Have in an about ” of capacitance of “ filter wave implied meaning that understands before involve, plug-in unit capacitance, because cite crural reason, can produce parasitism inductance. The down-lead of capacitance is so shorter, parasitism inductance is smaller, so because did not cite a base,stick a capacitance, can of utmost reduce parasitism inductance.

 

It is actually when circuit board layout, if can be in ably,stick a capacitance all round had increased opening, parasitism inductance also is reduced on can older rate right now.

 

If the graph is shown 1 times, capacitance of distance crossing aperture makes an appointment with 1.25mm, right now the parasitism inductance value of capacitance is 2.1nH~2.8nH about between. Among them, wiring is wider, parasitism inductance value is less.

 

 

If the graph is shown 2 times, right now the parasitism inductance value of capacitance is 1nH left and right sides about.

 

If the graph is shown 3 times, right now the parasitism inductance value of capacitance is 0.5nH~0.7nH about between.

 

If the graph is shown 4 times, right now the parasitism inductance value of capacitance is 0.4nH~0.5nH about between.

 

If the graph is shown 5 times, right now the parasitism inductance of capacitance is worth under 0.4nH.
