RoHS Compliance This component is compliant with RoHS directive. This component was always RoHS compliant from the first date of manufacture. SF2445E RF Filter for Mobile Communication Applications Low Insertion Loss 846 MHz 3.0 x 3.0 x 1.3 mm Surface-Mount Case The SAW filters are 100% tested in a test fixture, and Murata has made the best effort to correlate such test results to the performance on the cus- SAW Filter tomers board with recommended matching.
