High-frequency signals (EMI) on ground is never good news - they interfere with normal operation of equipment and cause electrical overstress (EOS). However it is easy to block propagation of electromagnetic interference on ground by installing highly-effective ground EMI filters in ground lines. Our unique patented ground EMI filters provide very low impedance for DC and mains' power while effectively blocking propagation of high-frequency currents throughout facility or equipment ground. Ground filters meet safety standards, as well as SEMI E176, ANSI/ESD S6.1 and ANSI/ESD S20.20.
OnFILTER offers ground EMI filters for the facility and for grounding inside the equipment, providing universal protection against propagation of EMI. Select below the category of ground EMI filters of your interest for more details.
Installs in-line with facility grounding to blocks propagation of EMI from noisy equipment throughout the factory
Installs in-line with ESD grounding inside equipment to block EMI propagation throughout the tool
Installs on DIN rail in-line with grounding entering the panel to block EMI propagation from the "outside"
