High Q Conductive Coil Ferrite Bead Multilayer Chip Inductors 0402 0603 0805 1206 1-300mA Current 0.047-100uH Inductance
What is a Multilayer Inductor?
A multilayer inductor contains a first conductive coil pattern and a second conductive coil pattern which are arranged in two layers in the upper part of a multi-layered body and are connected electrically in a consecutive manner in series to 2 more conductive coil patterns disposed in the lower part of the multi-layered body and therefore forming a spiral coil.

Types of Multilayer Inductors
There are many different kinds of multilayer inductors and at aolittel we produce many of the most common types categorized by Case Size/Dimension, Maximum Rated Current, Nominal Inductance, DC Resistance, Packaging type and Tolerance. The parametric filters on our website can help refine your search results depending on the required specifications.
The most common sizes for DC Resistance are 100 mΩ, 300 mΩ and 500 mΩ. We also carry multilayer inductors with DC Resistance as high as 11.5 Ω. Nominal Inductance can be between 2 nH and 100 µH, with the most common multilayer inductors having a Nominal Inductance of 4.7 nH, 100 nH, 1 µH or 10 µH.
Applications for Multilayer Inductors
Multilayer Inductors can be used in mobile communication systems and applications that require noise suppression at high frequency and impedance matching. In high-frequency applications, multilayer inductors can be used in signal processing modules such as mobile phones, Bluetooth, WLANs and tuners.
Choosing the Right Multilayer Inductor
When you are looking for the right multilayer inductors, with the FutureElectronics.com parametric search, you can filter the results by various attributes: by Tolerance (± 30 %, ± 10 %, ± 5 %,…), Case Size/Dimension (0402, 0603, 0805,…) and Maximum Rated Current (up to 1.2 A) to name a few. You will be able to find the right multilayer inductor from several manufacturers that can be used as multilayer chip inductors, SMD (surface mount) inductors or for an electrical inductor
