Flat Wire Inductor SPQ

Our High Current Flat Wire Inductors are engineered for applications that demand excellent current handling, low copper loss, and maximum power density. With optimized winding geometry and premium magnetic materials, these inductors deliver superior performance in modern high-efficiency power electronics.

Compared to traditional round-wire designs, flat-wire structures significantly reduce AC resistance and temperature rise, making them ideal for high-power DC-DC converters, automotive electronics, industrial drives, and fast-charging systems.

Whether you need a standard model or a Custom Flat Wire Inductor, FERRTX provides flexible design options tailored to your electrical and mechanical requirements — from inductance range to core structure, thermal limits, footprint, and SPQ packaging.

Why Choose FERRTX SPQ Power Inductors?

✔ High Current Capability

The enlarged surface area of flat copper windings minimizes skin effect, allowing the inductor to operate at higher RMS and peak currents with exceptional stability.

✔ Low DCR & Reduced Power Loss

Optimized winding paths greatly reduce resistance, lowering conduction loss and improving overall converter efficiency — especially in high-frequency applications.

✔ Compact, High-Density Structure

Flat-wire windings enable tighter assembly and better magnetic utilization, delivering high inductance in smaller form factors.

✔ Excellent Thermal Performance

Uniform heat distribution, minimal hot-spots, and strong thermal dissipation support long-term reliability under continuous high-load conditions.

✔ Full Custom Support

We offer custom SPQ packaging, inductance tuning, core combinations, reinforced insulation, and mechanical modifications according to your system design.

Why Flat Wire Inductors Matter in Modern Power Electronics

As power modules become smaller and more efficient, traditional round-wire inductors often hit physical limitations in current density and temperature. Flat-wire technology solves this pain point by:

• Providing significantly lower AC losses at high frequencies

• Allowing higher saturation current with improved cooling

• Enabling more compact high-value inductors

• Enhancing mechanical robustness for automotive/industrial reliability

This makes flat-wire structures a must-have component in next-generation power architectures.
