well, I am very glad that you are having the fun this time.

I matched 1000 MOSFET once for a GB.
The first 100 was still fun......

But then you have the motivation for doing something good for the victims in Japan.
So my most sincere respect for that action.

No. I wrote an article about how to match them and why.

I should add that LT1083 is a better choice for making a 2A CCS than the LM317 mentioned in the article.

The people from Fukushima are the ones who are really suffering.
But I have no sympathy for Tepco, and not much for the Japanese government either.

Hi

I've ordered 20pcs of 220R resistors and the matched pairs are in 8, which means I get 16 pcs of matched resistors, correct? And the balance of 4 is not matched, correct?

Hey pmchoong,

I'll update your order to two sets of 8 matched resistors (16 in total). As of right now, we are only offering the resistors in matched sets.
