The invention discloses a filter capacitor parameter determination method applied to EMC performance, and relates to the technical field of electromagnetic compatibility testing, and the method comprises the steps: collecting a plurality of cases with an electromagnetic incompatibility problem in a testing process, and carrying out the verification and analysis; carrying out research and analysis on the type selection of the filter capacitor and the reason of electric leakage; optimizing the type selection parameters of the filter device; and a conclusion formed by research is verified under different detection devices. In the electromagnetic compatibility problem rectification and debugging process, the filter circuit can be rapidly built, the appropriate filter capacitor can be selected, the EMI problem of equipment can be more conveniently and rapidly solved through the generated limit filter capacitor limit value table, and the electric leakage risk caused by improper device type selection in the electrom
