Marmite!! Posted May 15, 2007 Share Posted May 15, 2007 I need to find a replacement capacitor very urgently, problem is I've done a search on the info on the capacitor case & nothing comes up.. this is what I have.. TW 250 380 W03 BXS UK MADE 8633 Anyone decipher that lot :dunno: Cheers Lee Quote Link to comment Share on other sites More sharing options...
andrewroberts.1953 Posted May 16, 2007 Share Posted May 16, 2007 What is this cap out of? Does it have any other makings? Andy Quote Link to comment Share on other sites More sharing options...
Marmite!! Posted May 16, 2007 Author Share Posted May 16, 2007 no other markings, it's out of a Shrike MkV which we use for our pyro http://www.bdlsystems.com/downloads/ShrikeExploder.pdf there's two of them in there but one of them has broke loose & the poss lead has broken off.. was thinking if I could get an approx value I would replace them as a pair.. the dimensions are 18mm x 35mm approx the input voltage is 15volts with an output of 319v-400v Quote Link to comment Share on other sites More sharing options...
Mark Posted May 16, 2007 Share Posted May 16, 2007 You could try Maplins as an alternative?? Quote Link to comment Share on other sites More sharing options...

Richard Farrant Posted May 16, 2007 Share Posted May 16, 2007 Try RS Components rswww.com Quote Link to comment Share on other sites More sharing options...
Marmite!! Posted May 16, 2007 Author Share Posted May 16, 2007 Try RS Components rswww.com Tried them to but they can't help unless I can give them some values :dunno: Quote Link to comment Share on other sites More sharing options...
Mark Posted May 16, 2007 Share Posted May 16, 2007 Can't Shrike help then with a replacement as they sold it? Quote Link to comment Share on other sites More sharing options...
fv1609 Posted May 16, 2007 Share Posted May 16, 2007 I need to find a replacement capacitor very urgently, problem is I've done a search on the info on the capacitor case & nothing comes up.. this is what I have.. TW 250 380 W03 BXS UK MADE 8633 Anyone decipher that lot :dunno: Cheers Lee Lee I don't understand about the rating. Are you sure the component is actually a capacitor? Input 15v output 319v etc is not the way a capacitor would be rated. It would normally have a capacity value microfarads, picofarads etc & a max voltage working often quoted as a DC & an AC value. TW I assume is the manufacturer & 230 380 the part no. Searching for TW250380 yields nothing. Just 250380 reveals items from surgical bone nibblers to a lens but no capacitors. WO3 BXS reveals nothing, but could it be a post code. 8633 reveals items from a US roller bearing to a German toilet, but no capacitors. I can't look through capacitors & see if something matches as more than a quarter of a million are listed. So is this a capacitor? Perhaps it is a step up transformer. Disconnect the good one & measure resistance values & compare with the suspect one. If they are all open circuit maybe it is a capacitor. I can always measure the capacity for you on a capacitance bridge. Quote Link to comment Share on other sites More sharing options...
Marmite!! Posted May 16, 2007 Author Share Posted May 16, 2007 Hi Clive, sorry when I say input voltage I mean voltage of the battery, there is a step up transformer in the circuit, I'm 99.9999999% sure they are capacitors as there's nothing else big enough on the board to hold an initiating charge of 400v... also the maker is http://www.bhc.co.uk/ who only make capacitors, emailed them several time & no reply, nothing in there catalogue that matches, this shrike was made in 1986, going back to Maplins tonight to have a search for two fat capacitors to stick in there.. Mark, BDL Systems that make the shrike will not give any info as they were supplied under a MOD contract.. :-( Quote Link to comment Share on other sites More sharing options...
R Cubed Posted May 24, 2007 Share Posted May 24, 2007 What about trying a explosive demolition company for any spares they might use or might be able to give some advice where to go.... :shake: R Cubed Quote Link to comment Share on other sites More sharing options...
R Cubed Posted May 24, 2007 Share Posted May 24, 2007 Sorry posted tooo quickly, what about some pics of this thing might jogg some memories. Quote Link to comment Share on other sites More sharing options...
