Industrial System EMI Filters

At APITech, we do it all from package design and metalworking for our industrial EMI filters, including EMC testing. Our engineers will design and build a custom EMI filter to satisfy global EMC regulations, improve speed-to-market, overcome space constraints, and withstand harsh environmental conditions. The plug-and-play EMI filter designs cover a range of industrial, automation, and instrumentation applications that address any EMI filtering needs with current ratings as high as 500 Amps.
