Common Mode Chokes (CMCs) is a type of electronic component, variously known as a line filter, line reactor, or differential-mode choke. It is an inductor used to block high-frequency noise generated by power supply in an electronic circuit. This article examines the application field and working principle of one specific type of CMC – the CM0805D900R-10.

The CM0805D900R-10 is a very common type of CMC and is widely used, both in consumer electronics and in industrial applications. It is suitable for use in a wide variety of switching power systems and other electronic applications, including medical, automotive, telecom, and even defense and aerospace equipment. This CMC offers high current capacity under both differential and common-mode conditions and operates over a very wide frequency range.

The CM0805D900R-10 works by inducting a magnetic field, created by the current flowing through its windings. This magnetic field blocks high-frequency noise, while still allowing normal signals to pass through. Because it is a symmetrical component, it can block noise in both the differential and common-mode. As such, it is designed to reduce the effects of Electro Magnetic Interference (EMI) on signals, whether those signals originate from outside noise sources or within the system itself.

The component is also designed to provide low impedance for the intended frequency range, while simultaneously reducing impedance at higher frequencies. This allows them to be used as AC line filters, dramatically improve the system’s power efficiency and reliability. Additionally, it offers excellent high-frequency suppression characteristics, making it especially well-suited for use in power switching circuits.

In conclusion, the CM0805D900R-10 is a common type of CMC, widely used in consumer electronic and industrial applications. It works by inducting a magnetic field, which blocks higher frequencies, while still allowing normal signals to pass through. This CMC can also reduce EMI effects, while providing low impedance for the intended frequency range. Furthermore, it offers excellent high-frequency suppression characteristics, making it ideal for power switching circuits.
