Common mode chokes, or bifilar windings, are widely used in electronic circuits to reject electromagnetic interference (EMI) signals and mitigate power line disturbances. They are most commonly used to filter power supplies and incoming signal lines. The B82726E6203B041 is a common mode choke specifically designed for automotive applications and is widely used due to its reliable and robust nature.

The B82726E6203B041 is a filtered inductor coil with a diameter of 19mm, a height of 11.3mm, and a weight of 13.2g. It features a 100µH inductance value and a 0.162 ohm resistance value. It is rated to carry up to 9A of current and can handle up to 400 Vrms of continuous peak voltage. The B82726E6203B041 is designed with two windings in a “Bifilar” arrangement, meaning that it features a core with two independent windings that are wound in parallel and then interconnected at the core. This configuration gives the B82726E6203B041 the ability to reject common-mode interference while preserving signal integrity on the line. The B82726E6203B041 also features an epoxy-filled casing to protect against water, oil, and dirt.

Common mode chokes can be used in a variety of applications, from power supply filtering to reducing unwanted EMI noise in signal cables, as well as suppressing RF interference in radio and communication equipment. In power systems, common mode chokes can be used in power lines to reduce common-mode noise between the power lines and the ground. This helps to reduce interference and power loss to ensure a clean and reliable power signal. In data and signal systems, common mode chokes can be used along input and output cables to reject common mode interference between the cables and the ground. This ensures that the signal is not degraded by common mode interference and helps to preserve signal integrity.

The working principle of the B82726E6203B041 is fairly simple. The two windings work together to effectively cancel out any common-mode noise that passes through. When noise passes through the windings, it creates an equal and opposite voltage, which is called an inductive reactance. This reactance works against the noise and cancels it out, thus acting as a filter. The B82726E6203B041 also has a lowpass filter, which works in conjunction with the inductive reactance to further filter out high frequency noise. The combination of the lowpass filter and inductive reactance creates a highly effective filter that allows only the desired signal to pass through with minimal interference.

The B82726E6203B041 is an effective and robust common mode choke that is well suited for use in automotive applications. Its small size and robust nature make it ideal for use in confined spaces, and its ability to reject common mode noise makes it ideal for filtering power supplies and reducing unwanted EMI noise in signal cables. Furthermore, its lowpass filter helps to further filter out high frequency noise, making it an ideal choice for automotive applications.
