Common Mode Chokes

The BX8191NLT is a common mode choke (CMC) with extremely high line EMI suppression performance. This product series is designed for use in AC power line applications, such as general-purpose EMI noise attenuation filters for consumer electronics or industrial-grade AC power line applications.

Application Field

The BX8191NLT provides excellent line EMI suppression capabilities for both differential and common mode EMI noise. The CMCs are available in a wide range of EMI suppression levels, ranging from low X and low Y to high X and high Y levels. Since the CMC provides appropriate EM1 performance at various levels, it is expanded its application field to medical, energy efficiency, IT and energy management areas.

BX8191NLT can be used for various types of machines, such as electric fan, air conditioner, washing machine, etc., and many industrial applications, such as sensing systems, smart grid, intelligent power grid and LED lighting.

Since BX8191NLT is ideal for the medical and energy efficiency area, some applications are the healthcare and medical industry. It can be used to power medical imaging systems, including ultrasound systems, CT scanners, etc. It can also be used in the home to reduce the interference of AC power line noise on medical monitors.

Working Principle

BX8191NLT combines common mode and differential mode EMI suppression in one component. Its working principle is simple and effective. It can be used to control the EMI noise in AC power line applications.

When connecting to a load, the CMCs will act as a resistance in the circuit to reduce or suppress the EMI noise, which affects the signal quality. The current flowing through the CMC creates an external magnetic field and a voltage drop over the CMC. This voltage drop creates a counter electromotive force which opposes the noise current and reduces the EMI noise generated by the load.

The CMCs are designed with high X and high Y X, Y dimensions and inductances, so they can create an external magnetic field more robustly and generate a voltage drop more effectively. This makes it possible to reduce or suppress higher levels of EMI noise than other common mode chokes.

The BX8191NLT is also designed to provide common mode noise suppressions for higher frequencies. Its design allows the CMCs to provide high-frequency noise suppression up to the 900MHz to 1GHz range.

The CMCs are also designed to operate in the highest temperature and humidity conditions, so they can be used in harsh environments, and they also have a long lifetime. All these features, together with its low cost, makes the BX8191NLT ideal for many EMI noise attenuation applications in various fields.
