Common mode chokes are devices designed to prevent electromagnetic interference from affecting system performance. They work by introducing a higher impedance path for electrical noise than the main signal path. The CM2722R450R-00 is a common mode choke that is typically used in power as well as signal lines. It is designed for applications requiring high common-mode impedance in a single inductor form factor.

The CM2722R450R-00 is designed for use in high current applications ranging from 0.1 to 5A. It has an inductance range of 24 to 45uH and an equivalent series resistance (ESR) value of 0.25 ohms (25mΩ max). The device has an operating temperature range of -40°C to +105°C. This makes it suitable for a wide range of applications, including power supplies, load switches, LED drivers, and automotive solutions.

The working principle of the CM2722R450R-00 is based on the concept of common mode inductance. This type of inductance is used to reduce the level of electromagnetic interference (EMI) that affects system performance. The device works by inducing a high impedance path for EMI radiation. This is done by winding two separate coils in opposite directions. The windings produce an inductance that opposes any current that is generated by EMI. The magnets used in this type of choke also help to reduce the EMI radiation, by providing a lower inductance for any current generated by the EMI.

The CM2722R450R-00 is designed to be used in applications such as low battery voltage surge suppression, EMI level control, and low frequency noise filtering. Its high common-mode impedance prevents EMI interference from affecting system performance. The device is capable of withstanding inrush currents up to 8.9 A and has a low current consumption of less than 1 mA. Its low profile form factor makes it suitable for high-density applications that require a small footprint.

The CM2722R450R-00 is a reliable and effective device for suppressing EMI radiation in applications that require high common-mode impedance. Its low-profile form factor enables it to be used in high-density applications, while its low ESR value ensures it can withstand inrush currents. The device’s high common-mode impedance prevents EMI interference from affecting system performance, making it a valuable addition to any design.
