This product effectively prevents undesired radiation and
external noise from going out / entering the circuit by
grounding the high frequency components which cause
noise problems. Therefore, grounding conditions may affect
the performance of the filter and attention should be paid to
the following for effective use.
(a) Design maximized grounding area in the P.C. board,
and grounding pattern for all the grounding terminals
of the product to be connected. (Please follow the
specified recommendations.)
(b) Minimize the distance between ground of the P.C.
board and the ground plate of the product.
(Recommend unsing the through hole connection
between grounding area both of component side and
bottom side.)
(c) Insert the terminals into the holes on P.C. board
completely.
(d) Don't connect PSG terminal with CG terminal directly.
(See the item 1. Terminal Layout)
(1) How to use effectively
Use a bilateral P.C. board. Insert the BNX into the P.C.board until
the root of the terminal is secured, then solder.

Though this product has a large rated current, localized
selfheating may be caused depending on soldering
conditions. To avoid this, attention should be paid to the
following:
(a) Use P.C. board with our recommendation on hole
diameter / land pattern dimensions, mentioned in the
right hand drawing, especially for 4 terminals which
pass current.
(b) Solder the terminals to the P.C. board with
soldercover area at least 90%. Otherwise, excess self-
heating at connection between terminals and P.C.
board may lead to smoke and / or fire of the product
even when operating at rated current.
(c) After installing this product in your product, please
make sure the self-heating is within the rated current
recommended.
