Abstract: To understand how common-mode signals are created and then suppressed, you should first understand the interaction of shields and grounds in common cable configurations. The following ...

Spoiler summary: It only takes -60 dB of mode conversion to fail an EMC compliance test if this common signal gets out on unshielded twisted pair cables. If a common mode choke is used, as much as -20 ...

When identifying and controlling electromagnetic interference (EMI), discussion of common-mode and differentialmode interference will likely dominate. Differential-mode interference is a signal that ...

It's no longer sufficient to just perform static CMR tests on isolators. You have to look at the dynamic performance of optical, magnetic, capacitive, and RF implementations. Static common-mode ...

If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...

TDK has created a range of surface-mount high-current common-mode chokes. “Customers who prefer reflow soldering but need high-current common-mode chokes can now get an SMD solution,” according to the ...
