Gaps In Return Planes – Bad News for EMI
Currently, there is an ongoing discussion among SI and EMC engineers on the fine points of PC board design for best signal integrity and EMI performance. Among the topics it seems designing in gaps or slits in ground return planes always comes up. Gaps can also occur mistakenly due to the addition of some connectors or other object that creates gaps in the copper. In fact, … [Read more...]
Robust Capacitors Suitable for EMI Suppression in Input Filters
TDK Corporation has a new series of robust EPCOS MKP X2 capacitors for EMI suppression. Compared with conventional X2 capacitors designed for rated voltages of 305V AC, these new components offer a higher rated voltage of 350VAC. This makes them suitable for EMI suppression in input filters – specifically for applications on the North American market – and output filters of … [Read more...]
