Common Mode Chokes, or CMC’s, are a type of device used to reject common or normal mode noise in an electrical circuit. The device is designed to reduce the noise emitted from an electrical circuit while allowing desired signals to pass through. The DFKF-28-0004 is one such device optimized for use on data and power networks. It is specifically designed to protect these networks from voltage transients, crosstalk, and EMI.

The DFKF-28-0004 has powder core construction that improves inductance while allowing for higher acceptance of EMI-like signals. Its terminals are made with aluminum material that helps to dissipate heat and prevents the device from overloading. The device also has a wide pass band, which improves signal transmission and minimizes EMI interference. This means that the device is suitable for both high frequency and low frequency applications.

The DFKF-28-0004 operates on a new, patented technology which provides better noise immunity and power flow. It is designed to reject both high frequency and low frequency signals and can handle up to 40 watts of power with good efficiency. Furthermore, the device has excellent ESD protection which makes it safe to use in data and power networks where there is a risk of static electricity.

The DFKF-28-0004 is suitable for a variety of applications, including automotive, industrial, communication, or consumer electronics. It has a number of advantages which make it a popular choice for noise filtering and voltage transient protection. The device is able to reject most common mode noise and provide superior EMI and ESD protection. Additionally, its powder core construction and aluminum terminals help to dissipate heat, which allows for better performance and longer lifespan.

The DFKF-28-0004 works by rejecting common mode noise through the principle of inductive coupling. This occurs when two loops are placed close to each other, and one loop is the source of the noise. The other loop acts as a trap for the noise, allowing the desired signal to pass through but reducing or eliminating the noise. This phenomenon causes the noise, which is usually in the form of a high frequency signal, to be blocked by the device. This allows for more clean and reliable signal transmission.

In conclusion, the DFKF-28-0004 is a Common Mode Chokes device that is ideal for use in both data and power networks. Its powder core construction and aluminum terminals make it suitable for high and low frequency applications. Furthermore, its patented technology provides excellent noise immunity and power flow. The device is also capable of rejecting common mode noise through the principle of inductive coupling, which reduces or eliminates the noise and allows desired signals to pass through. All of these features make the DFKF-28-0004 an excellent choice for applications where noise reduction and signal protection are critical.
