Параметры готового электронного изделия могут не соответствовать расчетным, что обусловлено, например, неучтенными паразитными связями. По этой причине при конструировании помехоподавляющих фильтров эффективность фильтрации может быть занижена по сравнению с ожидаемой. Проведено моделирование изменения амплитудно-частотной характеристики фильтра, обусловленное влиянием паразитных параметров компонентов и элементов механического крепежа, в диапазоне частот от 10 кГц до 1 ГГц. Предложены рекомендации по модификации элементов механического крепления и оптимизации параметров дросселей низкой частоты.

For a noise-reduction filter, the parameters of the manufactured device often do not fit the expected parameters during development, what is caused by the spread of the parameters of the electronic components or their parasitic parameters, as well as due to the presence of its own capacitance and inductance of the frequency response assembly. In this article, the influence of parasitic parameters of components and fasteners on the filter frequency response is considered. Utilizing the electronic simulator software, the filter parameters were modeled in the frequency range from 10 kHz to 1 GHz. Based on the simulation results, recommendations were given for optimizing the filter mounting elements and changing the inductance of low-frequency chokes.
