2. Using The Block Type EMIFILr Effectively
(1) How to use 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 problems. Therefore, grounding conditions may affect
the performance of the filter and attention should be paid to
the following for effective use.
(2) Self-heating
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) Design maximized grounding area in the P.C. board,
(a) Use P.C. board with our recommendation on hole
(b) Solder the terminals to the P.C. board with
Continued from the preceding page.
(b) Minimize the distance between ground of the P.C.
(c) Insert the terminals into the holes on P.C. board
(d) Don't connect PSG terminal with CG terminal directly.
(c) After installing this product in your product, please
