C Core Inductors

Cut Core Inductors (C Core) are electromagnetic components designed to store energy in a magnetic field and regulate current in electronic circuits. They are made using cut core magnetic cores, constructed from laminated or solid magnetic materials, such as silicon steel or ferrite, that are precision cut into specific shapes. C Core Inductors are paired with wound wire coils to create inductors capable of handling high energy levels with reduced losses. These inductors are ideal for applications requiring many transformers in non-standard sizes.

C Core Inductor Advantages

Cut core inductors are an essential component in modern electronics, offering high efficiency, reliability, and versatility across a gamut of industries. C Core Inductors provide the following benefits:

  • Low Core Loss – Can be manufactured from advanced core material with low core loss. C Cores are similar to toroidal cores, offering lower core losses than conventional EI or EE cores.
  • High Flux Density – Can be built with material that can handle a high flux density.
  • Compact – Compact design can reduce volume or increase load capacity.

Applications for C Core Inductors

The cut core inductor’s advanced design enables precise energy regulation, making them ideal for applications ranging from power supplies to renewable energy systems. Whether it’s industrial equipment or sophisticated electronic devices, cut core inductors provide a critical solution for managing magnetic energy efficiently. Applications include:

  • Power Supplies - Transformers and filters in high-frequency switching power supplies.
  • Renewable Energy Systems - Energy storage in solar inverters and wind power converters.
  • Industrial Equipment – Motor drives, welding equipment, and industrial transformers.
  • Telecommunications – Networking equipment signal conditioning and voltage regulation.
  • Aerospace and Automotive – Power regulation in electric vehicles and avionics systems.
