EMI LEADED FILTERS

EMI SUPPRESSION FILTERS

BLOCK FILTERS

BNX002/003/005 Series

Block-type BNX002 filters completely eliminate noise from

extremely wide frequency bands. The BNX002 is perfect

for use in DC power circuits and is designed to perform

superbly — through the use of through-type barrier layer

capacitors, monolithic chip capacitors and bead inductors.

Each block contains a number of compact EMI suppression

filters. In addition, the input/output terminals and the grounding

terminal are aligned in the same direction, thus permitting fast

and easy assembly on any type of PC board.

APPLICATIONS

Noise elimination from signal lines and DC power sources in a

variety of switching power sources, engine control units, digital

equipment and computer terminals.

is needed to completely eliminate noise from both the

positive and ground lines.

thus ensuring highly reliable performance.

are aligned in the same direction, permitting fast and easy

installation on any type of PC board.

FEATURES

capacitor and a chip capacitor which are interconnected.

This combination enables the BNX002 to achieve a

significantly large insertion loss throughout the extremely

wide frequency range of 0.5MHz to 1GHz, which covers

the AM and UHF-TV broadcast frequency bands.
