Thanks, Don. Looked back at my neatly bagged inventory and found the bag I marked "271". That's what I get for trying to be organized.
Here's what I'll use: C72: "271" C45: "010" (although it doesn't have a black cap to indicate "temperature stable") C33: "229" C198: "270" --ae0mm ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On July 20, 2018 12:44 PM, Don Wilhelm <[email protected]> wrote: > > > Those capacitors are using the standard 3 digit code - two significant > > digits followed by a multiplier (9 is used for a multiplier of 0.1 in > > this type of identification). > > 010 is 1pF > > 030 is 3pF > > 270 is 27pF > > 229 is 2.2pF > > I don't know where your 270pF (marked 271) capacitor may be, you didn't > > list it. > > With manufacturers discontinuing many thru-hole components, it is > > getting more and more difficult to keep the manuals current with the > > available supply. > > 73, > > Don W3FPR > > On 7/20/2018 12:10 PM, AE0MM via Elecraft wrote: > > > I'm having trouble identifying a few capacitors used in the assembly of the > > K2 RF board. > > > > C72: "271" > > > > C45: NPO "1", black top > > > > C33: 2.2pf "2R2" or "2" > > > > C198: NPO "27" or "272" > > > > What I have: > > > > a blue "010" > > > > a blue "030" > > > > a yellow "270" > > > > a yellow "229" > > > > I suspect the "229" is a 2.2pf capacitor for C33. > > > > The "270" could be 27 or 270pf, but I'm not sure; it might be for C72. > > > > The "010" could be the 1pf for C45, but it doesn't have a black top. > > > > Could the "030" be for C198?
