K-104 EMI CM USB is largely applied in filter kits. It is essential to control the self-induced noise generated from the power sources or other electric equipments, making sure the hazardous noise sources do not interfere with the electronics circuit. This kind of filter helps stabilize the performance in variable environment to prevent the various types of noise and high frequency interference. The following is the description of K-104 EMI CM USB application field and working principle.

Application Field of K-104 EMI CM USB

K-104 EMI CM USB filter is a kind of high efficiency filter kits developed with the application of high frequency EMI techniques. It can be used in the following areas:

• IEC/EN61000-3-2 and IEC/EN61000-3-12 no-load and low-inrush equipment
• High voltage suppression and high frequency interference
• Electromagnetic compatibility
• Electrical overload protection

K-104 EMI CM USB filter kits are widely applied in the electronics industry, such as computer, mobile phone, household appliances, immersion heating appliances, micro-wave oven, DC motor, TV set, audio equipments, automation machines, telecommunication equipments, and so on.

Working Principle of K-104 EMI CM USB filter kits

K-104 EMI CM USB uses EMI inductors, and SMD ferrite beads, and integrated capacitors to form the RF bypass networks. This filter is composed of two main parts, one is the inductance filter networks, and the other is the capacitance filter networks. The inductance filter networks are connected between the inlet line and the outlet line, while the capacitance filter networks are connected in parallel with the inductance filter networks.

When two types of filter networks work together, the combination of them creates the high frequency signals shielding effect to block the interference and noise. The suppression of the outside interference not only can protect the device itself, but also can reduce the interference to other facilities. Moreover, the high frequency interference reduction characteristic and the selectivity of the filter kits can optimize the frequency response of the signal, resulting in the improvement of the system reliability.

Besides, K-104 EMI CM USB filter kits are also designed to reduce the RFI or EMI perturbations from the high frequency oscillator and the high frequency circuit components. The inductance filter networks form the low-pass, band-pass, or high-pass filter, which can effectively suppress the interference from high frequency oscillator. Meanwhile, the capacitance filter networks will suppress the general RF noises. This kind of filter is suitable to be used in the open electrical environment, and also it has a good protection against destructive noises and surges.

K-104 EMI CM USB filter kits work as the high frequency interference suppressor, and also they can improve the electrical property, achieve the purpose of noise reduction and stability enhancement. In a word, the K-104 EMI CM USB filter kits are applied in many fields to ensure the good electrical performance and stability of the electronic equipments.
