Common mode chokes have been used for many years to reduce electromagnetic interference, particularly in power electronics. BX8213LNL is a common mode choke which is designed to provide high common mode rejection ratio (CMRR) and low electromagnetic interference (EMI) to power supplies, signal lines, and various communication systems. BX8213LNL is available in various sizes ranging from 3.0mm x 8.0mm to 8.0mm x 11.0mm, with a maximum current rating of 3 Amp.

Application Field

BX8213LNL is typically used in any application which requires an efficient filter to reject common mode noise. It is well suited for use in very high frequency applications such as power line harmonic filters, power factor correction, active front end transformer systems, and motor drives. It can also be used in a variety of other applications such as automotive, telecom, avionics, home automation, and industrial automation. Furthermore, BX8213LNL is ideal for noise prevention in high speed networks, such as Ethernet, Fibre Channel, and Token Ring.

Working Principle

The BX8213LNL is a common mode choke which works by creating an inductive impedance in the common mode noise, thus rejecting it from the signal lines. This is accomplished by utilizing a core wound into two separate windings in series and connected in differential mode. Each winding consists of a primary and a secondary winding, which are connected to the edge of the core. This structure allows the BX8213LNL to reject common mode noise and any other kind of noise that is present on the signal lines. The primary windings also work in conjunction with the secondary windings to further reduce noise.

The BX8213LNL is capable of providing a high common mode rejection ratio, typically surpassing -35 dB at 100 MHz. The core material is made of ferrite, which provides excellent noise reduction. It is also designed to be very robust, with an operating temperature range of -40°C to +105°C. This makes the BX8213LNL suitable for use in a wide range of industrial, automotive, and other applications.

In summary, BX8213LNL is a common mode choke designed to provide high common mode rejection ratio and low electromagnetic interference to power supplies, signal lines, and various communication systems. It is applicable for a wide range of applications, such as automotive, telecom, avionics, home automation, industrial automation, power line harmonic filters, power factor correction, active front end transformer systems, and motor drives. The BX8213LNL is capable of providing excellent EMI and CMRR performance, making it an ideal choice for noise prevention in high speed networks.
