Large flat wire inductor for electrical equipment and energy storage

What are high current flat wire inductors?

High current flat wire inductors are magnetically shielded inductors with exceptionally low DC resistance, designed for greater efficiency and high current ratings. Coilcraft offers these inductors for various applications.

What are ERU inductors?

ERU inductors are high current flat wire inductors with compact dimensions, low RDC, and high saturation currents. They feature a flat helical winding with a rectangular wire and can be used at high temperatures up to 150 °C. The components are magnetically shielded and designed in a self-leaded construction with underbody termination (SMD).

What is a compact flat wire inductor?

A compact flat wire inductor is designed for efficiency. Flat wire has a high winding factor of 95 %, so only 5 % is unused space in the gap between each winding compared to 30 % unused space in round wire. Figure 2 illustrates the space savings achieved by the high winding factor with minimal wasted space in the flat wire cross-section.

Can a flat inductor wire improve current conduction at high frequencies?

Bourns has found that altering the shape of the inductor wire from round to flat allows for more efficient current conduction at high frequencies.

What are the benefits of Bourns' flat wire inductors?

Bourns' flat wire inductors provide an optimal solution for designs that require high frequencies and high current. These inductors have powdered iron cores directly molded to the wire and are available in a vast range of inductance values.

Why is a round wire important in a high frequency inductor?

In high frequency inductor designs, round wire conductors are typically used. This is because the conductor is subject to the 'skin effect' at high frequencies, where electrons travel along the surface area of the conductor rather than through the entire cross section. Thus, having an efficient wire is essential in high power and high frequency designs.
