Common Mode Chokes (CMCs) have become a vital part of today’s electrical systems. They help to reduce the amount of unwanted Noise, Interference and Cross Talk that affects sensitive electronics and ensure that components function at their best. SRF2012A-181YA is one of the many CMCs in the market today, and it is used in a wide range of applications because of its size, ease of use and reliable performance.

The SRF2012A-181YA is a single-channel CMC that provides a high level of common-mode signal suppression. It is a low cost, wideband solution with an operating frequency range from 10 kHz to 500 MHz. It is an ideal choice for a wide range of applications such as automotive, computers, home entertainment systems, marine electronics, consumer electronics, and many other applications.

The SRF2012A-181YA CMC is designed to suppress common mode noise under extreme temperature and environment conditions. Its common-mode rejection ratio (CMRR) is up to -40 dBs across its frequency range, making it an ideal choice for applications that require a high level of signal integrity. The CMC has a maximum insertion loss of 1 dB and offers excellent return loss of less than -15 dBs. Its DC current rating is 2 A and its rated current is up to 1 A.

The SRF2012A-181YA CMC is designed to provide superior EMI suppression. It operates over its frequency range with a wideband noise reduction capability. This ensures that the EMI generated from unwanted signals such as ESD spikes, RF, and other high frequency signals is effectively attenuated. The CMC also has a high cutoff frequency of 15.3 dB at above 2 GHz. This ensures that EMI signals above this frequency can be effectively suppressed.

The SRF2012A-181YA CMC works on the principle of magnetic field induction. Its inductor core is made of a ferrite material, which provides excellent magnetic field absorption and suppression of high frequency signals. The CMC uses a two-coil structure, where one coil is connected to an external ground, and the other coil is connected to the signal path. The two coils create a strong electromagnetic field that suppresses common mode noise.

The SRF2012A-181YA CMC is a highly dependable EMI protection device that is designed to perform in extreme environments. It can withstand temperatures up to 125°C, and is highly resistant to vibration and shock. The CMC is also highly resistant to moisture, making it suitable for use in outdoor applications. Additionally, the CMC is RoHS compliant, making it an environmentally friendly choice for many applications.

The SRF2012A-181YA CMC is a reliable and cost-effective choice for a wide range of common mode noise suppression applications. Its wide operating frequency range, high common mode attenuation, and high cutoff frequency make it an ideal choice for applications where high levels of EMI suppression are needed. Its high reliability and resistance to vibration, shock, and moisture make it suitable for use in a wide range of industrial and consumer applications.
