Common Mode Chokes

Common Mode Chokes, or CMCs, are passive devices used in electronic circuits to reduce the amount of common-mode noise present on power and signal lines. They are used in a variety of applications, from residential power supplies to large industrial systems. The SS21V-110067 is a particularly popular CMC because of its moderate cost, small size, and high efficiency. In this article, we will examine the application field and working principle of the SS21V-110067.The SS21V-110067 is commonly used in power supplies, including those used to power a wide variety of appliances and equipment. It is particularly useful in providing protection against interference between different power sources, such as between an AC and DC supply, or between different AC sources. The SS21V-110067 is frequently used in Power Line Communication devices, and is often included on DC and AC power lines to reduce line noise and protect important components from transient noise. It is also commonly used in a variety of different communication systems, from wireless systems to optical networks.The SS21V-110067 is a passive device, meaning that it does not require an external power supply. Instead, it operates by reducing the common-mode noise on the power or signal line. This is done by creating a Faraday Cage, which is a screened enclosure composed of two or more conductive layers. By capturing the noise within the Faraday Cage, the SS21V-110067 prevents it from further propagating along the power or signal line.The SS21V-110067 is constructed with multiple high-frequency chokes wound on an E-core design. This design allows for a wide band of frequencies to be blocked, allowing the CMC to be effective in many different applications. The multiple chokes also provide additional noise insulation and filtering, as the stray capacitance and inductance that can be present in a single choke configuration is greatly reduced.In addition to its Faraday Cage design, the SS21V-110067 also has two additional components that enhance its performance. The first is a low-pass filter, which filters out all frequencies above a certain cutoff frequency. This allows the CMC to block out high-frequency noise, while still allowing the signal or data to pass through. The second is a series of capacitors, which provide additional protection by reducing impedance to the most common-mode noise frequencies.The SS21V-110067 is a reliable and efficient way to reduce the common-mode noise present on power and signal lines. Its Faraday Cage design, low-pass filter, and capacitors make it suitable for a variety of applications, from residential power supplies to industrial systems. With its reasonable cost, small size, and high efficiency, the SS21V-110067 is a popular choice among engineers and technicians.
