Common Mode Chokes

B82796C113N201 is a common mode choke, which is a device consisting of an electrical coil and a ferrite core, stacked together and wrapped with a sheath. Common mode chokes are mainly used for preventing spurious noise from entering a circuit, to suppress common-mode noise caused by a change in the current flowing through the two lines. In this way, a common-mode choke acts as a filter, in order to improve the quality of the signal.

The B82796C113N201 provides an effective way to reduce electromagnetic interference (EMI) and unwanted stray currents in power and communications cables. The device can be used to reduce radiated and conducted EMI in the frequency range of 1-30 MHz. The device provides good common-mode insertion loss, low differential-mode insertion loss and excellent attenuation at high frequencies. The device is designed with a robust construction and insulation which can withstand up to 1.5 kV.

The working principle of the B82796C113N201 is based on the concept of "inductance" or the generation and storage of magnetic energy. By passing a current through the windings of the device, the strength of this magnetic field increases, which then opposes any change in the current passing through the device. This phenomenon creates a "reactive impedance" which reflects the flow of current. The magnitude of this reactive impedance depends on the number of turns of the winding, the size and permeability of the core, and the frequency of the current.

The B82796C113N201 is often used in many industrial, military and automotive applications. In power supplies, the device can be used to reduce the interference generated by the switching noise from the power supply. In motors, the device can reduce the normal switching-interference noise characteristic of high-speed motors. In communication systems, common mode chokes can be used to reduce the noise generated by cables and other external sources.

Due to its wide application field and efficient working principle, the B82796C113N201 is a popular choice for many industrial, military and automotive applications. It is also a relatively cost-effective solution as it offers good attenuation characteristics at a competitive price point.
