Our team of engineers can assist in developing the optimal solution for your application requirements.
With in-house design, simulation, prototyping, and validation testing across our global centers in the U.S., Europe, and Asia, we support your team in delivering optimized solutions—whether leveraging our standard product portfolio, modifying an existing design, or developing a fully customized power magnetics solution.

Inductors and Chokes

Whether your application requires small surface mount inductors, large through-hole components or high power chassis mounted busbar inductor assemblies, GCi can provide the perfect solutions.
Our expertise covers inductors for AC line filtering, Direct and Common mode filtering, POL energy storage and beyond with:
  • Thru-hole or SMD designs constructed on standard cores and bobbins, toroid designs, multicore and module designs to fully custom mechanical designs
  • Magnetic core materials options such as amorphous alloys, ferrites, iron powders, and laminations
  • Conductor materials such as magnetic wire, Litz wire, copper foil, and copper busbars
Our experienced engineers can work with you directly to understand your specific application needs and provide an optimized solution from our vast existing product design base or a completely custom design if required.
SMD power inductors are widely used in numerous power conversion topologies. From automobiles, consumer electronics to DC-DC converters, virtually every power conversion topology that regulates voltage uses an inductor. GCi offers inductors with small footprints, low profile, wide inductance ranges and shielding for minimizing conducted and radiated emissions.

You will find various versions that meet RoHS/Reach compliance and automotive AEC-Q200 validation requirements. Our products are designed for to achieve high power density, with low DCR and low core losses. Custom designs are possible as well to meet customer specific requirements.

Signal & Filtering Magnetics

In today’s modern electronic systems it is often necessary to block unwanted high-frequency noise (EMI) or separate specific signal bands from interference in order to ensuring signal integrity in telecommunications, power supplies, and data lines. Many applications also require safety isolation to prevent electric shocks, eliminate ground loops, suppress voltage spikes/surges, and protect sensitive devices.
GCi Technologies has designed and developed an extensive portfolio of solutions that address the needs for signal integrity, filtering and isolation in applications like:
  • BMS - Battery Management Systems
  • Data Communications – Ethernet/LAN, PoC & PoDL
