It is often necessary to add additional filter components to a DC/DC converter module to meet Class A or Class B EMC limits, and to build such an EMC filter, inductors from a range of different manufacturers can be selected.
Although these different inductors have similar technical specifications, they can show a significant deviation when handling EMI frequency interferences. The filter circuit has to match the DC-DC converter characteristics over the full frequency range, so Recom now offers the RLS series of inductors which have been pre-tested and matched with its DC-DC converters to pass both conducted and radiated interference limits.
Many other manufacturers only test for conducted noise because it can be measured without needing an expensive EMC chamber, but when test house approval is required, designs can fail EMC due to radiated noise. With the combined Recom filter and modules, designers can be confident that they can pass both conducted and radiated EMC tests.
Samples and OEM pricing are available from all authorized distributors or directly from Recom.
