<p>Going to start out by saying this is not as precision circuit and
if you need concise timing there might be better circuits to look
at or make Rt a fixed resistor and a good low drift trim pot. In
one of my electronic classes we were told don't use one shots
unless we had too.</p>
<p>That being said the type of capacitor will depend on the timing
needed. Long periods may require electrolytics, can't comment on
those. But for short periods I'd use C0G or NP0 5% or better
tolerance. Make sure the gate chip is one that has hysteresis too.</p>
