Types of PCB EMI Filters
DOREXS offers multiple types of PCB EMI filters to meet different electrical requirements and PCB layout constraints.
Single-Stage PCB EMI Filters
Single-stage PCB EMI filters provide basic high-frequency noise attenuation and are suitable for applications with less stringent electromagnetic compatibility requirements. Their compact package makes them ideal for space-constrained PCB designs. Rated current ranges from 1A to 20A. They are suitable for consumer electronics, office equipment, and low-power industrial circuit boards.
Multi-Stage PCB EMI Filters
Multistage PCB EMI filters provide stronger attenuation performance over a wider frequency range. They effectively suppress both common-mode and differential-mode interference, achieving effective filtering within the typical conducted EMI frequency range. They offer stable insertion loss and low leakage current. Multistage PCB EMI filters are widely used in applications with stringent electromagnetic compatibility (EMC) requirements, such as industrial automation controllers, medical electronic equipment, communication systems, and precision instruments.
