Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) filters are devices designed to reduce or eliminate these types of interference in electronic devices. EMI and RFI filters are crucial components in any switch mode power supplies, power system, high-speed communication networks, and radio frequency based systems. In this article, we will discuss the application field and working principle of the SBSGP5000153MXR EMI/RFI filter.

The SBSGP5000153MXR EMI/RFI filter combines an Electro-Static Discharge (ESD) protection function and high-speed data line protection with an EMI/RFI filter function. This filter supplies EMI/RFI line noise protection for systems operating in the 150kHz to 2MHz frequency range. It can be used in motor drives, inverters, electronic ballast, audio/visual systems, computers/peripherals, and factory automation applications. It can also be used in automotive, commercial, scientific, and medical applications.

This EMI/RFI filter enables the user to minimize conducted and radiated emissions as well as filter out conducted noise and interference. It contains both conductive and non-conductive elements that act together to reduce peak-valley style noise. The design utilizes two attenuating layers: one for the high frequency band (150kHz-2MHz) and another for emissions suppression. It is packaged in a hermetic mold with standards compliant pinouts.

The SBSGP5000153MXR EMI/RFI Filter is also very efficient at reducing noise. It features a differential mode inductance of 1.38nH and an attenuation level of -49 dB (typically -50 dB). The filter also has a low insertion loss of 0.1dB in the frequency range of 9-250MHz. It also features ESD clamping capability up to 6KV, which helps to protect against high-voltage spikes.

The filter’s working principle is based on the concepts of inductance and resonance. To effectively remove noise, it utilizes both inductive and capacitive elements to create resonant frequencies, which in turn attenuate the noise signal. The inductor absorbs the high-frequency noise, while the capacitors convert it to a lower frequency and release it harmlessly. By using the inductors and capacitors in combination, the filter is able to effectively eliminate both conducted and radiated emissions and finally reduce noise.

The SBSGP5000153MXR is an ideal EMI/RFI filter for a wide range of applications. It can effectively reduce conducted and radiated noise and provide an effective way to protect against ESD spikes. Its small size and hermetic package make it a great choice for a variety of applications, while its high attenuation level and low insertion loss make it a great choice for use with high-frequency circuits. The combination of inductors and capacitors makes it an excellent choice for reducing peak-valley style noise while providing efficient protection.
