MEM2012TC151 Filters

EMI/RFI Filters (LC, RC Networks) are useful in a variety of applications, and the MEM2012TC151 is no exception. The MEM2012TC151 is a common EMI/RFI filter, designed to address a wide range of noise suppression needs. In this article, we will discuss the various applications and working principles of this filter.

Applications

The MEM2012TC151 is a type of EMI/RFI filter designed for a particular application – suppressing electromagnetic and radio frequency interference (RFI) in high frequency circuits. It is widely used in power supply line filter circuits to reduce common mode noise present on the power line. This type of filter is also used in power entry module circuits to minimize the amount of noise entering the board. Additionally, it is commonly found in audio and radio systems, automotive electronics, and medical devices.

The MEM2012TC151 filter is also a popular choice for data connectivity applications. It is an excellent choice for Bluetooth, LAN, Wi-Fi, and serial communication applications. The MEM2012TC151 eliminates any RF interference and reduces the cross-talk between the communicating devices. It is also suitable for USB 2.0 applications, providing efficient power line filtering and data line noise protection.

Working Principle

The MEM2012TC151 is a two-pole type filter, which offers a high attenuation of Electromagnetic Interference (EMI), Radio Frequency Interference (RFI) and more specifically conducted interference. The filter is constructed of capacitors, coils and varistors, all placed in the correct combination for a wider range of application.

The working principle of the filter is quite simple, it snatches the electrical noise before it can reach any electronic equipment. The filter is composed of two inductors and two capacitors, placed in a specific configuration in order to achieve the desired noise reduction. The inductors form small coils of the same shape as the capacitors, but just a bit larger. The combination of inductors and capacitors blocks the passage of high frequencies while allowing the passage of low frequencies.

In addition to providing excellent EMI/RFI protection, the MEM2012TC151 can also provide a degree of safety protection, such as a 1500V surge rating. The filter can also achieve a high MTBF of 110K hours and an operating temperature range of -25°C to +85°C.

The MEM2012TC151 is a proven performer, with an impressive track record of performance in a wide range of applications. Its flexibility and ease of use, in combination with its high efficiency, make it a popular choice among professionals and hobbyists alike.
