14,000 uf now that's a BAC!!! Your thinking is correct. Connecting capacitors together works just opposite to connecting resistors together. * Capacitors in parallel add like resistors in series [Ct = C1 + C2 + ... Cn]. * Capacitors in series add l

I ordered a capacitor book. I reinstalled the crystal that i purchased from digikey, and swapped the two load capacitors out from 30pf to 10PF which works out well with the datasheet that calls for 10pf Load Capacitance, and this equation (CL = (C1

Good afternoon, 22C +/-2C, 40%RH +/- 5% is a good starting point. I wonder if any standard requires floor temperature and humidity control. Most of requiremens come from solder paste manufacturers. BR, Pavel.

Hi Darren, First thing is to check the footprint against the manufacturers: http://search.murata.co.jp/Ceramy/image/img/A18X/C2EB3M.pdf as this may behave differently thermally to other 0805 devices due to the exceptional number of layers inside.

When you get a BOM like this: PartNo;ID's;Qty;Package 1234;c1,c2,c3,c76,c99;5;0805 Does anyone use any simple tools out there that would automatically expand the BOM to one ident/line so that things are easier to find & compare with the pick and p
