APITech Filter arrays and plates provide an electromagnetic interference (EMI) filtered signal line between electronic system modules. This reduces cost, providing an economical method to meet electromagnetic compatibility (EMC) requirements. Benefits include reducing labor, eliminating the need to assemble filters into a bulkhead; outperforming surface mount EMI filters at frequencies above 50 MHz and reducing the risk of damage to filter elements due to thermal shock and installation. Their size maximizes real estate on a printed circuit board (PCB) and is capable of mixed schematics in a single filter plate package. APITech filters also improve reliability; every filter plate is 100% tested for defined key parameters
