CL-180A

Inrush Current Limiters (ICL) Overview

The CL-180A is a negative temperature coefficient (NTC) inrush current limiter manufactured by Amphenol Advanced Sensors. It features a resistance of 16 Ohms at 25°C with a tolerance of ±25%. The device has a continuous current rating of 1.7 A and an AC voltage rating between 120 V and 240 V. The physical dimensions are 13.97 mm (0.550 inches). The cold resistance is specified as 490 mOhms.

Inrush Current Limiters (ICL) Feature Summary

• Designed to limit high inrush currents during power-up sequences
• Utilizes NTC ceramic material for self-regulating thermal response
• Constructed with kinked leads for secure PCB mounting

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer protection circuits
• Capacitive load switching applications

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for the CL-180A, as lead times may vary based on manufacturing schedules. Confirm that the 1.7 A current rating and 16 Ohm resistance align with the target circuit's peak inrush requirements. Ensure the kinked lead style matches the intended PCB footprint and mechanical constraints.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a compact, through-hole NTC limiter is required for low-current AC or DC applications. The 16 Ohm initial resistance provides moderate surge suppression suitable for small loads. Consider the 1.7 A steady-state limit to ensure the device does not overheat during normal operation. The kinked lead design aids in mechanical stability during wave soldering.

Inrush Current Limiters (ICL) Part Context

The CL series represents Amphenol Thermometrics' standard line of inrush current limiters. These components are widely used in consumer electronics and industrial control systems where cost-effective surge protection is needed. The CL-180A specifically targets applications requiring lower current handling compared to larger diameter limiters.
