Introduction:

The ARJM11D7-116-JJ-EW2 is a modular connector jack with built-in magnetics manufactured by TE Connectivity. These jacks are designed to provide superior EMI/RFI protection and wide frequency range of circuit isolation from 100KHz to 1GHz. The ARJM11D7-116-JJ-EW2 fits into a 5.08 mm pitch, which makes it a great choice for electronic applications that require physical size constraints.

Application Field:

The ARJM11D7-116-JJ-EW2 is widely used in industrial control, test and measurement device, digital TV, military and medical equipment, and other electronic applications. The device\'s low profile design makes it a preferred choice when space is a limiting factor. It is also certified for use in power sensitive and high-speed applications.

Features:

The ARJM11D7-116-JJ-EW2 offers great performance qualities that include shielding, high-frequency isolation, and low-interference operation. It features a double shield design to provide optimal protection against electromagnetic interference. The shielding is effective for both internal and external crosstalk, which translates to better performance and a higher level of safety when working with high-frequency applications.

Construction:

The ARJM11D7-116-JJ-EW2 is a multi-polar connector that consists of a steel shell, two dielectric pieces, and polarized contact fingers. The shell of the device is made of tin-plated steel, which provides solid protection against wear and corrosion. It also has a finger-resistant design to ensure safe handling.The two dielectric pieces make up the internal portion of the connector. The dielectric pieces contain the metalized films and provide a variety of impedances for EMI/RFI protection. The dielectric pieces also help to reduce the frequency ranges and optimize the return loss of the connector.

Working Principle:

The internal magnetics act as an EMI/RFI filter and are used to provide optimal circuit isolation between circuits. The magnetics are designed to offer a wide frequency range of operation with high EMI/RFI protection. The isolation is achieved by attenuating high frequency signals, which helps to reduce the interference and cross talk between connected electronics.The magnetics also offer additional protection against external and internal electrical crosstalk, helping to maintain consistent performance when exposed to a variety of interference sources. The steel shell of the device also plays a part in providing shielding from outside sources.

Conclusion:

The ARJM11D7-116-JJ-EW2 is a popular choice for electronic applications due to its superior EMI/RFI protection and wide operating range. Its small form factor makes it perfect for applications that require physical size constraints. Its wide range of features, including shielding, high-frequency isolation, and low-interference operation make it a great choice for any application.
