EMI LEADED FILTERS

EMI SUPPRESSION FILTERS

BLOCK FILTERS

BNP002/004 Series

Block-type BNP002 filters completely eliminate noise from

extremely wide frequency bands. The BNP002 is ideal for

eliminating noise in logic signal circuits and is designed to

perform superbly through the use of through-type barrier layer

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

engine control units, digital equipment and computer terminals.

one filter block, minimum board space is utilized.

thus ensuring highly reliable performance.

are aligned in the same direction, permitting fast and easy

installation on any type of PC board.

FEATURES

layer capacitors in Pi circuits, obtaining significantly large

insertion losses over an extremely wide frequency

range — from 15MHz up to 1GHz.

which is ideal for eliminating noise from any circuit in which

the signal frequency and the noise frequency are relatively

close together.
