Common Mode Chokes utilize two or more inductors to form a wide band interference filter that prevents noise from propagating from one device to another. By blocking common mode noise, it helps to maintain a reliable signal quality between the devices. The 7448640411 is a common mode choke that is widely used in many applications. This article will discuss the application field and working principle of this device.
The 7448640411 is commonly used for in-vehicle electronic control units, engine ECUs, and car audio systems. It can be used to reduce common mode interference from electrical noise caused by the switching of the power devices such as MOSFETs and IGBTs. It can also be used to reduce noise generated by an automotive alternator or battery. It can also be used to reduce pulsed noise caused by the spark-ignition of the engine.
The 7448640411 is a high-frequency, bi-directional common mode choke that can effectively reduce noise from a wide range of sources. It has high frequency characteristics and high impedance in the common mode, while having low impedance in the differential mode. This allows it to filter out any unwanted common mode noise that would otherwise interfere with the operation of connected equipment.
The 7448640411 is capable of filtering out up to 100MHz of noise, with a common mode attenuation of 35 dB. It can also provide differential mode noise attenuation of up to 10 dB. This makes it suitable for a wide range of applications ranging from automotive electronic systems, to computer systems, and audio systems.
The working principle of the 7448640411 is quite simple. It utilizes two inductors, one for each line of the signal, which is connected in series. The inductance of the inductors is the same, so when a current flows through one of the inductors, the other one will be subjected to a back electromotive force that is equal and opposite in direction. This back electromotive force will then oppose the flow of current, causing the signal to be attenuated.
This effect is further amplified when the inductors are connected in parallel with each other. This increases the total inductance, resulting in a greater attenuation of the signal. The 7448640411 is thus capable of providing effective noise filtering in both the common and differential modes.
In conclusion, the 7448640411 is a common mode choke that can be used in a wide variety of applications. It is capable of providing effective filtering of common mode noise at a wide range of frequencies. Its working principle is based on the use of two inductors connected in series or parallel, which work to reduce noise through back electromotive force opposition.
