CL-150AB

Inrush Current Limiters (ICL) Overview

The CL-150AB is an NTC thermistor inrush current limiter from the CL series by Amphenol Advanced Sensors. It features a nominal resistance of 5 Ohms with a tolerance of ±25% at 25°C. The device supports a maximum steady-state current of 4.7 A and operates within voltage ratings of 115 VAC or 230 VAC. Physical dimensions include a diameter of 13.97 mm and a width of 4.57 mm, with straight leads for PCB mounting. The operating temperature range spans from -50°C to +175°C.

Inrush Current Limiters (ICL) Feature Summary

• Designed to limit inrush current in switching power supplies and motor circuits
• Utilizes negative temperature coefficient (NTC) thermistor technology for rapid resistance drop after startup
• Constructed for direct PCB mounting with straight lead configuration

Inrush Current Limiters (ICL) Applications

• Switching power supply input stages
• Fluorescent lamp ballast protection
• Inverter circuit protection
• Motor drive input filtering

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix AB against official datasheets to confirm lead type and packaging variations. Ensure compatibility with PCB footprint dimensions of 13.97 mm diameter and 8.33 mm lead spacing. Confirm RoHS compliance status and UL certification requirements for end-product safety approvals prior to final procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component when designing circuits requiring robust inrush current suppression for AC mains inputs up to 230 VAC. The 5 Ohm initial resistance effectively limits peak charging currents for capacitive loads. Consider the 4.7 A steady-state rating to ensure thermal stability during continuous operation without excessive self-heating.

Inrush Current Limiters (ICL) Part Context

The CL-150AB belongs to the CL series of inrush current limiters manufactured by Amphenol Advanced Sensors under the Thermometrics brand. This series is widely recognized for providing reliable protection against high surge currents in electronic power conversion systems, ensuring component longevity and system stability.

Inrush Current Limiters (ICL) Replacement Considerations

The CL-150A is a documented substitute part number within the same series offering identical electrical specifications including 5 Ohm resistance and 4.7 A current rating. Verify mechanical lead spacing and package dimensions before substitution.
