Many engineers start a switch-mode power supply design with the same question: which magnetic material should carry the transformer and inductor cores? For a 150 kHz LLC converter, a 60 W flyback, an...

A power electronics engineer designing a 100 kHz switch-mode power supply will almost always choose manganese-zinc ferrite for the transformer and output inductor cores. The material has been the ind...

Why Soft Magnetic Ferrites Are the Workhorse of High-Frequency Power During a 100 kHz dc-dc converter prototype test, the transformer core temperature rose 35 °C above ambient in less than ten minute...

What Is Mn-Zn Ferrite? A design engineer specifying a core for a 100 kHz flyback transformer usually starts with one material family: manganese‑zinc (Mn‑Zn) ferrite. It is a soft magnetic ceramic pro...

What Are Soft Magnetic Ferrites? You are designing a switching power supply and need a core material that can handle tens of kilohertz without overheating. Soft magnetic ferrites are the answer. Unli...

Every switched-mode power supply on the planet depends on a component that quietly manages kilowatts of energy while barely breaking a sweat. In the overwhelming majority of designs, that component is...

Why MnZn Ferrite Cores Excel in Power Applications For high-efficiency power conversion, the core material directly determines whether a design meets its thermal and size targets. MnZn ferrite cores ...

Core Material Advantages in High-Frequency Circuits Soft magnetic ferrites serve as the backbone of efficient power conversion and signal integrity in circuits operating from tens of kilohertz to se...

A switching power supply that ran cool on the bench started overheating after three months in the field. Same circuit, same winding count — just a different batch of magnetic cores. That single subst...
