The 51-359-001 EMI/RFI filter is a single-stage device designed to attenuate electromagnetic interference (EMI) or radio frequency interference (RFI) signals from a variety of electrical and electronic systems. By suppressing or eliminating these unwanted signals, the filter ensures that the system’s sensitive components are not damaged or malfunctioned from overloading. It also helps prevent disruption of adjacent electrical and electronic equipment.

The 51-359-001 filter significantly reduces EMI/RFI signals from passing through the filter by using a combination of a coil and capacitor. The coil is typically made of flat or round wire and is wound around a ferrite or other magnetic material. The coil acts as a choke, blocking out any alternating current and effectively stopping the electromagnetic noise or RFI from passing through. The capacitor is connected to the coil at both ends and acts as a frequency selector, allowing only the desired frequencies to pass while blocking out those outside the range. The combination of these two components creates an LC ( inductor and capacitor) network that can filter out unwanted frequencies.

The 51-359-001 filter can be applied to a variety of applications, from home consumer electronics to industrial systems and military electronics. It is commonly used to protect sensitive components, such as microprocessors, sensors, and transistors, from damage caused by excessive EMI/RFI. This filter also helps prevent disruption of other electronic equipment, like computers, TV, cell phones, and radios, by reducing the amount of interference.

The 51-359-001 filter also features RC (resistor and capacitor) networks which are used to reduce EMI/RFI signals that are either too low or too high in frequency. These RC networks consist of a series of resistors and capacitors connected in parallel and arranged in a specific pattern. This arrangement allows only the desired frequencies to pass while blocking out frequencies outside the range. This type of filter is very effective in reducing or eliminating EMI/RFI signals from passing through the filter.

The 51-359-001 filter is a great choice for attenuating EMI/RFI signals in various applications. It is easy to install and can be used in both on-board and stand-alone solutions. The combination of an LC and RC network makes it highly effective in suppressing unwanted frequencies, offering great protection for sensitive components and minimum disruption of other electronic equipment.
