Modular Connectors – Jacks With Magnetics are a type of connector which uses magnets in order to create an electrical connection between two components or systems. The J0033D21 is a perfect example, boasting a range of impressive features and applications. The article below will provide an in-depth look into the J0033D21, exploring the various uses of this connector and the working principle behind it.

Features & Applications

The J0033D21 is a PCB-mount, shielded, mini-magnetics connector with a 3.5mm profile. The gold-plated contacts of the J0033D21 provide excellent electrical performance with a low insertion loss. This connector also has a low profile of only 3.5mm, making it ideal for applications where space is at a premium. Additionally, it is RoHS compliant and features a high surge current of up to 100 Amps. With these features in mind, the J0033D21 is most ideal for applications within the communications and networking industry.

This connector is most commonly used in Subscriber Line Interface Circuits (SLICs). SLICs are integrated circuits which bridge the gap between telecommunications systems and the customer’s device, such as a telephone or ADSL modem. The J0033D21 can also be used in LAN devices, as it is capable of providing a reliable connection between multiple devices over a LAN. Similarly, it is also suitable for use in short-haul, long-haul, and ultra-long-haul applications which require a small form factor. Lastly, this connector is also found in set-top boxes, gaming consoles, backplanes, as well as various other types of electronic equipment.

Working Principle

The concept behind the design of the J0033D21 revolves around magnetics. Magnetics are materials which contain atoms with unpaired electrons, which makes them naturally magnetic. These magnets are then utilized in the connector to induce an electric field. This electric field then creates an electromotive force, allowing current to pass through the connector without any resistance or interference.

The J0033D21 utilizes a hybrid construction of magnetics and normal copper cabling in order to ensure better performance. This hybrid construction reduces the amount of crosstalk and minimizes the amount of power which is lost as current travels through the cable. Additionally, this hybrid construction also offers EMI protection and reduces sensitivity to vibration, making it a much more reliable connection than comparable cables.

Conclusion

The J0033D21 is a perfect example of modern modular connectors which utilize magnetics as a method of creating an electrical connection. This connector is ideal for applications within the communications and networking industry, as it offers low insertion loss and excellent electrical performance. Additionally, the hybrid construction of the connector reduces crosstalk, minimizes power loss, and provides an EMI protected connection. With its wide range of impressive features and applications, the J0033D21 is an ideal choice for any electronics engineer or technician in need of a reliable connection.
