Common mode chokes are indispensable components in various industrial and consumer electronic applications. The RN242-1.4-02 is an example of such a device. This particular product is designed to provide high-frequency filtering for a variety of signal and noise sources.

The RN242-1.4-02 is a common-mode filter consisting of two bobbins wound with wire separated by two ferrite beads. This design allows the filter to provide high-impedance choking of common-mode signals, while permitting differential pairing or ringing of the transmission line without restriction. It also has a low attenuation at high frequencies through the use of low-loss sorbothane material between the filter and the magnetics.

The RN242-1.4-02 is typically used in industrial applications such as computers, networks, medical devices, test and measurement equipment, and consumer electronics. It is designed to provide maximum attenuation in the frequency range of 10 kHz to 1 GHz, making it suitable for a wide variety of applications. The device has a high impedance of 500 ohms at 1 MHz, and a low impedance of 200 ohms at 1 GHz, preventing common-mode noise from entering the system.

The RN242-1.4-02 is designed to operate in normal or reverse polarity. The two ferrite beads act as inductors, while the wire winding provides additional inductance. When an electromagnetic field or voltage is applied across the two bobbin windings, the current flow is reduced or blocked. This reduces the radiative emissions, prevents unwanted switching, and reduces radio frequencies interference. It also helps to reduce heating caused by current flow in the windings.

The RN242-1.4-02 common-mode filter has a high degree of temperature stability, with a maximum operating temperature of 85°C. It is rated for a maximum current of 2.2 A, and a rated impedance of 1 kΩ. The dimensions are 4.13 mm x 1.3 mm x 1.2 mm. The device is RoHS compliant and has a low profile, making it suitable for use in a wide range of applications.

In summary, the RN242-1.4-02 is a common-mode filter designed for industrial and consumer applications. It provides high-frequency filtering to reduce common-mode signals and noise sources, as well as reduce electromagnetic interference and radio frequencies interference. It is temperature stable, has an RoHS compliant low profile design, and has a high impedance at low frequencies and low impedance at high frequencies. The RN242-1.4-02 is an excellent choice for any industrial or consumer application requiring high-frequency filtering, and its unique design offers superior performance in a variety of applications.
