Capacitors are fundamental components in both analog and digital electronic circuits. These passive components play an important role in influencing the operational behavior of circuits. The characteristics of a capacitor vary mainly depending on the dielectric material used. The dielectric material determines the capacitance value, energy efficiency, and size of a capacitor. Fixed value capacitors can be broadly categorized into two: polar and non-polar capacitors. Non-polar capacitors include ceramic, film, and paper capacitors.

X-class capacitors are used across the line where failure would not lead to an electrical shock. X-class capacitors are divided into sub-classes and Y-class capacitors are used in “line-to-ground” applications where failure could lead to an electrical shock. It is also divided into sub-classes by their AC voltage and peak surge voltage ratings.

The innovative WE-AGDT is a compact transformer in an EP7 package. It features a wide input voltage range from 9 to 36 V, a high saturation current of 4.5 A, as well as very low leakage inductance, and a very low capacitance of 6.8 pF between the windings. This gives rise to high common-mode transient immunity (CMTI) of the gate driver system.
