CL06251120

Inrush Current Limiters (ICL) Overview

The CL06251120 is a Positive Temperature Coefficient (PTC) thermistor manufactured by Vishay Ametherm, functioning as an inrush current limiter (ICL). It features a nominal resistance of 250 Ohms with a tolerance of ±20%. The component has a cylindrical body diameter of 6.5 mm and operates within a temperature range of -55°C to +70°C. It utilizes radial termination for PCB mounting and carries a current rating of 28 mA.

Inrush Current Limiters (ICL) Feature Summary

• Provides automatic inrush current limiting through positive temperature coefficient characteristics
• Radial leaded construction designed for printed circuit board mounting
• Compact cylindrical form factor suitable for space-constrained electronic assemblies

Inrush Current Limiters (ICL) Applications

• Inrush current protection in power supply input stages
• Overcurrent protection circuits for low-current electronic devices
• Temperature compensation applications requiring PTC response

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct resistance and tolerance specifications. Confirm that the radial lead spacing matches the target PCB footprint design. Check current availability status as distribution may be limited or restricted in certain regions. Ensure compliance with RoHS3 standards if required by the end product regulations.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 250 Ohm nominal resistance at room temperature is required for inrush limiting. The 28 mA current rating dictates suitability for low-power applications only. Verify that the operating environment remains within the specified -55°C to +70°C range. Consider the 6.5 mm diameter for mechanical clearance constraints on the assembly.

Inrush Current Limiters (ICL) Part Context

This part belongs to the CL series of PTC thermistors from Vishay Ametherm. These components are distinct from standard NTC thermistors used for temperature sensing, as they are engineered specifically for current limiting functions. The series offers various resistance values and package sizes to accommodate different circuit requirements.

Inrush Current Limiters (ICL) Replacement Considerations

No public confirmed substitute part numbers are available in the provided data. Cross-referencing requires matching the 250 Ohm resistance, 28 mA rating, and 6.5 mm diameter dimensions precisely.
