Common mode chokes are one of the most commonly used components in electrical engineering. From low-frequency isolation transformers to high frequency signal transceivers, they are used to transmit, control, and protect signals. The type B82506WA6 is a common mode choke designed by EPCOS AG. It is a miniature double-choke common mode filter. Double chokes refer to two coils arranged side by side with a common core in between them. The two coils share the same core, but they have different numbers of turns and therefore different inductance values.

The type B82506WA6 is a surface-mount common mode choke filter with an effective frequency range of up to 1000 MHz. The filter core is made of a ferrite material with an outer casing that is dipped to increase insulation. The filter is rated at a maximum current of among other parameters. The choke is designed for use with power lines for the suppression of common-mode interference.

Common mode chokes have two distinct working principles. The first is the inductive property of the choke, which is created by wrapping several turns of a wire around a ferrite core material. This induces an electromagnetic field in the core and results in a changing electrical current. This current produces an inductive back EMF, which resists change in current flow and is hence effective in suppressing noise. The second working principle is the capacitive property of the choke, which is created by the coupling of the two coils. This forms a capacitive transformer, which creates a dampening effect in the line and further reduces noise levels.

The type B82506WA6 is ideally suited for applications such as EMI/RFI suppression in circuits and data transmission lines. It can also be used as a line filter for power supplies, providing protection against line emission and interference. Additionally, it can provide improved signal integrity, longer communication distances, and superior power filtration.

The type B82506WA6 is a miniaturized, double-choke common mode filter that is an ideal choice for applications requiring isolation of power from data and noise suppression of high-frequency signals. It provides effective filtering up to 1000 MHz and an additional capacitive transformer that dramatically suppresses the line noise. With its efficient design and wide range of applications, it is a valuable component in many power and data systems.
