I have an old TV with some caps rated 6,000 volts and if I need to replace them could I put 3 .003 mfd @ 1600v in series to replace a .001 @ 6,000v?

You would want to use 3 capacitors of at least 2000V rating. If you put 4 of these in series you would get 0.00075uF at 6400V. You can buy 6000V rated 0.001uF caps through Allied Electronics (part number 225-6015) and other vendors. These are made by ASC. andrefranc 11-20-2009, 07:16 PM I tried Allied for this cap and they told me minimum order was 97 of them and leed time was 13 weeks. I know I figured wrong on the voltage. Would need 4 at .004 mfd I think. Eric H 11-20-2009, 08:27 PM Justradios at http://www.justradios.com/ has these for a few bucks each, I think the 8000 volt ones are actually a little cheaper and are still smaller than the originals. I wonder when Allied went to the minimum order deal, I've bought from them before and there was no such thing then, but that's been a few years. Phil Nelson 11-20-2009, 09:50 PM That doesn't sound right. I bought small numbers of caps from Allied twice in the last month or two. Don't remember the totals offhand, but it was maybe $20 for one order, $30 something for the other . . . nothing outrageous, or I would have tried somewhere else. Phil Nelson sean 11-21-2009, 09:13 AM Allied's website says there are 30 in stock at $4.12 each. Allied 225-6015 (http://www.alliedelec.com/search/searchresults.aspx?N=0&Ntk=Primary&Ntt=225-6015) bandersen 11-22-2009, 01:13 AM It's the 8KV ones that have a minimum quantity of 91. They're only $1.68. http://www.alliedelec.com/search/productdetail.aspx?SKU=2256020 andrefranc 11-25-2009, 06:24 AM Thanks to all and I ordered some caps. from JustRadios. |
