A slimmer and more sophisticated surface-mount EMI suppression filter is now available from Murata Electronics North America. The BNX022 measures just 1 by 9 by 3 mm and weighs 0.8 g. Murata claims that it's significantly smaller and thinner than previous versions and other manufacturers' filters. The trimmer dimensions are a result of advancements in capacitor materials and terminal formation technology, as well as improved packaging. In addition, the enhanced EMI filter achieves a high level of noise suppression which in dc power supply lines, helps improve the performance in various entertainment, industrial, and technology equipment including flat panel displays, DVD players, and servers.
The surface-mount EMI filter series offers a large insertion loss frequency band range (1 MHz to 1 GHz), a rated voltage of 50 V, and a current of 10 A. It's available now for $3.50. Additional information can be found at www.murata.com.
