Hi,

I've one schematic that I'm trying to make for a new board, some of the parts have one letter next to the value, but I've no clue what is the letter, perhaps precision components?

The parts are:

C - 0.01pF B
C - 0.1 pF F
C - 0.001pF B
C - 4pF CH
C - 27pF SL

And also there are two obsoletes 2SC945AQ what would be a good sub for this one?

I'll try to post the schematic later.

Nuno_pt:
Looking at google could the letters be the tolerance of the capacitors?

B - +- 0.1pF
F - +- 1%

But can't find the CH or SL :-//

I'll try to make the schematic with Kicad and post it here.

Schematic add.

TimFox:
Are the first three components (capacitors) values typos for microfarads?  0.001 pF is not feasible.

Nuno_pt:
Yes, they are typos, should be uF, all the capacitors

According to this document: http://www.rockby.com.au/DSheets/10059.pdf
CH: 0±60 (ppm/°C), -25 to +85 °C temperature range
SL: +350 to -1000 (ppm/°C), +20 to +85 °C temperature range
