11. Notice
11.1. Using the block type EMIFIL® (BNX) effectively
This product effectively prevents undesired radiation
and external noise from going out / entering the circuit
by grounding the high frequency components which
cause noise problem. Therefore, grouding condition may
affect on the performance of the filter and following
attentions should be paid for effective use.
(1) Design maximized grounding area in the P.C. board,
and grounding pattern for all the grounding terminals of
the product to be connected.(Recommended to use our
recommendation in this spec.)
(2) Minimize the distance between ground of the P.C.
board and the ground plate of the product.
(Recommended to use through-hole connection
between grounding area both of component side and
bottom side.
(3) Insert the terminals into the holes on P.C. board
completely.
(4) Don’t connect PSG terminal with CG terminal
directly. (See the item 4. TERMINAL LAYOUT)
11.2. Self-heating
Though this product has a large rated current, the localized
self-heating may be caused depending on soldering
conditions. To avoid this,following attention should be paid.
(1) 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.
(2)Solder the terminals to the P.C.board with solder-cover
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.
(3)After installing this product in your product, please make
sure of the self-heating with the rated current.
