Coil Inductors
Design and function of coil inductors
Coil inductors consist of a coil wound on a ferrite core or air core. This compact design enables efficient energy transfer and signal stabilization in electronic circuits. There are two main types: Whole Shield Type Inductors with complete shielding to reduce electromagnetic interference and No Shield (CD) Type Inductors, which are of open construction and are used for applications with low EMC requirements.
Thanks to SMD (Surface Mounted Device) technology, these inductors can be soldered directly onto the PCB, which saves space and facilitates automation in production. They are used in DC-DC converters, power supply units and high-frequency applications to ensure stable and interference-free signal transmission.

Further information about Coil Inductors
In the following frequently asked questions (FAQ), we answer the most important aspects of coil inductors - in a clear, practical and to-the-point manner. You will quickly find the right information for your application.
What are coil inductors and what are they used for?
Coil inductors are compact coils that are used in electronic circuits to stabilize signals and filter out interference. They consist of a wound copper wire coil on a ferrite or air core and are available as Whole Shield Type (with shield) or No Shield (CD Type, without shield).
These components play an important role in DC-DC converters, switching power supplies and high-frequency applications. Particularly in telecommunications, automotive technology and industrial electronics, they ensure reliable signal transmission and improved energy efficiency. Thanks to SMD (Surface Mounted Device) technology, they can be soldered directly onto the PCB, which facilitates their integration into modern, space-saving designs. Through its collaboration with Hongda Capacitors, Rotima AG offers high-performance coil inductors for a wide range of applications.

What are the differences between Whole Shield Type and No Shield (CD) Type inductors?
Coil inductors are available in two main variants: Whole Shield Type Inductors and No Shield (CD) Type Inductors. Whole Shield Type inductors are fully shielded to reduce electromagnetic interference and improve performance in sensitive circuits.
This design is particularly suitable for applications with stringent EMC requirements, such as high-frequency modules or wireless communication. No Shield (CD) type inductors, on the other hand, have no shielding and therefore offer lower inductance in a more compact design. They are ideal for applications that are less susceptible to interference and where space saving and low costs are paramount.
Both variants are suitable for DC-DC converters, power supply units and HF circuits, whereby the choice depends on the specific requirements of the respective application.

How do I find the right coil inductors for my application?
The selection of suitable coil inductors depends on several factors. Important are the required inductance (in µH), the maximum current, the resistance (DCR) and the saturation current limit. High frequency applications often require Whole Shield Type inductors to minimize electromagnetic interference.
For less critical applications, a no shield (CD) type inductor is often sufficient. Size also plays a role - the more compact the design, the more carefully the thermal load capacity must be checked. Manufacturers such as Hongda Capacitors offer a wide range of inductors that are specially optimized for different circuit requirements. With Rotima AG as a distributor, customers receive expert advice and the right components for their individual projects.

Why are coil inductors so important in DC-DC converters?
In DC-DC converters, coil inductors ensure efficient conversion and stabilization of the output voltage. They store energy in their magnetic field during the switching cycles and pass it on to the load in a targeted manner. This enables smooth voltage regulation and prevents voltage peaks that could damage sensitive circuits. Whole Shield Type inductors are preferred in demanding designs as they reduce electromagnetic interference (EMI).
No Shield (CD) type inductors are often used in space-critical applications with lower EMC requirements. Without a well-dimensioned inductor, a DC-DC converter would operate inefficiently and potentially generate unwanted signals. With the high-quality products from Hongda Capacitors, Rotima AG offers high-performance solutions for efficient energy conversion.

What role do coil inductors play in high-frequency technology?
In high-frequency applications, coil inductors are crucial for controlling signal flows and reducing interference. They are used in wireless communication modules, RF filters and antenna circuits. Whole shield type inductors in particular offer great advantages here, as they prevent interfering electromagnetic interference and maintain signal integrity.
In RF circuits, they enable precise tuning of frequency ranges and improve the overall performance of RF transmitters, receivers and amplifiers. No Shield (CD) type inductors, on the other hand, are used in less critical signal paths or in space-optimized designs. Companies looking for reliable high-frequency solutions benefit from Rotima AG's cooperation with Hongda Capacitors to obtain high-quality, high-performance inductors for their applications.
