RE: Likewise for the K&K CCS kits

It is useful to battery bias even the depletion mode MOSFET's. 4x of the 3.3V button cells will do. The voltage across the cathode resistor is then larger and a single 1% resistor can be used instead of a pot dialed in to set it as precisely. This does require two 9V batteries to check the current set level though...:)

also, at high currents it would also be of use to use one of the 10M400( or the higher voltage units ) bits since they have a larger bias voltage, and the lower FET does better with more voltage across it. Watch the gate stopper value on them, as with more voltage across the DN3545 or DN2540 the capacitance is lower and you'll probably find the value needs to be higher.


Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
