Electromagnetic interference (EMI) and radio frequency interference (RFI) are signals that interfere with or degrade desired signals in electronic devices. These forms of interference can be very problematic for both the quality of a device’s performance and the human end-users of the device. To protect sensitive electronic systems from EMI/RFI, BGF112E6328XTSA1 is designed. This EMI/RFI filter consists of LC and RC networks designed to block the signals and restricting any potential noise.

The function of the EMI/RFI filter lies in its construction. The BGF112E6328XTSA1 is a dual-layered EMI/RFI filter containing a series inductance (L) and a shunt capacitance (C). The inductor provides the high-frequency bypassing while the capacitor blocks high-frequency interference. Together, they form a low-pass filter to ensure that only frequencies below the cut-off frequency pass through while those above are blocked or otherwise attenuated.

The application of BGF112E6328XTSA1 primarily centers on consumer electronics and communication systems. The filter’s compact size makes it suitable for use in applications in which space is limited, such as computers, cellular phones, tablets, modems, and other communication equipment. By minimizing the impact of EMI/RFI on signal integrity, these filters can be used to provide reliable and robust signal reception in these devices.

The filter’s working principle is based on the physical phenomenon of impedance. The impedance of an electrical component can be thought of as the ratio of voltage to current, and is determined by the component’s capacitance (C) and inductance (L). BGF112E6328XTSA1 uses both L and C to form a low-pass filter. The inductive component of the impedance “blocks” high-frequency signals from passing through, while the capacitive component allows low-frequency signals to pass. This prevents interference while simultaneously preserving the desired signal.

The main advantage of BGF112E6328XTSA1 is its combination of high performance, low cost, and small size. Its low-pass filter effectively reduces the impacts of high-frequency EMI/RFI on a wide range of consumer electronics and communication systems, while its small form factor allows for easy implementation in limited space. As such, BGF112E6328XTSA1 is a cost-effective and reliable solution for keeping external interference out of sensitive electronic devices.
