Common Mode Chokes are electronic components used to filter out any electronic noise present in a signal line, whilst allowing the signal to pass unaffected. The B82734R2132B030 application field and working principle is no different.

This Common Mode Choke is used in applications such as switch mode power supplies, inverters, converters, and motor drives, as well as medical and automotive electronics – anywhere there is a need to reduce or contain electromagnetic interference (EMI) to minimize interference with other equipment.

The B82734R2132B030 is a low-resistance and high-impedance common mode filter, which can be used for both differential and single-ended signal filtering applications. Its design comprises of two conductors – a primary (i.e. inductor) and a secondary (i.e. capacitor) – which are electrically coupled via an air gap. The gap is filled with an insulating material such as ferrite, which helps to maintain the EMI level enhancements. The choke is also rated for a voltage of between 25 and 750VAC/1min.

The B82734R2132B030 has a ferrite core to provide a high-impedance path to EMI, while the inductance is typically set at 5 to 10mH. As noise enters the choke via the two signal wires, it is blanketed due to the effectiveinductance of the choke. The signals enter the core of the choke, pass through the capacitor, and then travel out to your system, free from EMI interference.

To further aid in eliminating EMI, the common mode choke features a capacitor on the primary winding along with a capacitor and resistor to provide filtering on the secondary side. The capacitor on the primary winding acts like a low-pass filter, while the secondary capacitor and resistor act as a band-stop filter. This combination helps to reduce common-mode noise or the sum of the interference signals coming from both the primary and secondary sides.

The B82734R2132B030 is designed to withstand temperatures up to 105°C and is also equipped with RoHS compliant terminals for easy soldering. In addition, it can withstand overloads up to 2.5 times the rated current.

The B82734R2132B030 common mode choke is a versatile and cost-effective electromagnetic interference (EMI) filter that can be used to filter out any noise present in a signal line, whilst allowing the signal to pass unaffected. It is designed to fit a wide variety of applications and offers excellent protection against unwanted EMI, enabling perfect operation of the system.
