Common Mode Chokes

Common mode chokes—also referred as line filters—are components consisting in coils which are used in order to reduce signals or AC current passing through electric circuits, they are commonly used in electronic, electrical and automotive systems, such as the SS20H-10080 models. Common mode chokes come in different types, either double-sided or single-sided, however, the SS20H-10080 model is double-sided. It has two coils in a can structure. It has two mounting pins, one on each side of the can. This pin is paired with a mounting bracket and used to hold the choke in place. The can is sealed with a plastic or metal lid.There are a few different types of common mode chokes. These include: high current, high frequency, shielded, split-bobbin and multiple-coil chokes.The SS20H-10080 model is a high frequency common mode choke. Its main purpose is to reduce noise generated by a circuit, such as high-frequency noise generated by switching power converters or motors. This is accomplished by presenting a high impedance to noise signals, while still allowing for a low impedance path for the intended signal. The SS20H-10080 model consists of two main components, a core and a coil. The core of the model is made from Permeable ferromagnetic alloy (PC40 ferrite CN8550 material). The coil is made of enameled copper wire. The model also includes two mounting pins and a plastic lid to seal the can.The core and the coil of the SS20H-10080 common mode choke are designed to create inductance, hence, they are used to reduce the AC currents running through the circuit. The inductance presented by the internal parts of the common mode choke will form a low resistance path for the intended signal while creating a high impedance path for the unwanted noise. This is due to the fact the energy stored in an inductor is a function of the inductance and frequency of the signal. The purpose of mounting a common mode choke is to reduce the level of noise and ensure reliable operation of a circuit. By reducing the high-frequency noise, the common mode choke can improve the operation of a circuit, minimizing errors, ensuring more reliable data communication, and reducing electric disturbances.In the case of the SS20H-10080 common mode choke, its typical inductance range is between 1.2mH to 1.6mH. It has a maximum rated current at 25°C is 4A. Its operating temperature range is -40°C to +85°C and is compatible with an in-circuit operation. The frequency of operation ranges from 0 Hz to 1GHz. The SS20H-10080 common mode choke is widely used in different applications. It has been engineered for use in industrial and automotive systems, such as automotive auxiliary motors, automotive audio systems, electronic office machines, instrumentation, electric meters, HVAC systems, and other industrial applications.Overall, the SS20H-10080 common mode choke is an effective way of reducing noise and providing reliable operations in a circuit. It is a robust design and is highly efficient in suppressing high-frequency noise in automotive, industrial, and electronic systems.
