Common Mode Chokes are used in a variety of applications for rejecting conducted noise. The T8003NL is a 3-phase common mode choke which is designed for use in variable frequency drives (VFDs). This application note provides an overview of the application fields and working principle of the T8003NL.

The T8003NL is designed for use in 3-phase motor control and inverter applications. It provides high commonmode impedance at medium to high frequencies, and can be used to reduce commonmode noise generated from power supplies, VFDs, inverters, and other 3-phase motor control systems. The T8003NL is also suitable for applications such as machine control, automotive, instrumentation, HVAC, and telecommunications.

The T8003NL is a nonpolarized electromechanical device, which can be used for both common and differential mode noise reduction. The T8003NL consists of three identical, ferrite toroidal cores wound in a special configuration. It is designed such that the windings are interleaved in order to reduce the electromagnetic coupling between the windings and thus increase the common mode inductance. This, in turn, reduces the common mode noise generated by the system.

The T8003NL features a high commonmode impedance across its operating frequency range, from 20kHz to 200kHz. The high commonmode impedance ensures a low noise transfer between the system’s power and signal lines, thereby improving the system’s overall system performance. The T8003NL also has a high commonmode current rating, allowing it to operate reliably even with high commonmode currents. Additionally, the T8003NL also features a wide commonmode ripple rejection range, up to 70dB at 100kHz.

The T8003NL also features a built-in temperature compensator, which helps to ensure consistent performance over a wide range of temperatures. This feature helps to prevent any undesired power fluctuations due to temperature variations. The T8003NL also features an optimized thermal resistance, which helps to ensure reliable operation over a wide range of temperature environments.

The T8003NL is a nonpolarized device and does not require any external connection. This makes it easy to install and use in systems. The device is also designed to withstand a wide range of temperature variations, making it suitable for a variety of environments.

The T8003NL is an effective solution for reducing common mode noise in 3-phase motor control and inverter systems. Its high commonmode impedance, high commonmode current rating, wide commonmode ripple rejection range, and built-in temperature compensator make it an excellent choice for today’s demanding applications.
