Transformers, especially in high-frequency applications, can act like miniature antennas—emitting or picking up unwanted electromagnetic interference (EMI) that disrupts surrounding systems. This interference isn’t just theoretical; it’s a real threat in industries where reliability is non-negotiable—like medical devices, industrial automation, and smart metering.

In my years of working in the transformer and magnetic components industry, I’ve seen just how common and frustrating electromagnetic interference, or EMI, can be. It creeps into modern electronic systems from switching power supplies, wireless signals, and long cables, causing instability, noise, and even system failure.

Have you ever wondered what makes high-frequency transformers so vital in modern technology? From powering renewable energy systems to driving industrial control mechanisms, these transformers are the backbone of countless applications. But there’s a critical yet often overlooked detail in their design—the use of sleeves on winding wires.
