CL-170

Inrush Current Limiters (ICL) Overview

The CL-170 is a Negative Temperature Coefficient (NTC) inrush current limiter manufactured by Amphenol Advanced Sensors. It features a disc thermistor design with uninsulated lead wires, providing excellent mechanical strength. The component has a nominal resistance of 16 Ohms at 25°C with a tolerance of ±25%. It supports a steady-state current of 2.7 A and has a physical diameter of 13.97 mm (0.550 inches). These devices function as power resistors to control inrush current in switching power supplies, fluorescent lamps, and inverters.

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version from Amphenol Advanced Sensors or authorized distributors to confirm exact electrical tolerances and thermal characteristics. Ensure the selected component matches the required steady-state current and nominal resistance specifications for the target circuit application before finalizing procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on its 16 Ohm nominal resistance and 2.7 A current rating. Consider the 13.97 mm diameter for spatial constraints. Verify compatibility with the specific inrush current requirements of the target equipment, such as power supplies or lighting systems, to ensure effective protection against surge currents.

Inrush Current Limiters (ICL) Part Context

The CL-170 belongs to the CL series of NTC inrush current limiters produced by Amphenol Advanced Sensors (Thermometrics). This series is designed to protect electronic circuits from high initial charging currents. The component utilizes NTC thermistor technology to provide high resistance at startup, which decreases as temperature rises during operation.

Inrush Current Limiters (ICL) Replacement Considerations

Consult official Amphenol documentation for confirmed substitute part numbers within the CL series or equivalent NTC limiters with matching 16 Ohm resistance and 2.7 A current ratings.
