BMB2A0120AN4 Filters

Ferrite beads and chips are used to suppress EMI interference caused by high frequency currents. The BMB2A0120AN4 is a versatile ferrite chip used in variety of applications. It is compatible with both power and signal lines and is able to reduce both common mode and differential mode noise. This guide will cover the BMB2A0120AN4\'s application field and working principle.

Application fields

The BMB2A0120AN4 is designed to suppress high frequency noise on power and signal lines in a variety of fashions. It is used in areas such as medical imaging systems, solar power inverters, and industrial controllers. It is also used in automotive applications and as a EMI filter for consumer electronics. The ferrite chip is capable of suppressing EMI interference up to an attenuation of -15dB.

Working Principle

The BMB2A0120AN4 ferrite chip works by reducing conducted noise on power and signal lines. It does this by creating a low impedance path to ground for high frequency currents while maintaining a negligible impact on low frequency signals. As electrical currents encounter the chip, high frequency currents are diverted to ground, avoiding the sensitive components within the circuit. It is also used to reduce conducted noise by increasing loop inductance, allowing it to absorb any common mode currents that would otherwise lead to interference.

Installation

Installation of a ferrite chip is relatively easy, allowing one to quickly reduce EMI interference on power and signal lines. The ferrite chip can be installed either physically to the power or signal line or mechanically by wrapping the chip around them. It is important to note that using too many ferrite chips can increase loop impedance and cause a negative impact on system performance. Use only as many as necessary to reduce EMI and protect sensitive components.

Conclusion

The BMB2A0120AN4 ferrite chip is an efficient and reliable noise-reducing device for a variety of applications. It is capable of suppressing EMI up to an attenuation of -15dB and is used in fields such as medical imaging systems and solar power inverters. Proper installation of the ferrite chip can effectively reduce noise on power and signal lines, allowing components to operate without interference.
