CL22250100

Inrush Current Limiters (ICL) Overview

The CL22250100 is a PTC inrush current limiter from the MegaSurge series, manufactured by Vishay Ametherm. It features a nominal resistance of 25 Ohms with a tolerance of ±25% at 25°C. The component has a disc diameter of 22mm and is rated for a maximum steady-state current of 3.5A. It utilizes NTC thermistor technology to limit initial surge currents while maintaining low power dissipation during normal operation.

Inrush Current Limiters (ICL) Feature Summary

• High voltage rating allows withstandment of hundreds of maximum inrush current hits without degradation
• PTC construction provides effective inrush current limiting for transformer protection
• Low steady-state power dissipation ensures efficient operation after initial surge

Inrush Current Limiters (ICL) Applications

• Transformer inrush current protection
• Power supply input stage surge suppression
• Electronic equipment requiring high reliability against repeated surge events

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for the CL22250100 to confirm thermal characteristics and mounting requirements. Ensure that the application circuit design accounts for the 25 Ohm nominal resistance and 3.5A steady-state current limits. Cross-reference with official Vishay documentation to validate performance under expected operating temperatures and surge conditions.

Inrush Current Limiters (ICL) Selection Notes

Select this component when high-cycle durability against inrush currents is required. The 22mm disc size supports significant energy absorption. Consider the 25 Ohm resistance value for appropriate current limiting in the target circuit. Verify compatibility with UL or CSA certification requirements if applicable to the end product.
