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.
FEATURES
ꢀꢀThe BNX002 incorporates feed-thru-type barrier layer
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.
ꢀꢀThe filter is extremely compact since only one filter block
is needed to completely eliminate noise from both the
positive and ground lines.
ꢀꢀThere are no connections in the feed-thru current circuits,
thus ensuring highly reliable performance.
ꢀꢀBoth the input/output terminals and the grounding terminal
are aligned in the same direction, permitting fast and easy
installation on any type of PC board.
ꢀꢀNon polarized—but care must be taken to ensure that
terminal with inductor on ground line faces EMI source.
