Common Mode Chokes (CMC) are a type of electronic component that is used to filter and suppress electromagnetic interference in electronic[ circuits. The B82791H2301N001 is a CMC that is designed for applications that require a very low-loss, high-frequency solution. It is used in a variety of applications such as signal and control lines, or any high frequency circuit where interference may be a concern. It is also used on power supply lines for telecommunication and video applications.

The B82791H2301N001 is based on a ferrite core construction, which allows for improved inductance and performance over traditional air core versions. It offers excellent shielding against a variety of frequencies, including AM/FM radio frequencies, lightning and EMI generated from computers. The inductance of the B82791H2301N001 ranges from 0.74 μH to 8.6 μH, and is rated for a maximum operating current of 2.5 A. It also features a low DCR of 0.21 mΩ and a high saturation current of 8.5 A.

When the current passes through the CMC, the choke will reduce or suppress the high frequency components of the current, while allowing the low-frequency components to pass through unaffected. This type of filtering is known as common mode filtering, and it is the primary function of CMCs. Common mode noise has frequency components that typically range from hundreds of kilohertz up to megahertz, which is beyond the range of traditional capacitors or resistors. The B82791H2301N001 also features an operating temperature range of -55°C to +125°C and a thermal dynamic resistance of 0.67°C/W. This allows the part to maintain its performance over a wide temperature range.

In addition to the common mode filtering, the B82791H2301N001 also features a differential mode filter, which is designed to protect against unwanted signals, such as those generated by appliances, that can be very damaging to sensitive circuits. This type of filter can reject signals that are common to both signal lines, usually those with frequencies below 10MHz.

Overall, the B82791H2301N001 is an ideal solution for high-frequency applications, where EMI suppression and noise immunity are critical requirements. It is designed to operate in high-temperature conditions, and offers excellent shielding against a wide range of frequencies. The integrated differential filter also provides additional protection against unwanted interference. For these reasons, it is an excellent choice for use in a wide range of applications in the telecommunications, video, and circuitry industries.
