M M The PCB Layout Decisions That Determine Whether Your Ethernet Port Passes EMC Testing I’ve seen the same EMC failure pattern enough times to describe it precisely: a hardware team does everything right on paper — correct…
M M Two Components, Two Jobs: Why Common Mode Chokes and Network Transformers Aren’t the Same Thing I’ve had the same conversation more than a few times with engineers who are new to Ethernet hardware: “Do I need a common mode choke if I…
M M SMD or THT Network Transformer? The Decision Is More Nuanced Than You Think Most engineers default to SMD for network transformers without much deliberation, and most of the time they’re right. But I’ve seen enough…
M M A Customer Burned a Standard Transformer in a PoE Design. Here’s What They Should Have Known. I get this question more often than I’d like: “We used a standard network transformer and the PoE link works fine in the lab, but fails…
