Looking for more info about, possible experience with, or measurements of the 2sk3557 from Sanyo. The data sheet claims ultra-low noise, low capacitance, and high gm. Wonder how it compares to bf862 for instance.
SANYO: 2SK3557
SANYO: 2SK3557
Specs including Ciss and noise are similar to BF862.
But good to know one can buy direct, even though USD3- for a SOT23 JFET !!

digikey has them for 0.85CDN dollars which is a lot more than what the bf862 costs. Not worth it, indeed.
I have been looking for it 2 years ago, including trying to source from Japan, to no vail.
All of a sudden, you manage to name 2 sources.
Sanyo direct was non-existent then, and DK did not have it.
Now even Farnell has it, and is cheaper than DK for a change (at least in the EU) and almost same price as BF862.
But then both of them are Rank 7, which is just the same as BF862. And I was looking for Rank 6 (more friendly Idss).
Another one I was trying to find was 2SK771 Rank 4, equally unobtainium.
Also 2SK3666 Rank 4. Rank 3 is available at DK.

Yes but that's Rank 5. I was looking for Rank 4 (lower Idss).
DK has what SanyoDirect offers, nothing else.

I have never purchased anything through this means before. You would hope that they were a credible business.
