" Block type <strong>EMI</strong>FILr are resin encased, built-in, high<br />
performance <strong>EMI</strong> suppression filters, which use a feedthru<br />
capacitor having excellent high frequency<br />
characteristics.<br />
" Used when the noise frequency is high, or when extreme<br />
countermeasures are required.<br />
" The high performance <strong>EMI</strong>FILr BNX series exhibits<br />
significant noise suppression effects over a wide<br />
frequency band (extending from 100kHz to 1GHz) in <strong>DC</strong><br />
power lines.<br />
