MEA1608LD150TA0G

Electromagnetic interference (EMI)/ Radio Frequency Interference (RFI) filters are components comprising of an arrangement of inductors, capacitors, and resistors designed to passively filter out certain frequencies of EMI or RFI.  This includes components such as MEA1608LD150TA0G which falls under this classification.  Specifically, MEA1608LD150TA0G is an industrial terminal block style EMI-RFI filter with 2-stage electrical frequency feature filtering.  It is typically used with several single-ended or balanced applications: monitors, audio, networking, and other applications that may be prone to EMI/RFI interference. 

As an electrical filter, the principle working of MEA1608LD150TA0G quite simple: low-pass filters are used to eliminate unwanted frequency components from the signal while keeping the steady-states intact. In this particular use, the low-pass filter component is the inductor coil that acts like a “short cable” for the signal, meaning that it will allow lower-frequency signals to pass through the filter while blocking higher frequency signals.   This ensures that undesired higher frequencies are attenuated, while the lower frequency signals are allowed to pass.   

This filter has two stages as part of its operation that act to better reduce and eliminate EMI/RFI interference.   The first stage, the inductive filter, works with the previously discussed principle, while the second stage, the capacitive filter, works in a slightly different manner.   The capacitive filter works by attempting to match its low frequency impedance to the source impedance.  This way, it prevents any signal reflections from going back to the source.  Both of these stages work together to reduce interferences by presenting a low impedance path for transmission signals and reflecting all unwanted interferences.  This is a fairly effective method when it comes to filtering out undesired signals. 

Overall, MEA1608LD150TA0G is specifically designed to filter out EMI/RFI interferences in a variety of single-ended or balanced applications such as networking and audio.  Its two-stage filter method of operation is exceptionally effective, making it an ideal choice for such applications.  The simple yet effective design of this filter, from capacitors to inductors, works together to properly attenuate undesired signals while allowing desired signals to pass.
