Flat wire inductors can be classified into various types based on their functions, structures, and application scenarios, and exhibit some unique characteristics. The following is a detailed summary of the classification and characteristics of flat wire inductors:

classification

Classified by function:

Common mode inductor: commonly used in filtering circuits to reduce electromagnetic interference. Especially SQ flat wire common mode inductors, as a substitute for magnetic ring common mode inductors, have the advantages of high utilization of winding space, small inter turn parasitic capacitance, and good EMI effect.

Differential mode inductor: Corresponding to common mode inductor, used for processing differential mode signals. Flat wire differential mode inductors have better overcurrent and heat dissipation capabilities due to the use of flat wire winding.

Power inductor: commonly used in power management circuits for storing and releasing energy. Flat wire power inductors have higher current carrying capacity and are suitable for high-power applications.

Classified by structure:

Single layer coil: The coil is wound on a flat surface, with a simple structure but relatively small inductance.

Multilayer coil: The coil is wound on multiple planes, which can increase inductance, but the structure is relatively complex.

Honeycomb coil: When the coil is wound, it forms a structure similar to a honeycomb, with the advantages of small volume, small distributed capacitance, and large inductance.

Classified by application scenario:

In mobile communication devices such as smartphones and tablets, flat wire inductors are commonly used for filtering, decoupling, and other circuits.

Computers and consumer electronics: used in devices such as computer motherboards, graphics cards, routers, etc. for power management, signal filtering, etc.

Automotive electronics: In automotive electronic systems, flat wire inductors are used for power filtering, signal transmission, etc.

Industrial control: Used in industrial control equipment for power filtering, signal conditioning, etc.

Medical equipment: In medical equipment, flat wire inductors are also used for power filtering, signal transmission, etc.

characteristic

High efficiency: Flat wire inductors have low direct current resistance (DCR), which can reduce power loss and improve the overall efficiency of the circuit.

High current carrying capacity: Due to the flat wire design, inductors can withstand large currents, meeting the needs of high-power applications.

Good heat dissipation performance: The flat coil design helps improve heat dissipation efficiency, reduce the temperature of the inductor during operation, and thus improve the reliability of the circuit.

Miniaturization and easy layout: The flat coil design makes the inductor smaller in size, making it easier to use in electronic devices with limited space. Meanwhile, the flat coil design makes the layout of inductors on the circuit board more flexible, which helps to improve the overall performance of the circuit.

Low cost: Flat wire inductors can be machine wound, with good consistency, easy to make into standard parts, can be centrally purchased, high production efficiency, short delivery time, and low cost.

In summary, flat wire inductors have various classifications and significant characteristics, which make them play an increasingly important role in modern electronic devices.
