[sdiy] Fairchild H11F1

[Scott Gravenhorst]

This is an optoisolator bipolar FET device that can be used
as a "remote variable resistor".

Specs:
<=100 ohms to >= 300 meg ohms
>= 99.9 % linearity (not sure what this means exactly)
<= 15 pF shunt capacitance
60 volt p-p signal capability
25 uSec turn-on and turn-off time  (toggles at 40 kHz ?)

They mentions active filter tuning as an application.

Has anyone here messed with this?  Could this be used in a
typical SVF for voltage controlling resonance (normally a
series variable resistor)?

Partminer comes up pretty much zip.  I see them at Digikey
with zero stock and no price, Jameco shows them at US$1.75
per unit in 10s, but gives no stock info.
