Multilayer Surface Mount Inductors

Multilayer surface mount inductors are passive components (i.e. requiring an external power source) that consist of two conductive coil patterns in the upper part of a inductor. These coils connect with two similar coil patterns on a lower layer which store energy in the form of a magnetic field when an electrical current flows through them.


What are multilayer surface mount inductors used for?

Multilayer surface mount inductors are used in devices which operate at high frequencies such as mobile communication systems, cell phones, Bluetooth devices and tuners. Their multilayered format is great for suppressing noise and blocking signal reflections which can affect signal quality (reception) in communication devices.

They take up less space than wire-wound surface mount inductors, making them suitable for small devices as well as in crowded circuit boards.


Types of multilayer surface mount inductors

These products are available in many different forms.

When choosing multilayer surface mount inductors you should consider the requirements of your circuit and choose a model which corresponds to the required current flow, pressure tolerance and temperature that the inductor can handle. This will help you to pair the inductor with the right circuit.
