[sdiy] LM335 for tempco

[Peter Grenader]

Phil Gallo turned me on to 3300PPM 1/10w chip resistors as tempcos. You can
get Panasonics at Digikey in many different values and....they work.  Takes
a bit of getting used to if you've not dealt with leadless components
before, but the learning curve is quick.  I built my first 25 VCOs with them
while I was waiting for a lot of 1/8th watt leaded tempco's to arrive from
Japan and haven't received a single complaint about their stability.

Careful use of your super-glue tip and you can actually affix these SMT
resistors to the underbelly of your expo's with a a pin head sized drop of
glue and them solder 28 or so gauge solid core wire to them to suffice
integration to the through hole environment.

You guys should try it!
