Mentech Magnetic Product Line

In electronic circuits, controlling the flow of current is essential for stability, efficiency, and device protection. At Mentech, we focus on designing and producing high-quality inductors that influence current behavior in precise ways, ensuring reliable performance across a variety of applications. Our extensive experience as a professional transformer and inductor manufacturer allows us to develop components suitable for power modules, communication systems, automotive-grade electronics, and optical storage devices. Understanding how does an inductor affect current is key to optimizing circuit performance and selecting the right magnetic component for each application.

Limiting Sudden Changes in Current

An inductor resists changes in current due to its property of self-inductance. When current attempts to rise or fall rapidly, the inductor generates a counter electromotive force (EMF) to oppose the change. This behavior ensures smoother current flow and protects sensitive components from voltage spikes. At Mentech, our PFC inductors, common-mode and differential-mode inductors, and high-performance integrated power inductors are engineered to provide consistent current regulation. Compared with circuits without inductors, those incorporating Mentech inductors experience reduced current fluctuations, which is especially important for high-performance digital switches, Ethernet switches, and smart home networking equipment.

Storing and Releasing Energy

Inductors store energy in their magnetic field when current flows through the coil, releasing it when the current decreases. This energy storage property allows the inductor to maintain a more constant current over time, effectively acting as a buffer in electronic circuits. Mentech’s high-power wound inductors, planar transformers, and filter inductors are designed to maximize this effect, ensuring that automotive-grade devices, OBC transformers, DC-DC transformers, and drive transformers operate reliably under variable load conditions. Compared with resistors or capacitors, inductors uniquely manage current in a way that smooths variations while conserving energy, which is critical in both new energy and communication applications.

Reducing Electromagnetic Interference (EMI)

By regulating current and opposing sudden changes, inductors also play a vital role in reducing electromagnetic interference. Stable current flow minimizes high-frequency noise, protecting devices such as ADSL, EOC, VDSL, and LED controllers from disruptions. Mentech’s common-mode and differential-mode inductors are specifically designed to filter EMI, creating a clean and stable electrical environment. When comparing circuits with and without inductors, the difference is clear: circuits with Mentech inductors experience significantly lower noise levels, ensuring more reliable performance across integrated business digital devices, POE-powered devices, and FILT optical loop equipment.
