EMI/RFI filters are used to protect cabling and other parts of an electrical system from electromagnetic interference (EMI) and radio frequency interference (RFI). The SBSPP1000472MXR is an example of a filter used to attenuate unwanted signals and protect sensitive circuitry. The specifics of this filter’s application field and working principle are outlined in this article.

Application Field

The SBSPP1000472MXR is a two-element LRC or LC filter, designed for signal line and power circuit protection. It is intended to protect a system from EMI/RFI and provide a high degree of attenuation over a given frequency range. The SBSPP1000472MXR is particularly suited for protecting non-power line systems, such as personal computers or TVs, from EMI/RFI induced interruption or interference.

Working Principle

The SBSPP1000472MXR is a two element LC filter. The two LC circuits of the filter, denoted in the schematic form as L1 and C1, form a resonance circuit. As the incoming signal frequency and magnitude vary, the resonance characteristics of the filter change. The signals not within the specified frequency range are effectively attenuated according to the filter’s filter characteristic that is determined by the values of the two LC elements. The filter is most effective when the frequency of the incoming signals is in close proximity to the resonance frequency of the filter. This allows the filter to attenuate the signals and protect circuitry from receiving and transmitting undesired frequencies.

The SBSPP1000472MXR is designed to be used in a wide variety of applications, but is particularly well suited for applications where the requirement is to attenuate only a specific frequency range, such as from EMI/RFI signals. With the correct setup, the filter can reduce the magnitude of the interfering signal to a minimal level and maintain an acceptable level of signal integrity in the protected circuitry. This filter is able to provide a high level of attenuation, along with the ability to provide a high level of impedance (Zf) to keep the signal distortion at a minimum.

Conclusion

The SBSPP1000472MXR is an EMI/RFI filter designed to provide a high degree of signal attenuation over a specific frequency range, making it well suited for applications such as suppression of EMI/RFI from personal computers or TVs. The filter works by forming a two-element LC resonance circuit, the frequencies of which change depending on the magnitude and frequency of the incoming signals. The filter has a maximum impedance of Zf, which keeps the signal distortion to a minimum in the protected circuitry. For these reasons, the SBSPP1000472MXR is an attractive option for use in signal line and power circuit protection.
