Inductors are passive two-terminal electrical components that store energy in the form of magnetic energy when electric current flows through them. They are also commonly called coils, chokes, or reactors.

Although they can only store energy for a short period of time, the reliability of inductors, as well as their ability to prevent changes in current, make them ideal for a variety of applications such as:

• Sensors, especially as contactless sensors
• Tuning circuits
• Energy storage
• Transformers
• Filters
• Ferrite beads
• Relays

Inductors provide optimized high-frequency characteristics, and can also be connected to capacitors to form tuned circuits, which are often used in RF equipment.

No matter what your inductor needs are, DEX can test, source, and deliver a broad selection of surface mount chip inductors and components, including:

• Ferrite
• Automotive
• General Circuit
• Metal alloy
• Power line
• RF
• Variable

Ceramic or ferrite-core, potted or sealed in epoxy, DEX’s chip inductors are available in a range of specifications to meet your unique needs for saturation current, resistance, inductance, maximum current, frequency ratings, and more.
