Subject: [SI-LIST] : Stub Capacitance calculation
Importance: High

Hi All,
     How can I calculate the Capacitance of a Microstrip trace Stub
with the trace routed in the component or top layer with a di-electric
thickness of 3 mils under the trace.The di-electric constant is Er=4.0.
and copper is 0.5 oz Can you give me the formula used for that? I am
looking for the answer in pF/inch.

Regards,
Prasanna
