Derived from two Greek words: Solen (pipe) and Eidos (coil), the solenoid is a type of an electromagnetic device that converts electrical energy into mechanical energy. It is generally made by tightly wounding wires in a helix shape around a piece of metal. Whenever an electric current passes through it, a magnetic field is created.

Inductance L Not only magnetic materials possess a magnetic field, but every current carrying conductor also creates a magnetic field itself. Energy can be temporarily stored in the magnetic field. This effect is technically exploited in coils, consisting of one or more wire windings. The synonymous term “inductor” has become established.

EMC ferrites are based on Ni-Zn materials. This material has good quality factors (Q < 3) above approx. 20 MHz – i.e. trimmed for high losses. These originate in the core material and serve to absorb EMC interference. The inductance of these components is purposely kept low. Inductors however should show high quality factors, i.e. operate as loss-free as possible and buffer energy in the magnetic field. Also, they require stable inductance values over a wide frequency range. The distinction emphasized is reflected in the layout of the relevant manufacturer catalogue.

The development of PCB 3D printers is potentially linked with a number of topics and challenges that can be closely related to passive components. The question I asked myself about 3D PCB printing capabilities was also inhibited by the current shortage of certain passive components.

Engineers are under time and budget pressures to complete their tasks efficiently. Designing a power supply can be a daunting task, especially for those without much experience. One of the most critical components will be magnetic. For a basic non-isolated buck, boost, or SEPIC converters, the power storage inductor must be determined.
