Introduction

EMI/RFI filters, or LC, RC networks, are important electrical components for engineers in industrial, consumer and automotive electronics applications. They provide an effective way to protect sensitive circuits from electromagnetic interference and radio frequency interference. The SCIF-3112-002 EMI/RFI filter is one such component utilized in various applications. This article explores the SCIF-3112-002 in terms of its application field and working principle.

Application Field

The SCIF-3112-002 is specifically designed as an integrated multiplexer with an integrated filter. The filter is commonly used in applications such as analog to digital converters (ADC) and digital to analog converters (DAC). It can also be used in communication devices such as modems and Bluetooth applications, and also as input/output filters in these devices.The SCIF-3112-002 EMI/RFI filter has a wide range of applications due to its high level of integration, with single-ended inputs and outputs that have been integrated into the filter. It can be used in a variety of applications where a space saving solution is required. The filter can also be used to reduce the levels of EMI and RFI generated by the device, which helps to ensure optimal EMI/RFI performance.

Working Principle

The SCIF-3112-002 EMI/RFI filter is a low pass filter, meaning it passes signals with low frequency content while blocking signals with higher frequencies. This helps to protect sensitive electronics from EMI/RFI interference from external sources.The low pass filter is made up of two components: an inductor and a capacitor. Inductors are made up of conductors, typically metal or a coil of wire, that stores magnetic energy in a magnetic field. Capacitors store electrical energy between two conductive surfaces, one of which is typically a metal plate.When these two components are combined in a low pass filter, the inductor and capacitor both contribute towards the filtering process. When a signal is applied to the filter, the signals with higher frequency content are blocked while the signals with lower frequency content can pass through the filter.

Conclusion

The SCIF-3112-002 EMI/RFI filter is an important component for engineers in industrial, consumer and automotive applications. It offers a cost-effective solution for blocking EMI/RFI interference from external sources. The low pass filter is composed of an inductor and capacitor, which, when combined, block signals of higher frequencies while allowing signals of lower frequencies to pass through.
