Shield DC Power Jack

A shielded DC Power Jack socket is a type of electrical connector designed to protect sensitive electronic circuitry from electromagnetic interference (EMI) and radio frequency interference (RFI). These jacks incorporate a metal housing or shield around the connector, effectively blocking external electromagnetic fields from disrupting the power flow and signal integrity.

Key Features of Shielded DC Power Jacks:

• Metal Housing or Shield: The most defining feature is the metal housing or shield that surrounds the connector. This shield acts as a barrier, preventing electromagnetic waves from penetrating and affecting the internal circuitry.

• EMI/RFI Protection: The shielding effectively reduces the impact of electromagnetic and radio frequency interference, ensuring a clean and reliable power connection. This is crucial for applications where noise sensitivity is a concern, such as audio/video equipment, medical devices, and industrial control systems.

• Various Center Pin Sizes: Shielded DC Power Connector jacks are available with different center pin diameters, such as 2.1mm, 2.5mm, and 3.5mm, to accommodate various power plugs.

• Current Ratings: The current rating indicates the maximum amount of current the connector can safely handle. This is an important factor to consider when choosing a connector for a particular application.

• Mounting Styles: Shielded DC power jacks can be found in various mounting styles, including panel mount, surface mount, and through-hole, to suit different design requirements.

DC Power Jack connectors are preferred in applications where electromagnetic interference (EMI) and radio frequency interference (RFI) can significantly impact the performance and reliability of electronic devices. Here are some specific applications where shielded DC power jacks are commonly used:

Typical Applications

• Audio and video equipment

• Industrial control panels

• Communication devices

• Medical and measurement instruments

• Embedded systems with analog components

These jacks are ideal for products that must meet EMC regulations or operate reliably in electrically noisy environments.

In addition to these specific applications, shielded DC power jacks are also used in a wide range of other applications where EMI/RFI protection is critical, such as security systems, home automation, and alternative energy systems.

The use of Shielded 5A PCB Mount DC Power Jacks is becoming increasingly important as electronic devices become more sensitive to electromagnetic interference and as the use of wireless technologies continues to grow. By incorporating shielded DC power jacks, manufacturers can ensure the reliable operation of their products in a variety of environments and applications.
