Hi Dmitry,
I guess I agree with Terry. The problem seems to be with the outer
tape only that really serves no function other than a label. The
real question, I thinking, is what caused the tape to come loose
since I too have never seen a CDE cap that way. My CDE caps look as
good as your Russian caps do. If the shipment really did get
subjected to -40 C, this might be a concern since many comercial
components have a -55 to 150 C storage temp rating. The CDE data
sheet seems to indicate a -55 to 105 C operating temp range so you
are probably OK. You might take one of the worst looking caps and
peel off the outer tape and see if this is the only thing that looks
questionable. If you got them directly from CDE, you might email
them with a picture and get their opinion. Are they all that way or
just a small fraction of them???
Good luck,
Gerry R"
I have a large stock of CDE mylar bypass capacitors purchased in
the 1960's and used for wave filters. (The Q is plenty good enough
at frequencies of a few kHz.) They have paper stickers indicating
the value and a lot of those have come loose over the years. I
usually mark the value on them with a fine-point "Sharpie" pen "just
in case".
They're sorted by value and when I need to make a filter I select the
parallel combination which gives me the odd values I usually need.
