Effectiveness of a Triaxial Cable Using Pigtails to Terminate the Outer Shield to Chassis Versus a Coaxial Cable With the Shield
Introduction Although it should be well known that the shielding effectiveness of a cable is severely compromised when it is terminated to ground with pigtail/s many equipment manufacturers still use this technique. We see in Reference 1 Figure 7.66 and Table 7.4, Figure 7.80, and Figure 7.102 that the shielding effectiveness of a coaxial cable with pigtail terminations may … [Read more...]
Doing Things That Usually Do Not Work
“If you’re not making mistakes, then you’re not doing anything.” — John Wooden Over the years, I have seen several things that make me scratch my head. Many of them are things I have done (there, I admitted it). I would like to look at these situations to (maybe) help not to make the same mistakes. So, to be clear: Do not do these things. Concerning Shielding One would … [Read more...]
FN3280H Filter Series with “R69” Option
Schaffner is pleased to announce the release of a complete range of our popular 4-Line filter series: FN3280H with higher insulation resistances. The new line-up of FN3280H filters with the so-called R69 option will not cause the overall insulation resistance of the machinery equipment under test to drop below 1 MOhm allowing the system fitted with an EMC filter to comply … [Read more...]
Seven Fundamental Considerations for Selecting EMI Filters
By Rigoberto Rios, Jorge Varela, and Amanda Ison Virtually every electronic device is subject to and, to at least some degree, must be protected from electromagnetic interference (EMI), or electrical noise. EMI is generated by both naturally occurring and engineered sources ranging from solar flares to cell phones, and, if left unmitigated, diminishes the integrity and … [Read more...]
