The 50 Ohm insertion loss data which appears in our catalog represents an industry standard to allow comparison of different manufacturers’ products against a known standard. This is generally the impedance used to test conformance of a system to various military and other EMI standards. In practice, filters are source and load impedance sensitive. The actual load impedance varies greatly from system to system. It is therefore often easier to test the filter and system to determine the actual combined performance.
