COILCRAFT

Power inductors, RF inductors, transformers and magnetic filters

About the manufacturer

Coilcraft is a US manufacturer of magnetic components founded in 1945. The company is widely known for high-quality inductors and chokes used in power conversion, RF circuits and wireless communication systems.

Its portfolio includes power inductors, high-frequency inductors, transformers, coupled magnetics and filters. In addition to a broad catalog range, Coilcraft also develops custom magnetic components tailored to specific electrical requirements.

Coilcraft products are widely used in switching converters and high-power-density designs where low winding resistance, current capability, controlled inductance and compact dimensions are important. The company also offers product families for automotive, medical, military and other high-reliability applications.

Applications

Coilcraft components are used in power and signal paths where predictable magnetic characteristics, high efficiency and stable operation over a broad load range are required.

• DC/DC converters – energy-storage inductors for buck, boost and other converter topologies.
• Switch-mode power supplies – current filtering and ripple reduction.
• Automotive electronics – converters and power rails in vehicle systems.
• RF and wireless communications – high-frequency inductors and impedance matching.
• Servers and telecommunications – high-power-density voltage regulation.
• Industrial electronics – filtering and stabilization of power rails.
• Battery-powered devices – high-efficiency low-loss converters.
