Common Mode Chokes
A common mode choke (CMC), also known as a common mode inductor, is an electrical device used to reduce electrical noise and interference that may interfere with the operation of electrical circuits and equipment. The CMC helps to reduce the amount of signal noise that is present in an electrical system, typically by providing a magnetic field of opposing fluxes near the source of the noise, thereby canceling or reducing the noise before it can reach the sensitive components of the system.
The DLW21SZ900HQ2L is a common mode choke designed for use in applications including switched mode power supplies (SMPS), radio frequency (RF) circuits, low frequency circuits for audio, medical equipment, communication equipment, industrial equipment and automotive applications. It is available in a variety of package type and sizes and comes with a rated current of 21.4 amps.
Working Principle
The DLW21SZ900HQ2L common mode choke works by providing a high impedance path to common mode noise from the noisy circuit, thereby diverting the noise away from the sensitive components in the circuit. This high impedance path, usually provided by an inductor, works by varying the amount of current it takes to achieve a given voltage level. The more current it takes, the higher the impedance and the more noise is “canceled” in the system.
The DLW21SZ900HQ2L performs this task by using a combination of low profile, high quality ferrite core material and specialized windings to form a balanced current loop in the common mode. The current level of the windings is always equal and opposite to cancel out any existing common mode noise. This results in fewer errors in noise measurements and an overall improved signal-to-noise ratio.
Applications
DLW21SZ900HQ2L is most commonly used in applications where reducing or eliminating common mode noise is required. This can include switched mode power supplies, radio frequency circuits, audio systems, medical equipment, communication equipment, industrial equipment and automotive applications.
In SMPS designs and other high frequency circuits, it can be used as an input filter to reduce noise and ripple on the input power lines. It can also be used to reduce the undesired noise being transmitted to the neighboring circuits, reducing emissions interference. In radio frequency circuit designs, it can be used to reduce the coupling of unwanted signals to the circuit, resulting in improved signal reception. In medical and communication applications, it can reduce the amount of error in signal transmissions, resulting in improved security for sensitive data.
Conclusion
In conclusion, the DLW21SZ900HQ2L is an effective common mode choke that can be used to reduce or eliminate common mode interference and improve signal-to-noise ratio in a variety of applications. Its simple design and compact size make it ideal for use in a wide range of applications which require a high level of noise reduction.
