EMI/RFI Filters (LC, RC Networks) are a type of electronic filter that is used to limit the effects of radio frequency interference (RFI) and electromagnetic interference (EMI). They are often used in a variety of applications and for different types of equipment, including computers, medical devices, automotive systems, and even military hardware.The most common type of EMI/RFI filter is the LC (low-pass) network, which is made up of coils and capacitors to form an AC impedance that acts as a low-pass filter, meaning that only low frequencies will be passed through while high frequencies are blocked. RC (high-pass) networks are also used to provide high-frequency blocking, and both types of filters are often used in conjunction to create wider frequency bands of suppression.One example of an application of the EMI/RFI filter is the MEM2012D501R, which is a single-stage filter designed for power supplies and other sensitive electronic components. This device has a ceramic substrate and is rated up to 125VAC and rated for currents up to 4A. It is made up of a series of capacitor-resistor-inductor (CRL) networks in order to provide EMI and RFI attenuation.The working principle of the MEM2012D501R involves several steps that culminate in the attenuation of EMI and RFI. The first step is the shielding, which involves surrounding the circuits with metal fixtures that act as a Faraday cage to block out external radio waves. Next, the capacitors and inductors form a network, which passes the current through a series of changing paths to reduce the noise. Finally, the resistor helps to reduce the impedance mismatch between the circuits, which minimizes the reflection of any noise that has been generated in the circuits.When used correctly, the MEM2012D501R can provide excellent protection against both EMI and RFI. The metal shielding helps to block out any external radio waves, while the CRL networks and resistor minimize reflection and impedance problems. By forming the right combination of components, the amount of interference can be reduced significantly, which will ultimately ensure that any sensitive electronic components are properly protected from potential damage.
