Common Mode Chokes are passive electronic components used for reducing the amount of common mode noise in an electrical circuit. Common mode chokes are typically used in data or power transmission lines, as well as on AC power supplies. They are also important in RF applications, such as MRI, CAT scans, and ultrasound imaging.

B4003NLST is a common mode choke that is designed for electromagnetic interference (EMI) suppression in radio frequency (RF) applications. It is capable of providing a high level of attenuation over such frequencies as 0.5MHz-18GHz, making it ideal for many types of RF applications. The B4003NLST is constructed with spiral inductors within an epoxy closure, making it a low-profile option for many applications.

The principle of operation of a common mode choke is to apply a magnetic field to the transmission line and create a “null zone” within the bounds of the magnetic field. This prevents EMI from being transmitted or received by the choke. The choke also acts as a filter to reject any EMI that is introduced into the system. This effectively “shunts” the EMI away from the conductors, thus reducing the amount of interference in the system.

B4003NLST has many applications in RF systems. One key application is in site-specific radio frequency installations. Here, the use of a common mode choke is used to ensure that EMI from a nearby transmitter does not interfere with the radio signal of the installation. Another application is in the field of automotive electronics. Here, common mode chokes are used to help reduce the levels of EMI that can cause harm or degrade the performance of the vehicle. In addition, B4003NLST can be used to reduce EMI in audio systems, such as automotive stereos.

There are several factors to note when installing B4003NLST common mode chokes. It is important to ensure that the power supply is adequate for the choke’s requirements. Additionally, in order for the choke to be effective, the conductors of the line must be properly shielded. The choke must also be installed correctly, with the appropriate connections being made.

B4003NLST is a popular choice of common mode choke due to its ability to provide a high level of attenuation over a range of frequencies. Its low profile design makes it ideal for many applications, such as automotive and audio systems. When properly installed, it can be an effective way to reduce EMI in many RF systems.
