Common Mode Chokes

Common mode chokes, also known as common mode filters, are devices that are integral components in power quality and power supply applications, primarily designed to reduce EMI caused by electrical components such as variable/switched frequency drives and general commutation circuits. Common mode chokes are passive electrical components that can be used to reduce or limit differential mode and common mode interference on power, data, and even control lines.

B82734R2262B030

The B82734R2262B030 is a three-phase common mode filter that provides excellent common and differential mode noise suppression up to 200 kHz, making it useful in a variety of applications, from photovoltaic inverters to luminaire power supplies.

Application Field and Working Principle

The B82734R2262B030 is suitable for power supply applications, such as inverters, converters, and photovoltaic systems; commutations circuits and motor drives; etc. The common mode chokes are also effective in transmission lines, such as LAN cables, power cables, and motor controls lines, etc.

Common mode chokes work by limiting the flow of common mode currents by creating a noise barrier around the EMC-sensitive components of the system. This noise barrier consists of a number of inductive windings which limit the transmission of higher frequency noise over different distances. The principle of a common mode choke is that the electromagnetic field will couple with the LF winding but not with the CF winding. By limiting the transmission of higher frequency noise, the CF winding can reduce the amount of EMI leaking back into the system.

The B82734R2262B030 contains a winding and a ferrite core which is used to enhance the inductance of the winding. The winding and the ferrite core are arranged in such a way that the electromagnetic field will couple with the LF winding but not with the CF winding. This arrangement also reduces the return of EMI noise, allowing the system to achieve high levels of immunity to EMI noise.

The B82734R2262B030 also has a differential mode prevention effect, which helps to reduce interference in data, power, and control lines. In addition, the B82734R2262B030 provides excellent thermal performance, with an operating temperature range of -25 degrees Celsius to +125 degrees Celsius and a maximum operating temperature of 150 degrees Celsius.

Overall, the B82734R2262B030 is an ideal choice for applications that require high levels of noise suppression while ensuring good transmission of power. With its excellent performance, thermal capabilities, and differential mode suppression, the B82734R2262B030 is a great choice for a variety of power quality and power supply applications.
