About Featured Expert: Coilcraft

Coilcraft are longtime global industry experts in the design and manufacture of inductors, transformers, chokes and other magnetic components for electronic systems. The company develops its products and engineering resources around the effects of frequency, bias current, temperature, core material and winding construction on component performance. This operating-condition focus is especially important within power conversion, where inductors, coupled inductors and transformers must simultaneously address energy storage, saturation, winding resistance, core loss, shielding and available board space.

Coilcraft offers a wide range of core materials, package constructions and electrical configurations so that component selection can be aligned with actual converter requirements rather than nominal ratings alone. Its measured performance data and online analysis tools further support that process. Engineers can compare inductance under bias, AC and DC losses, temperature rise and other operating characteristics within the intended circuit conditions, including compact and high-frequency systems where thermal and magnetic Coilcraft - Featured Expert Logo - Electronics Industry Monthly behavior are closely linked. The same engineering approach carries into isolation, current sensing and gate-drive applications. Coilcraft transformers and related components support energy transfer, impedance transformation and current measurement within power supplies, motor drives, industrial systems and switching architectures using MOSFET, IGBT, silicon-carbide and gallium-nitride devices.

At higher frequencies, Coilcraft’s RF and microwave magnetics support filtering, tuning, impedance matching, biasing and signal conversion where controlled parasitics and frequency response are central to the design. Its chip inductors, air-core and ceramic-core components, and broadband transformers are used across communications, instrumentation and wireless systems. EMI control is addressed within the same wider signal and power environment. Common-mode chokes, ferrite components and filtering devices are designed to suppress conducted noise while preserving the intended signal or power path.

Coilcraft also supports applications where qualification, traceability and environmental performance are as important as electrical characteristics. Automotive-qualified and high-reliability product families extend the company’s magnetic expertise into vehicle electronics, medical systems, aerospace and other demanding operating environments. Standard components are complemented by custom magnetic designs for specialized electrical, mechanical and packaging requirements.

Typical applications for Coilcraft technologies include power supplies, voltage regulators, automotive electronics, industrial controls, telecommunications, RF and microwave systems, data communications, medical devices and aerospace equipment.

Founded in 1945 and headquartered in Cary, Illinois, Coilcraft supports customers through engineering, manufacturing and technical resources across North America, Europe and Asia. To learn more about Coilcraft and its magnetic-component technologies, please click here.
