Introduction to Common Mode Chokes

Common Mode Chokes are components used to block common mode noise from entering or leaving a circuit. The most common use of chokes is in power supplies, where the chokes help reduce the amount of EMI (Electromagnetic Interference) that gets through the filters in the power supply. Common mode chokes help to reduce the amount of noise that gets through the power supply by blocking the common mode currents. Common Mode Chokes are an essential part of any circuit which are designed to pass signals between a point such as a power supply and a load.

SS28V-R25080-CH Application Field and Working Principle

The SS28V-R25080-CH is a common mode choke component for power supplies. It is commonly used in many applications, including cell phone chargers, LCD displays, and automotive applications. The way it works is through the use of an electromagnetic field that creates a physical barrier which blocks common mode noise from reaching the load. The SS28V-R25080-CH contains two main parts. The first is the core, which consists of two small ferrite rings surrounded by two large horns. This is where the electromagnetic field is generated. The second part is the windings, which are made up of two coils wound around the core. This creates an inductor that produces an EM field around the core. The electromagnetic field that is created by the SS28V-R25080-CH helps to block common mode currents from entering or leaving a circuit. It works by blocking the noise in two ways: by creating an impedance barrier between the power supply and the load, and by creating a capacitive effect between the two terminals. The impedance barrier helps to reduce the amount of noise that is able to pass through the filter in the power supply, while the capacitors block the noise from entering or leaving the circuit. Overall, the SS28V-R25080-CH is a very effective way to reduce noise in power supplies. It works by creating an EM field that helps to block common mode noise from entering or leaving the circuit. This helps to ensure that only the desired signal is allowed to pass through the filter, and prevents the introduction of unwanted noise into the circuit.
