Common mode chokes, also called common mode inductors, are electromagnetic components, usually coils, that allow electromagnetic flux to only flow in one direction through a circuit. This type of component is designed to reduce noise from a circuit that has two or more conductors. This is done by blocking the unwanted current from entering while allowing the desirable current to pass unhindered. A common mode choke is also useful in preventing interference from other circuits. Common mode chokes are used to protect electrical and electronic circuits from interference from other signals, and provide a means of signal stabilization and filtering.ThePG1265NL, manufactured by Pulse Electronics, is a general purpose common mode choke. This surface mount component is designed to reduce common mode interference in low power electronic circuits operating in a frequency range of up to 1 MHz. This surface mount component is also designed with customizable center clip technology that allows the user to achieve the desired level of attenuation in a controlled impedance range. Additionally, the component includes an integral mounting clip for ease of installation.The PG1265NL is intended for use in low power electronic circuits in a wide variety of applications. These include telecommunications, USB, Ethernet, and industrial control systems. This component is also used in consumer electronics, driving motors, and automotive applications.

The working principle of a common mode choke is the same regardless of the type of inductor chosen. The inductors work by creating an opposing magnetic field when current passes through them. This prevents the current from traveling parallel to the wires and thus inhibits the unwanted signals from entering the circuit. The PG1265NL common mode choke works by allowing desired current to pass through unimpeded while blocking the undesired current. This is achieved through the combination of its parallel inductors and center clip. As the desired power is passed through the inductors, the center clip’s opposing magnetic fields block the unwanted current from passing through. This prevents interference from other signals entering the circuit and results in improved signal stability and filtering.The PG1265NL common mode choke also includes an integral mounting clip which allows for easy installation. This decreases the chance of shorts and ensures that the component is mounted in its optimal position for interference reduction.

In conclusion, the PG1265NL common mode choke is an excellent choice for reducing common mode interference in low power electronic circuits operating up to 1 MHz. This component is suitable for a variety of applications, including telecommunications, USB, Ethernet, consumer electronics, driving motors, and automotive systems. The PG1265NL works by allowing desired current to pass through while blocking undesired signals and is also designed with a center clip and an integrated mounting clip for ease of installation.
