AMPHENOL ADVANCED SENSORS CL40 Inrush Current Limiter

The CL-40 is a two-pin NTC thermistor designed as an inrush current limiter. It features a small form factor, offering advantages over larger passive components and solid-state devices for inrush current suppression. The disc thermistor has uninsulated lead wires and effectively reduces current surges caused by large filter capacitors in switch-mode power supplies. Its primary function is to prevent damage to components in series with the input of DC/DC converters by limiting maximum surge currents. The thermistor is suitable for PCB mounting, with low steady-state resistance to minimize power loss. It boasts excellent mechanical strength, a wide operating temperature range from -50°C to 175°C, and high capacitance ratings. The device is ideal for applications in consumer electronics, power management, lighting, and motor drive and control systems.
