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...

Why Core Selection Starts with the Right Ferrite Material A switching power supply running at 200 kHz doesn't need the same core material as a common-mode choke operating at 10 MHz. Picking the wrong...

Why Engineers Keep Choosing Mn-Zn High Conductivity Ferrite Switched-mode power supplies run hotter, faster, and smaller than they did a decade ago — and the magnetic core sitting at the heart of eve...

Power electronics engineers face a recurring dilemma: how do you push switching frequencies higher while keeping core losses under control? The answer, for most designs operating below 5 MHz, is the ...

Every time a laptop charges, an EV battery absorbs power, or a solar inverter converts DC to AC, a soft magnetic ferrite core is working somewhere in that circuit. These ceramic components are rarely...

A ferrite core sitting in a switching power supply handles hundreds of thousands of magnetic reversals every second. That relentless cycling is exactly why material selection matters — the wrong core...

What Makes Mn-Zn Power Ferrite the Go-To Core Material for Power Electronics Pick up any switching power supply, EV onboard charger, or solar inverter — there's a good chance its transformer core is ...

Manganese-zinc (Mn-Zn) ferrite is one of the most widely deployed soft magnetic materials in modern power electronics — found in everything from EV onboard chargers to 5G base station transformers. I...

Superior High-Frequency Performance Defines Soft Magnetic Ferrites Compared to conventional magnetic materials like silicon steel or amorphous alloys, soft magnetic ferrites exhibit extremely high el...
