It is often necessary to add additional filter components to a DC/DC converter module to meet Class A or Class B EMC limits. 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. As it is also essential that the filter circuit matches the DC/DC converter characteristics over the full frequency range, RECOM now offers its RLS series of inductors which have been pre-tested and matched with RECOM 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 RECOM’s solution, the customer 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.
