Common Mode Chokes

Common Mode Chokes (CMC) are type of devices used to filter high frequency noise, and are widely used to suppress noise between two circuits that are connected to the same ground. This can be achieved when the CMC is used to provide a low impedance path to the high frequency noise currents while simultaneously providing a high impedance path to the common mode supply voltages.

7448640397 Application Field and Working Principle

The 7448640397 Common Mode Choke is designed for use in applications such as computer power supply, telecom systems, DC motors, power-line filters and many more. It can easily handle power levels up to 20W, meaning it\'s suitable for high-power systems.

The 7448640397 Common Mode Choke works by blocking high-frequency noise while allowing low-frequency signals, voltages, and currents to pass through. The CMC consists of two windings of a single wire, or a single winding of multiple wires. These windings have magnetic cores, allowing the induced current in the windings to provide a low resistance path for high-frequency signals while also providing a high-resistance path to common-mode supply voltages.

The 7448640397 Common Mode Choke works best when the windings are in opposition to each other. This opposition reduces the common-mode voltage and current, mitigating noise interference. The 7448640397 is able to achieve this while maintaining a moderate current rating and a low profile, saving on space. The choke also has a low DC-resistance, meaning it won\'t significantly reduce the system\'s performance.

Advantages

The 7448640397 Common Mode Choke offers many advantages over other filtering methods, such as its small size, low cost, high power capability, and low DC resistance. Furthermore, the device is able to filter out high-frequency noise while passing low-frequency signals, thus ensuring that the system remains performing at an optimum level.

In addition to providing reliable signal filtering, the 7448640397 Common Mode Choke also reduces the amount of Electromagnetic Interference (EMI), which can have a negative impact on the system\'s performance. By reducing the amount of EMI, the system\'s safety can be increased as well.

100% Test Coverage

To ensure that the 7448640397 Common Mode Choke can perform optimally, it undergoes rigorous testing in a state-of-the-art Quality Assurance Laboratory. This testing includes 100% life test coverage to ensure that the device functions optimally for its entire life. Furthermore, the Common Mode Choke is tested against static current, temperature, humidity, and vibration to determine its durability and ability to operate in harsh conditions.

Testing is also done to ensure that the device meets current safety standards. In particular, the 7448640397 Common Mode Choke is designed to meet UL 94V-0 requirements, ensuring fire-resistance and long-term reliability. With its high level of safety and EMI-reduction capabilities, the 7448640397 Common Mode Choke is a valuable tool for any system that requires reliable filtering.
