!NOTICE
"Matching condition should be evaluated to perform stable
electrical characteristics which are specified.
"In case of covering filter with over coat, conditions, such
as material of resin, cure temperature and so on should
be evaluated well.
"Washing of filter is not acceptable due to unsealed
construction.
"Filter might be damaged when an excess stress was
applied.
