Resistor selection parameters
WebDec 13, 2016 · The amount of attenuation of both the differential mode signal and the common-mode noise signal depends on the frequency. These characteristics of the common mode choke coil are represented as differential mode insertion loss Sdd21 and common mode insertion loss Scc21. (Sdd21 and Scc21 are among the mixed-mode 4-port … WebJul 15, 2016 · DC resistance is an important parameter in DC-DC converters design as the resistance leads to I 2 R losses thus reducing the efficiency. Tolerance is the variation in the inductance value of an actual inductor compared to the specified value in the data sheet. This could result in unwanted shift in frequency selection of an RF filter.
