CL-130A

Inrush Current Limiters (ICL) Overview

The CL-130A is an NTC inrush current limiter manufactured by Amphenol Advanced Sensors (Thermometrics). It features a nominal resistance of 50 Ohms at 25°C with a tolerance of ±25%. The device supports a maximum steady-state current of 1.6 A and exhibits a hot resistance of 750 mOhms at rated current. Physical dimensions include a length of 0.449 inches (11.40 mm) and kinked leads for through-hole mounting.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes negative temperature coefficient technology to limit initial surge currents
• Designed with kinked leads for secure through-hole PCB installation
• Provides thermal protection against high inrush currents during power-up

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary circuits
• Capacitive load protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific lead configuration, as the CL-130A specifies kinked leads which differ from standard straight-lead variants like the CL-130. Confirm that the 50 Ohm nominal resistance and 1.6 A current rating align with the target circuit's surge requirements. Ensure the package style matches the intended PCB footprint design.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 50 Ohm cold resistance is required for inrush limiting applications. The 1.6 A steady-state rating determines the maximum continuous operating current. Consider the physical size of 0.449 inches for board space constraints. Verify compatibility with the specific kinked lead form factor provided in this part number.

Inrush Current Limiters (ICL) Part Context

This component belongs to the Thermometrics line of NTC inrush current limiters. These devices are engineered to protect electronic circuits from damage caused by high initial charging currents. The product series offers various resistance values and current ratings to suit different power system designs.

Inrush Current Limiters (ICL) Replacement Considerations

The CL-130 is a related variant with identical electrical specifications but typically utilizes straight leads rather than kinked leads. When substituting, verify that the PCB footprint accommodates the lead shape difference.
