Surface Mount Device (SMD) multilayer inductors, also known as chip inductors or multilayer chip inductors, are a type of inductor designed for surface mount technology (SMT) applications. They are widely used in modern electronic devices due to their compact size, ease of assembly, and compatibility with automated manufacturing processes.

Here are the key features and characteristics of SMD multilayered inductors:

1. Construction: These inductors are constructed using multiple layers of conductive materials (usually copper) and dielectric materials (usually ceramic) stacked on top of each other to form a compact, multilayered structure.
2. Small Size: SMD multilayer inductors are very small and come in standardized package sizes, such as 0402, 0603, 0805, and 1206, which correspond to their dimensions in imperial units (0.04 x 0.02 inches, 0.06 x 0.03 inches, etc.). This small size is beneficial for miniaturization and high-density PCB designs.
3. Surface Mount Technology: These inductors are designed to be mounted directly onto the surface of the PCB using soldering techniques, eliminating the need for through-holes and making the assembly process more efficient.
4. Inductance Values: SMD multilayer inductors are available in a wide range of inductance values, from nanohenries (nH) to microhenries (μH), making them suitable for various applications, including signal filtering, power supply decoupling, and RF impedance matching.
5. High Self-Resonant Frequency: Due to their compact construction and small parasitic capacitance, SMD multilayer inductors typically exhibit high self-resonant frequencies, making them suitable for high-frequency applications.
6. Shielded Versions: Some SMD multilayer inductors come in shielded packages, which help to reduce electromagnetic interference (EMI) and crosstalk between adjacent components on the PCB.
7. Temperature Stability: Multilayer chip inductors often have good temperature stability, ensuring that their inductance values remain relatively constant over a wide temperature range.
8. High-Quality Factors (Q-Factors): SMD multilayer inductors can have relatively high-quality factors, which means they have low losses and good efficiency in transferring energy.

SMD multilayer inductors are commonly used in various electronic applications, including smartphones, tablets, laptops, wireless communication devices, automotive electronics, and industrial equipment. They provide an excellent solution for designers looking to achieve high performance and miniaturization in their electronic circuits. When selecting an SMD multilayer inductor, it is essential to consider the required inductance value, current handling capability, self-resonant frequency, and any specific environmental or performance requirements for the application.
