Common Mode Chokes are used widely in the field of electromagnetic interference(EMI). One of the leading common mode choke models is the H6500NL, which is utilized by numerous industries. This article discusses the application fields and working principles of H6500NL.

Application Fields of H6500NL

H6500NL has a very broad range of applications, such as automotive, aerospace, military, and defense accessories, as well as instrumentation, laboratory, and industrial electronics. The most common use for this model is in the automotive sector, where its ability to reduce EMI interference is essential for the safety and efficiency of vehicle operations.

The H6500NL is the most preferred choice for low voltage, medium frequency, and low impedance EMI applications. It is capable of providing high insulation resistances to minimize interference, as well as excellent surge current performance. Furthermore, its robust construction, which includes the use of high-temperature-resistant insulation materials, ensures that it is resistant to high-voltage applications.

The H6500NL is also popular in the aerospace industry, where space-saving features are very important. Its wide operating temperature range and shielding capabilities make it well suited for operations under extreme weather and spacecraft conditions. Its longevity and dependability are also key factors in its popularity in the aerospace sector.

Working Principle of H6500NL

The working principle of the H6500NL is based on the combination of two different inductors. The first inductor is designed to reduce common-mode noise. This is a noise that flows in both directions, thereby creating a cross-connection. The second inductor, which is also referred to as the "plate inductor," further reduces this noise by reducing the gap between the two different currents. When combined, these two inductors create an effective EMI solution for reducing common-mode interference.

The H6500NL utilizes two sets of wires that are commonly connected together. The first of these wires, known as the "primary" wire, is designed to maximize the current through the choke. The second set of wires, referred to as the "secondary" wires, is designed to reduce the overall noise levels. During operation, the primary wires are under high current, thus creating a high inductance, while the secondary wires are kept in a low-inductance state. This helps to eliminate the exchange of current between the primary and secondary wires, resulting in a very low-noise environment.

In addition to reducing common-mode noise, the H6500NL is also capable of providing excellent insulation. This is because the combination of the two sets of wire creates an effective Faraday cage, which blocks any incoming electromagnetic interference. This helps to maintain the integrity of the data being processed and to greatly reduce the risk of system or device damage caused by EMI.

Finally, the H6500NL also offers a wide range of surge protection levels. This is because the combined wires act as a capacitor, which helps to reduce any incoming surges. In summary, the H6500NL provides excellent protection against EMI, excellent insulation, and reliable surge protection capabilities.
