Common Mode Chokes are a type of electrical component used as a low-pass filter for high frequency, differential signals, allowing high frequency noise or differential signals to pass, while blocking out low frequency noise, or signals between differential line pairs. The PLY17BN9320R6B2B is a common mode choke designed to block out both high and low frequency noise in common mode, allowing only the differential signals to pass between the two terminals. This is important for applications where noise suppression is critical or when the differential signals must be completely isolated from each other.

The PLY17BN9320R6B2B Application Field includes uses in heavy industrical power supplies and in Power over Ethernet (PoE). The PoE Application requires the device to be suitable for operations up to 65W of power, and the industrial power supplies require the device to be able to handle up to 100W of power. The device also finds applications in automotive wiring harnesses, home theater electronics, medical devices and more.

The Working Principle of the PLY17BN9320R6B2B is based on its construction. The device is composed of two separate components, a differential mode part and a common mode part. The differential mode part works by allowing the differential signals at the two terminals to pass through with minimum resistance. The common mode part, on the other hand, works by blocking the common mode signals between the two terminals, which will typically be the low frequency noise. This way, any high frequency noise or differential signals present will be allowed to pass through while low frequency noise or signals between the two terminals will be blocked out.

The common mode choke also uses a High Frequency (HF) choke in conjunction with the basic components. The HF choke helps to further reduce the amount of high frequency noise signals that pass through the device, thus providing additional noise suppression. The choke is typically composed of a Ferrite core, a copper wire wound around the core, and an AC voltage source connected to the wound copper wire. When the voltage source is applied, an electromagnetic field is created, which absorbs and hinders the passage of high frequency noise.

The typical structure of the PLY17BN9320R6B2B is also important to understand in order to understand how the device works. The device is composed of two main parts, a winding section and a core section. The winding section is made up of two separate windings, one for the differential mode and one for the common mode. The windings are made from copper wire, wound around a core, which can be made from Ferrite, iron powder, or some other material. The core is responsible for absorbing any excess energy from the electromagnetic field created by the two windings.

The PLY17BN9320R6B2B also features an additional layer of protection against high frequency noise. This additional layer is called a C-RBC coating, which is applied to the core of the device. The C-RBC coating helps to further reduce any high frequency noise that may be present in the environment, thus providing additional noise suppression.

Overall, the PLY17BN9320R6B2B is a Common Mode Choke designed to provide optimal protection against high and low frequency noise. The device works by allowing differential signals to pass through the two terminals while blocking any low frequency noise or signals between the two terminals. The device also features an additional layer of protection in the form of a C-RBC coating, which helps to further reduce any high frequency noise present in the environment. The device is suitable for applications such as heavy industrial power supplies, PoE applications, and automotive wiring harnesses, among many others.
