Thanks Fred. Unfortunately, "catalog set" is the operative
phrase; it's the same collection of one to 3-page locked-
file pieces available from the EPCOS website. Yes, nicely
organized by Eastern Components, but still broken down into
tiny useless bits. Compare that to Ferroxcube's convenient
BTW, I just checked on EPCOS' CDROM, and it's organized
the same way: select a part number and get a one-page .pdf
file. However, at least once the datasheet page appears,
Acrobat shows a clickable index gets you to single-page
datsheets for other parts. That's a modest improvement.
Also, the .pdf files on the CDROM aren't locked, so you
can manually make up a collection of ELP cores, etc.
That's a badly-needed fix. This security business that
some manufacturer's are doing lately, locking their data
sheets and catalogs, is a royal pain in the Bu@*(&)&$.
