Which grade (GR, BL, V, ..) ?

There is a series of old 3-pin N-cannel low noise & switching J-FET's called J108, J109 & J110. I think Siliconix began with them in the end of the 70's.
These types were later made by almost all manufacturers and are in large stocks. Just make a search on "siliconix j109" to see.

These are most confusing as the japanese don't print 2S before J109 on the actual 2SJ109 device.

So the 3-leg J109 is now misstaken for 2SJ109, even by many honest suppliers (if there are any).

So just ask if there is 3 or 7 legs on them.

GBP5 for a 3-legged J109 is a bit overpriced ?

Tanks for reply
Things start to make much more sense now?

Hi there
I said they where going to be under 5

Once I got them it will depends on how far down that will go.

Hope they are not the J109 see abowe
You have first refusal.

I am waiting for supliers to confirm that they are 2SJ109
That what I have asked for if they send me samples even better

If they have 3 legs, they're too expensive.
If they have 7 legs, they're bargains!
