EMI (electromagnetic interference) and RFI (radio frequency interference) filters are designed to minimize the disruption of devices and systems caused by externally sourced EMI and RFI. SBSPP1000470MCB devices are ideal for EMI/RFI filter applications with high voltage and current requirements. This article will discuss the application field and working principle of the SBSPP1000470MCB.
Application Field
The SBSPP1000470MCB EMI filter is designed for applications involving relatively high currents and voltages. It is suitable for switching power supplies, DC-DC converters, motor controllers, and other applications with medium to high power requirements. In addition, it is suitable for high speed data communications, networks, and switch-mode power supplies.
The SBSPP1000470MCB contains two high-current capacitors, one inductor, and two spark gaps. This combination of components provides superior noise suppression and EMI/RFI filtering capabilities. The device has a wide frequency range, from 300 kHz to 500 MHz, and can handle up to 15 A of DC current, making it suitable for applications with higher power requirements.
Working Principle
The SBSPP1000470MCB is designed using two types of filter circuits; an LC (inductor-capacitor) filter network and an RC (resistor-capacitor) filter network. The LC filter network consists of an inductor and capacitor placed in series and connected to the power supply. This filter serves to attenuate any high frequency signals that may be present. The RC filter network is then added to reduce the higher order harmonics generated by the LC filter network.
The second component of the filter is an air-spark gap with two terminals. When an EMI/RFI signal is present, the spark gap provides a low resistance path for the signal, thus minimizing its effect. The spark gap also serves as an additional filter to reduce any additional higher order harmonics and provide additional EMI/RFI noise suppression.
These two filter networks work together to provide the desired high voltage and current requirements of applications using the SBSPP1000470MCB while also providing superior EMI/RFI suppression. The combination of these two filter networks ensures that the device is able to reliably handle a wide range of frequencies and prevent any interference from disrupting the system.
Conclusion
The SBSPP1000470MCB is an ideal device for EMI/RFI filter applications with high voltage and current requirements. The device contains two high-current capacitors, an inductor, and two spark gaps, which work together to provide superior noise suppression and EMI/RFI filtering capabilities. The combination of the LC filter network and the RC filter network ensures that the device can reliably handle a wide range of frequencies and prevent any interference from disrupting the system.
