Common Mode Chokes are an important family of electrical components used to block the common-mode noise from a signal. The 8119-RC series of common mode chokes are specifically designed to suppress differential-mode noise from automotive and telecom applications.

A common mode choke is composed of two symmetric coils wound on ferrite cores and connected in series with opposite polarities. This creates a magnetic field which opposes the current flow in the two coils, thus producing a strong magnetic field with a large inductance. The inductance created by this type of choke is generally much greater than that of a normal series choke. This allows the 8119-RC to provide effective shielding against common-mode noise in applications.

The working principle behind the 8119-RC common mode choke is to provide a path of high impedance for the current in both directions. This high impedance helps to minimize the effect of the common-mode current on the signal quality. The high impedance also helps to reduce the residual voltage and noise generated by the common-mode current. By creating a strong magnetic field, the 8119-RC can effectively reduce the level of common-mode current present in the system.

The 8119-RC common mode choke also provides a wide frequency response, ranging from approximately 10 MHz to 1.8 GHz. This wide range makes the 8119-RC ideal for use in high-speed data transmissions, such as automotive and telecom applications. In addition, these common mode chokes are designed to perform well in noisy environments, such as in industrial and medical applications.

In automotive applications, the 8119-RC series of chokes are used to reduce noise from the alternator and engine, as well as reduce any static in the transmission line. They are also used to reduce the amount of voltage and current spikes that can be generated when adverse conditions occur, such as rapid changes in the speed of the vehicle or when the alternator is not operating correctly.

In telecom applications, the 8119-RC series of common mode chokes are used to reduce the amount of differential-mode noise in the transmission line. This helps to maintain a high-quality signal for long-distance transmissions. The wide frequency range of these chokes also allows them to be used in applications requiring high-bandwidth, such as wireless networks.

The 8119-RC series of common mode chokes are designed to provide superior performance in a variety of applications. They are robust and durable, and can be used in a variety of environments, from automotive and telecom applications, to industrial and medical applications. The wide range of frequencies provided by these chokes allows them to be effectively used in a variety of applications.
