SMD

The different designs of inductors - for example coils on toroidal cores or on shaped cores - each offer specific advantages in terms of saturation behavior, stray field, size and thermal load capacity. The choice of core material, such as ferrite, iron filings or composite materials, also has a decisive influence on the electrical properties, particularly at high frequencies or high currents.

A significant trend is the availability of all these inductors as SMD (Surface Mounted Devices) versions. These surface-mountable components enable automated, cost-efficient assembly and contribute to the miniaturization of circuits. SMD inductors are characterized by compact designs, good thermal coupling to the PCB and excellent EMC properties. They are available in a variety of sizes, power ranges and frequency characteristics and can be used flexibly in high-frequency or switched-mode power supply applications. Thanks to modern manufacturing techniques, SMD inductors today achieve a mechanical and electrical robustness comparable to wired versions. This makes them the preferred choice for modern electronic designs in industry, automotive and telecommunications.
