Common mode chokes, such as the CMJ-4-472, are electrical components used to block the flow of common-mode currents in a circuit. Common mode currents are those which pass through both the hot and neutral wires in an alternating current system, and, depending on the application, can cause problems ranging from interference with other electronic devices to sparking and burns. The CMJ-4-472 is capable of blocking such currents up to a frequency of 10 kHz, making it ideal for applications like medical device testing, radio frequency communication, and microprocessor-controlled circuits.

The CMJ-4-472 is a dual-coil inductor that gets its performance from the magnetic properties of its core material and the way in which it is wound. The core material affects the choke\'s inductance, or the ability to store energy in a magnetic field and releases it when a fault, such as an unbalanced load or a surge in supply voltage, forces the current in the circuit to flow through the choke. In the CMJ-4-472, the core is wound with two coils; the primary coil is wound with a larger number of turns, allowing it to limit the amount of current that will flow through the choke at a given frequency. The secondary coil is wound with fewer turns to further limit the current for higher-frequency applications.

The design of the CMJ-4-472 also allows for it to be used in a variety of applications. As the choke is essentially a low-pass filter, it is able to block higher frequency signals from entering or leaving a circuit. This makes it ideal for use in radio frequency communication, as it helps to protect the equipment from potentially damaging electromagnetic fields. Additionally, the choke can be used to prevent interference between two electrical devices. The choke can beplaced between the two devices to block signals that could interfere with each other.

The CMJ-4-472 is also well-suited for medical device testing, as it can help isolate and protect sensitive test equipment from the higher-frequency signals emitted by electronic medical devices. As testing of such devices requires accuracy and precision, the CMJ-4-472 is capable of suppressing electrical noise that could interfere with the test process. In addition, the choke can be used to filter and protect signals in microprocessor-controlled circuits. By blocking noise that can interfere with the microprocessor, the CMJ-4-472 can help reduce the chances of errors or malfunctions in the circuit.

The CMJ-4-472 is a versatile common mode choke that can be used to block common-mode currents in a variety of applications. Its dual-coil design and magnetic core allow it to block frequencies up to 10 kHz, making it ideal for radio frequency communication, medical device testing, and microprocessor-controlled circuits. Its ability to isolate and protect sensitive electronic components makes it a valuable asset in any circuit design.
