nanokid Posted August 25, 2006 Report Share Posted August 25, 2006 Looking to build this http://electronics-diy.com/schematics/BH1417_fm_transmitter.htmI have found all the parts but two. I can't find a 1uf 16V electrolytic cap. Can anyone suggest where to find one or an alternative?I also can't find a Soshin GFWB3. THis is not as critical because It is not mandatory.

audioguru Posted August 25, 2006 Report Share Posted August 25, 2006 The 1uF/16V capacitors are only used at a few volts so only their value is important. Capacitors with a higher voltage rating will work the same but might be bigger. 1uF/25V or 1uF/35V might be small enough to fit on ther pcb.You are using the pcb, aren't you? This circuit works at around 100MHz and won't work on a breadboard. Quote Link to comment Share on other sites More sharing options...
Guest nanop Posted August 25, 2006 Report Share Posted August 25, 2006 Are u kidding about the 1uf 16V electrolytic cap ! :)Those can be bought just about anywhere. They can be bought online, and even at Radioshack, "that usually sucks"Here's the site for Radioshack : http://www.radioshack.com/product/index.jsp?productId=2062378&cp=2032058.2032230.2032267&pg=2&allCount=101&fbn=Type%2FElectrolytic+Capacitors&f=PAD%2FProduct+Type%2FElectrolytic+Capacitors&fbc=1&parentPage=familyLong URL...BTW, Where r u from?and what does the W mean after 1 Quote Link to comment Share on other sites More sharing options...

nanokid Posted August 26, 2006 Author Report Share Posted August 26, 2006 yes Im using the pcb. Im using batchpcb.com. Ive used them before, much better pricing than advanced circuits. and Ive looked on mouser and digikey for a 1uf 16v radial electrolytic capacitor and i haven't found them. I even looked under tantalum but the only ones they have are non stocked and have outrageous mins. Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted August 26, 2006 Report Share Posted August 26, 2006 Type this in "1uf 16v" At Mouser and you get about 450 optionsAt Digikey you get about 165 options Quote Link to comment Share on other sites More sharing options...
nanokid Posted August 26, 2006 Author Report Share Posted August 26, 2006 I've done that several times. I need a radial electrolytic cap. There are none available. I guess if i cant find one I could always use a ceramic, but I def don't want to use a smd cap. Quote Link to comment Share on other sites More sharing options...
audioguru Posted August 26, 2006 Report Share Posted August 26, 2006 Digikey has many brands of 1uF/50V radial electrolytic capacitors that will probably fit on your pcb. They don't have them in 16V, 25V nor 35V anymore. 50V capacitors will work fine in your circuit. Quote Link to comment Share on other sites More sharing options...
