The key points from this lesson to remember is that manufacturers have a wide choice of construction design options to reinforce specific features of the capacitor.
For example pulse power ruggedized series may have a really different robust design compare to a consumer type. Thus it worth its premium price and purchase from established trusted manufacturer if those parameters are of key importance for the circuit design. (as someone do not believe that there is a difference and value to pay extra for just “labeled” power series or established manufacturer).
