FLAT WIRE INDUCTOR

DESIGNED FOR EFFICIENCY!

Electronics devices are getting more efficient and smaller. Therefore it is important that electronic components are designed accordingly. To fulfil these requirements WE inductors are using optimized core materials and suitable wire shapes like flat wire. The WE-XHMA series features an extremely high current capability of up to 50.6 A saturation current and the ability to handle high current transient peaks. Its design with flat wire coil and a composite core material ensures low copper losses and stable behavior under temperature fluctuations.

Typical Buck converter application

Improve the efficiency by using a flat wire inductor

The Implications of the Skin Effect

The figure shows the cross section of acylindrical conductor and a flat conductor, the intensity of the grey color represents the intensity of the current in the conductor.δ is the skin depth.
The figure shows the cross section of acylindrical conductor and a flat conductor, the intensity of the grey color represents the intensity of the current in the conductor.δ is the skin depth.

The AC skin effect reduces the effective cross section area the current can flow. A flat wire has much more surface area with the same cross-sectional area. With more surface area, the impact of the skin effect is reduced.

Distribution of the electric field in flat and round wire

 Flat wire can distribute the electric field uniformly, which minimizes the parasitic capacitance and achieves the best EMC effect at the source. The EMI compatibility problem will be minimized.

The size difference between WE-XHMA and a conventional standard shielded power inductor

Using flat wire is space saving. For example the WE-XHMA is 3 times smaller in volume and requires 3 times less space on the PCB than an equivalent round wire inductor. When comparing 1:1 sizes, flat wire inductors offer better rated currents than an equivalent round wire inductors.
