Can anyone give me a part # and  mfgr.  for a 22000MFD 25v   105c filter cap?    or what ever is better.   ( Must have screw  terminals.)            Thanks      Bill S.

Screw terminals are generally a pain.  But... 338-1252-ND from digikey

gets everything you want except the temperature spec - 95C instead of

105C.  If you aren't installing it in a certified harsh environment 95C

might be fine.

    I agree. This part number will be fine. However, avoid

    any ideas about substituting a wired device of the same

    ratings over the screw-terminal devices. Their internal

    construction is not as well suited for high-ripple current

    filtering that we're looking for in this application.

    It's that "computer grade" thing that makes the difference

    and all these puppies come with 10-32 screw terminals.

Matt   Thanks for the quick reply.     What do you mean by,  generally a 

pain?  What problems can I expect to incounter with screw terminals?    Bill

Bill, Matt and all,



FWIW, I installed such a screw terminal capacitor in our airplane three 

years ago, and we have been flying for two years now, without any problem.

Ahhh..  I just gripe because screw terminals seem unnecessairly fiddly.  

Electrical components are often mounted in places where access/vision is

limited.  Threading small screws through lugs crimped to springy wire can

be  a test of dexterity and patience.  No big deal, but I like to have

things built for quick serviceability.



As a possible alternative, I remember seeing threaded lug to spade

adapters on the tops of the older Bosch (at least) automotive ignition

coils.  A threaded stud sticks out of the top of the coil.  Captured by a

nut threaded onto the stud is a piece of tinned metal.  The end of that

piece of metal is properly sized/formed to accept female spade terminals. 

I did a quick online search and couldn't find what I was looking for... 

Maybe somebody knows what these things are actually called..

It should be pretty easy to make such a thing.

Steinair has faston adapters for use on terminal strips that could be cut in half and used.  Don

   Why drive up parts count? What advantage is gained by placing an

   adapter on a threaded stud to accommodate a fast-on terminal when

   a simple ring terminal to the same stud will suffice? If you have

   concerns about maintaining joint integrity in the threaded fastener,

   those concerns don't go away just because you've turned a fast-on

   terminal into a ring-terminal with an adapter.

Bob,

This was in response to Matt's comment about not wanting to use screw terminals becausr of the difficulty in doing maintenance later on in blind spots or difficult to reach spots.  He said that he preferred fast on type hook ups.  This was a way that faston type could be used with existing screw type caps.

Hey Bob,



I think I started this twist...  I just don't like ring terminals when

trying to make a connection in the blind.  I wasn't concerned about joint

integrity.  I agree with your point about parts count..
