherm. These components are engineered to absorb high surge currents during equipment startup, preventing damage to downstream electronics while maintaining low steady-state power dissipation.

Inrush Current Limiters (ICL) Replacement Considerations

The SL2210007B may be functionally replaced by the SL2210007 or SL2210007A, which share identical core electrical specifications including 10 Ohms resistance and 7 A current rating within the same product family.
