Common Mode Chokes

Common mode chokes, also referred to as CM chokes, are electric current filters which reduce electrical noise in power lines. Common mode noise is generated when two or more circuits carry similar, but opposite electrical currents. The most common applications for CM chokes are power supplies, audio amplifiers, and laptop computers. There are two main types of CM chokes - those with an inductive circuit and those with an active filter.

The MCZ2010DH900L4T000

The MCZ2010DH900L4T000 is a common model mode choke used in a variety of applications. It is a high-frequency, high-performance common mode filter for DC/AC/RF power circuits. The MCZ2010DH900L4T000 uses an active filter to reduce common mode noise in the power line. It has a high stop frequency of over 800MHz, making it suitable for a wide range of applications, including telecommunications, automotive, industrial, and consumer applications.

Application Field of MCZ2010DH900L4T000

The MCZ2010DH900L4T000 is typically used in applications where high frequency common mode noise needs to be minimized. It can be used in power supplies and switching power supplies, audio amplifiers, laptop computers, and motor control systems. It is also used in the automotive industry to reduce common mode noise in windshield wiper and electric window motor controllers, airbag systems, and ABS systems.

Working Principle of MCZ2010DH900L4T000

The MCZ2010DH900L4T000 works on the principle of an active filter. It consists of an inductor in the center of the filter and two capacitors, one on either side of the inductor. The capacitors are used to reduce the amount of high frequency current that is allowed to pass through the filter. The inductor, on the other hand, is used to reduce the amount of high frequency voltage that is allowed to pass through the filter. The result is that the filter effectively blocks any high frequency common mode noise from being transmitted through the power line, while still allowing lower frequency signals to pass through.

The MCZ2010DH900L4T000 is a high-performance filter that can handle frequencies up to 800MHz. It is ideal for applications that require high frequency noise reduction, such as telecommunications, automotive, industrial, and consumer applications. It is typically used to reduce common mode noise in power lines, audio amplifiers, and laptop computers.
