CM3322P400R-10

CM3322P400R-10 is one of the most popular Common Mode Chokes (CMC) on the market. Common Mode Chokes (CMCs) are functionally generated current filters used to reduce electromagnetic interference (EMI) in power, communication, and other applications. They are usually used in circuits to reduce the electrical noise generated by the power supplies and signals.The CM3322P400R-10 is mainly designed using ferrite core material with 0.40mm – 10.3mm size. The operating temperature range of this Common Mode Choke is -40°C ~ +110°C, and its impedance is 80 – 600 ohms. It has a small form factor and is well suited for small board spaces. The CM3322P400R-10 is also compatible with lead-free and RoHS standards.The main application areas of the CM3322P400R-10 include power supplies, communication electronics, personal computers, and medical equipment. These components are mainly used for EMI suppression in higher frequency circuits, such as EMI filter in laptop computers. Also, they can be used in automotive power switches and headlights, Led lighting fixtures, and consumer electronics.The working principle of the CM3322P400R-10 is based on the magnetic field effect. It uses a portion of the coil to block the common-mode EMI noise, reducing the effects caused by the noise.The CM3322P400R-10 is a passive device that works by creating a magnetic field around the wires, blocking any EMI noise. It uses the inductance feature of the ferrite core material to reduce the common-mode noise generated by the cable and power line. The inductors sink away the noise, while the capacitors store the noise. When the power supply and connectors are not close to each other, the EMI noise is blocked by the inductance of the coil.The CM3322P400R-10 can attenuate the EMI noise and reduce its intensity to meet the EMC requirements. It has a frequency range from 10kHz to 110MHz. It also features high insulation resistance, which allows the EMI noise to be effectively blocked between devices. The noise blocking effect of the CM3322P400R-10 is higher at higher frequencies.To sum up,the CM3322P400R-10 Common Mode Choke is especially designed to suppress EMI noise and reduce its intensity. It is suitable for power supplies, communication electronics, medical equipment, and other high frequency circuit design. With its features of small form factor, high insulation resistance, and wide frequency range, the CM3322P400R-10 makes it an ideal choice for many high-frequency applications.
