Common Mode Chokes are powerful components used to block out disruptive Electromagnetic contributions, while allowing signals to flow freely. One of the most powerful types of Common Mode Chokes is the CMT-8117, which provides outstanding performance at very low frequencies. This article will provide a detailed overview of the CMT-8117’s application field and working principle.

The CMT-8117 is a two-terminal common mode choke specifically designed to reduce spurious responses between 1MHz and 10MHz. It helps isolate the signal current from unwanted interference from other components, ensuring that only the original signal is passed. The CMT-8117 is a very effective RF isolation solution, and it can be used in a wide range of applications.

The primary application fields for the CMT-8117 are:

• The CMT-8117 is used in filtering circuits for noise suppression and signal enhancement. It can be used to reduce the impact of electrical noise on a circuit, as well as to increase the signal to noise ratio. It can also be used to help prevent interference between multiple systems on the same bus.

• The CMT-8117 is used to minimize crosstalk between various communication systems. By absorbing crosstalk from external sources, it helps reduce errors in data transmission.

• The CMT-8117 is also used for analog to digital connections. By providing immunity to external electromagnetic fields, it helps reduce the effects of jittering and other problems associated with mixed-signal systems.

The architecture of the CMT-8117 is designed to offer a high level of protection against common-mode noise. The choke is made from two metal cores surrounded by an electrostatic shield. The core is connected to the two external conductors, which is what allows it to offer proper RF isolation. The two cores are designed to affect the common-mode noise differently depending on frequency. The cores are also wired in such a way that they cancel out any interference due to the external magnetic field.

The CMT-8117 features an inductance of 4.2µH to 10µH over the entire frequency range, which offers excellent noise rejection. The direct current blocking ability is 2A-4A, and the leakage current is less than 0.1mA. The operating temperature range of the CMT-8117 is -35°C to +125°C.

The CMT-8117 offers excellent performance in a wide range of applications. It is designed to provide high-level RF isolation, and it is highly reliable. In addition, it is easy to install, and it is relatively inexpensive. The CMT-8117 is an ideal solution for applications where common-mode noise reduction is critical.
