Hi guys,

I've been parts shopping for a little project that I'm looking to build, and I got stumped by this. The build requires a very exact matched pair of capacitors giving as close a total capacitance as possible to 1020pf (within 0.5% tolerance).

I noticed that RS has some silver micas that are rated to 1% tolerance for 1000pf which I can then combine it with another small silver mica rated to 0.5% tolerance, and get my 1020pf.

Alternatively, I can grab a LC meter and head down to the nearby electronics shop and cherry pick out some silver micas...

Hi all,

I have just ordered for myself a kit for AADE's LC meter, and was reading through the instruction manual to get a hang of what's involved to get it together.

One thing I noticed as I was going through the parts list is that the design consisted of a pair of 2 capacitors, C2a and C2b, of which the total capacitance is vital to the operation of this thing.

I was actually considering swopping the capacitors out for some higher quality ones Wimas, but I guess I won't be able to do it now.

I don't like a tool that I don't understand...

Re: Need some help on Blue ESR meter assembly



Which hole for C6 is for the positive leg? The "+" sign is printed right in the middle between two holes which isn't quite helpful ...

Hi all,

Sorry in advance for my extremely noob-cake questions

I got myself a Blue ESR meter lately, and got a bit stumped with the final bit of its assembly.

To make it easier for you guys to see what I mean, here is how it looks like now:


I managed to figure out where the two variable pots go as well as the 2 blue LED lights, however what got me are 3 little capacitors. The ones that are 22uF, 33nF and 0.47uF.

There are two 22uF capacitors on the schematic, and the bigger one I have soldered on, but the smaller...
