As the complexity of modern electronics continues to increase, so do the requirements placed on DC/DC converters and the inductors used in them. High currents, limited installation space, demanding thermal conditions, and ever higher switching frequencies call for components that combine efficiency, reliability, and compact design. This is exactly where the WE‑MXGI series from Würth Elektronik comes in. These molded, magnetically shielded SMD inductors were developed for modern DC/DC converter designs and combine an iron-alloy core material with an optimized winding geometry. The result is low DC and AC losses, stable electrical characteristics, and reliable operation across a wide operating range.

A key advantage of the series is its support for high switching frequencies above 1 MHz. This allows passive components to be designed smaller and enables more compact power designs. At the same time, the low-loss design helps limit temperature rise and improve efficiency even at high load currents. With saturation currents of up to 28 A, inductance values from 0.16 µH to 10 µH, and SMT package sizes 4020 and 5030, the series offers a high degree of flexibility for different requirements. Designers can therefore make targeted trade-offs between transient response, ripple current, efficiency, and PCB area without fundamentally changing the overall layout.

The WE‑MXGI series also offers advantages in terms of EMC performance. Its magnetically shielded construction reduces stray fields and facilitates use on densely populated PCBs. In addition, the molded design provides high mechanical stability, which is particularly important under vibration, thermal cycling, and assembly-related stress. The specified operating temperature range of –40 °C to +125 °C further expands the range of applications. Typical use cases include point-of-load converters, FPGA and processor power supplies, mainboards, graphics cards, mobile devices, wireless communication equipment, as well as industrial and embedded systems.

Overall, the WE‑MXGI series is not a single solution for every scenario, but a versatile building block within a broader inductor portfolio. For developers, this means greater flexibility in the design of compact, efficient, and thermally optimized power supplies.

The WE‑MXGI series is part of Würth Elektronik’s comprehensive inductor portfolio and is suitable for a broad range of applications. This gives developers additional flexibility when designing compact, efficient, and thermally optimized power supply solutions.
