FSBUS Capacitors

Featured Replies

Hello Everyone,I was hoping if someone could help me with some FSBUS capacitors questions. I'm fairly cluey when it come to electronics but I'm not too sure about this one.I've seen a few component lists for constructing your FSBUS and they recommend certain types of capacitors.In Australia, I guess the best company for buying components is Farnell. The voltage rating mention in the components lists (eg. 35V) at 1uF do not exsist but in 50V they do. Is this an issue?Is there a problem using ceramic radial capacitors instead of Electrolytic Radials?In the Farnell Catalogue they also mention non-polarised capacitors, would there be any issue using those?I've made a price listing with all of the components from Farnell but I've been stuck on the capacitor issue. I'll definately make the price list available on here over the next month or so when I know the system works, I have selected the right components and that it works flawlessly.Any help would be appreciated and I look forward to your replys!Regards,BRAD HELLER

Depending how they are used in the circuit, they or may not cause problems. It really depends on the circuit they're being used in.For example, if the caps are used in filtering AC signals, they should be non-polarized (typically ceramic). Examples include the decoupling caps used with ICs. You'll see these placed close to the Vcc or Gnd pins of chips on a board.Hopes this helps.-Leo

Thanks Leo,Your a life saver mate!Now I can finish of my price list and get the parts ordered.Kind Regards,BRAD HELLER.

Brad, Farnells are pretty expensive, I have sourced just about all the components for FSBus here in Australia from Jaycar & DickSmith, Give those guys a try first, then Farnell or RS-Components.I do have a home brew (even etched the boards here) working FSBus system, However I still have to etch the FSKey Board.Sydney OZ.Cheers Glenn.

Thanks for that Glenn!When it comes time I might pick your brains if I have any troubles if thats ok with you?I'm away on business at the moment but when I get back I'm going to try to source a department at work to see if I can use their facilities to make the PCB's.Kind Regards,BRAD [email protected]

No Probs mate, You don't happen to be with the RAAF in 75SQN at all do you ? Just noticed you Nickname & email.Anyways more than Glad to help you out it's a pretty neat system to build & works well, not sure where you are normally located but I am around Horsley Park way West of Sydney.Cheers Glenn.
