Inrush Current Limiters (ICL) Procurement Notes

Verify that the specific order matches the CL-150 designation rather than similar variants like CL-150A or CL-150B, which may differ in packaging or lead configuration. Confirm that the required current rating of 4.7 A and resistance value of 5 Ohms align with the design specifications. Ensure compatibility with the intended voltage ratings of 115 VAC or 230 VAC. Check for RoHS compliance requirements if applicable to the final assembly standards.

Inrush Current Limiters (ICL) Selection Notes

Select this component when designing circuits requiring passive inrush current limiting for AC-powered loads. The 5 Ohm initial resistance effectively restricts peak charging currents for capacitive inputs. The 4.7 A steady-state rating determines the maximum continuous load capacity after the thermistor heats up. Consider the physical size of 13.97 mm diameter for board space allocation. The straight lead style facilitates through-hole mounting on printed circuit boards.

Inrush Current Limiters (ICL) Part Context

The CL-150 belongs to the CL series of inrush current limiters produced by Amphenol Advanced Sensors under the Thermometrics brand. This series is specifically engineered for protecting electronic components against high initial current surges. The device relies on the negative temperature coefficient property of ceramic materials to reduce resistance as it warms up during operation.
