Industrial Control: Inverters, servo drives, and other equipment generate strong electromagnetic noise during operation. Without EMI filters, this noise can interfere with nearby sensors, PLCs, and other devices, leading to malfunctions or data errors.
Communication Equipment: Mobile phone base stations, routers, and other equipment must meet electromagnetic compatibility standards such as EN 301 489. EMI filters prevent stray signals emitted by these devices from affecting communication on other frequency bands and avoid signal interruptions caused by external environmental noise.
New Energy and Rail Transit: Photovoltaic inverters, electric vehicle charging stations, and other equipment must pass IEC 61000 series standard tests. Filters suppress DC-side ripple pollution of the power grid and prevent harmonic resonance.
Medical Equipment: Precision instruments such as MRI scanners and CT scanners are extremely sensitive to electromagnetic noise. EMI filters ensure stable operation of these devices in complex electromagnetic environments, preventing diagnostic data deviations.
