There is no essential difference in the core structure between filter capacitors and ordinary capacitors (both are composed of plates and dielectrics), but the differences in design goals, performance focus, and application scenarios make them significantly different in practical use. The main differences between the two are as follows:
As the core component of power electronic systems, filtering capacitors play a crucial role in eliminating harmonics, stabilizing voltage, and improving energy efficiency. The global and Chinese markets have formed a diversified brand landscape, with different manufacturers deeply cultivating segmented fields based on technological accumulation and application scenarios. The following is a classification and analysis of the main brands:
Filter capacitors are extremely common and critical passive components in electronic circuits, whose core function is to "smooth" voltage and "filter out" unwanted AC noise or interference. The following are its main application scenarios:
