Common Mode Chokes are a type of electronic component created to diminish or eliminate common mode noise on cables or circuits. The CM3822R800R-10 is a particularly useful model in this respect, as it has the capability to block or isolate noise interference at up to frequencies of 800MHz.

This model is a common mode choke coil with a compact design, making it ideal for use in a range of different applications. It can be used for multiple signal sources, as it has a high-density impedance and high power rating. Designed to suppress differential and common mode noise and reduce reflections, the CM3822R800R-10 offers excellent performance in its size class.

The CM3822R800R-10 is available in two versions: vertical or horizontal. The vertical version features a common mode inductor with a full winding that provides higher choke performance in space-constrained areas, as well as a lower operating temperature. The horizontal version has a single-sided winding, making it ideal for higher power applications where the higher temperature can be tolerated.

The CM3822R800R-10 is a flexible yet durable component capable of withstanding temperatures up to 105°C. It has long-term reliability and features a max-DC current of 1.2A, and a max-RF current of 0.5A. The coil size is small enough to enable integration into various systems and variable boards, without compromizing performance.

The working principle of the CM3822R800R-10 is based on a transformer principle, where the dual windings isolate electrical noise. It creates a wide band of frequencies that blocks the noise from passing through. This is done by generating high impedance in the frequency range, and low impedance in the range of the noise. It also creates a magnetic shield that can contain the noise from exiting, ensuring an optimal level of performance.

Being a wideband component, the CM3822R800R-10 is not dependent on frequency and operates effectively at harmonic frequencies, a property that makes it suitable for several applications. As previously mentioned, it is often used to filter electromagnetic interference (EMI) on various signal sources. It is also used in many automotive applications, such as speed sensors, and for suppressing common mode noise from power amplifiers used in radio and TV transmitters.

The CM3822R800R-10 is an efficient way to reduce or eliminate common mode noise. Its wide range of capabilities makes it a viable option for many devices, and its small size makes it particularly suitable for high-density PCB designs. It is also extremely durable, allowing for a long service life.
