ARJM11D7-516-NN-EW4

Modular Connectors – Jacks With Magnetics

The ARJM11D7-516-NN-EW4 is a modular connector incorporating a magnetics feature. Developed by Samtec, this modular connector is a component device used mainly in telecommunication applications. By integrating magnetics, the connector provides galvanic isolation from the system power plane up to 1500Vrms, which is critical for data applications.

Application Field

The ARJM11D7-516-NN-EW4 is typically used for portable, embedded and telecom applications. It is suitable for cell phones, smart phones and tablet and eBook PCs. More specifically, this device is appropriate for audio and video applications, test & measurement, PON & Ethernet, and I/O applications. It is also suitable for CCTV and HDTV transmitters and receivers, gigabit Ethernet switches, and media converters.

Working Principle

The working principle of modular connectors is based on two parts. The first part is called a jack, and it is typically a female connector. It houses the electrical contacts for receiving the plug, which is the second part. The plug is typically a male connector that contains the signal line contacts. When the plug is inserted into the jack, the electrical connection is completed and current flows between the two parts.

The ARJM11D7-516-NN-EW4 has a built-in magnetics feature. This allows the device to reduce individual line reflections and crosstalk interference while improving signal integrity. As a result, this device provides high-speed data transfer in networking and communication applications.

Design

The ARJM11D7-516-NN-EW4 is comprised of many components including contacts, insulation and strain relief. The device is designed for high speed data transfer with a contact plating of gold for low contact resistance and durability. It has a temperature rating of -20°C to +105°C and an insulation resistance of 1000M ohms minimum. The polarization in this connector ensures proper mating and reduces common EMI/RFI problems.

Additional features of the ARJM11D7-516-NN-EW4 include an operational frequency of up to 400MHz, with a frequency dependence of 0.4dB or less. The device is RoHS compliant and can be purchased either with or without the magnetics feature. The standard package includes a front mount and two mounting screws for secure attachment.

Conclusion

The ARJM11D7-516-NN-EW4 is a modular connector designed specifically for telecommunication applications. It combines modular connectors with a built-in magnetics feature to provide galvanic isolation from system power planes. Suitable for portable, embedded and telecom applications, this device provides high speed data transmission rates and EMI/RFI reduction. With features such as a frequency rating of up to 400MHz and a temperature rating of -20°C to +105°C, the ARJM11D7-516-NN-EW4 provides a reliable connection for data and control applications.
