Power Line Filter Modules: B84112G0000M020 Application Field and Working PrinciplePower Line Filter Modules have become the go-to solution for protecting electronic circuits from voltage spikes and disturbances in the power line. The B84112G0000M020 Power Line Filter Module is one of the latest such solutions from TDK Corporation, and it offers many advantages. In this article, we will explore the B84112G0000M020’s application field and working principle in detail.The B84112G0000M020 is a good choice for applications such as motor drives, power supplies, and switch-mode power supplies. It is also suitable for use in medical and industrial equipment, as well as in instrumentation equipment. The filter is able to reduce interference levels by as much as 50 dB at some low frequencies, and it provides up to 2 KV EMI/RFI read more shielding.The B84112G0000M020 is designed with an integrated low-pass filter and high-pass filter, which provides excellent filtering capabilities. It is also capable of suppressing noise and EMI/RFI from interfering with the signal. Its integrated capacitor reduces the voltage drop from the supply rail, thus protecting the circuit from overvoltage conditions.The B84112G0000M020’s working principle is simple. It consists of two main components: an N-pole filter and a P-pole filter. The N-pole filter creates a low-pass filter that blocks high-frequency signals, such as EMI/RFI, from entering the power line. The P-pole filter is a high-pass filter that blocks low-frequency signals, such as line noise, from entering the power line. Together, these two filters form a bridge that effectively filters out both high and low-frequency signals.The B84112G0000M020 is also designed with various capacitors that reduce voltage drops, providing further protection to the circuit. These capacitors are also used to filter out high-frequency components, as well as to provide a ground loop for noise suppression. The B84112G0000M020 also has an integrated TVS diode that protects the circuit from any overvoltage events.In conclusion, the B84112G0000M020 Power Line Filter Module from TDK Corporation is an excellent solution for protecting electronic circuits from voltage spikes and other disturbances in the power line. It is capable of reducing interference levels by as much as 50 dB at certain low frequencies, and it offers up to 2 kV of EMI/RFI shielding. Its integrated low-pass and high-pass filters effectively block both high- and low-frequency signals, while its capacitors reduce voltage drop and provide ground loop noise suppression. Finally, its integrated TVS diode provides further protection from overvoltage conditions.
