Eliminating EMI/RFI interference has become a stringently enforced matter and needs to be considered at the early stages of design for all electronic systems. Both internal and external interference sources have a major impact on the successful EMC performance of a new system.
Shielding alone is unsatisfactory in shunting unwanted harmonics, conducted or radiated, on power/ control lines that run through compartments of an electronic enclosure. This is particularly applicable in systems operating at frequencies above 50 MHz. Isolation and the incorporation of feed-thru filters (Filter Plates) to facilitate entering or leaving sensitive compartments in an assembly are excellent methods to bring electronic interdependent functions/systems into compliance.
Filter Plates allow a means of interfacing voltage and/or data (controlling instructions) to distant areas of a system without compromising its performance. Filter Plates provide excellent isolation from 5 MHz to 18 GHz and beyond, reduce the labor involved for installation, as well as reduce the risk of damaging filter elements during installation. Connecting to these Filter Plates is easily accomplished through several methods, either ribbon style connectors, harnesses, hard wiring or directly soldering leads at a 90° angle to the printed circuit board.
