Riverside, Calif., July 15, 2009 Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the new SRF series of line filters for electromagnetic interference (EMI) suppression. Designated Bourns® models SRF0504, SRF0602, SRF0905, SRF1006 and SRF1306, the new lead free line filters feature inductance values from 0.55 µH up to 6500 µH and current ratings as high as 5 amps. Line filters are required in personal computers, data terminals, test equipment and process controllers for high frequency suppression into or out of electronic equipment. The new devices are RoHS* compliant and offer excellent EMI suppression capability at high frequencies for a broad range of applications that require minimization of interference.
&;quot;It is important to match the right line filter to a particular application, that is why Bourns is pleased to expand its product line with a new series of line filters for appropriate EMI suppression,” said Guido Zehnder, Inductive Product Line Manager for Bourns, Inc. This new series of line filters give our customers a wide range of inductance values and are well suited for applications that require minimal interference such as computer, communication, instrumentation, industrial and medical applications.&;quot;
