The Ultimate Capacitors Guide: Learn How To Use Them
A 0.01 uF capacitor can be found in circuits that need higher frequencies filtered out. It is usually a ceramic capacitor, and if it is a through hole component, it will be marked as a 103 capacitor. The 0.1 uF capacitor is a common one you will see almost everywhere. Typically, it will be a ceramic capacitor and works well at decoupling DC ...

Dynamic Logic
Second, dynamic circuits depend on a capacitor for their operation. So, while the capacitor is typically the same parasitic that causes delay, it is also a functional component necessary for proper operation. The way the capacitor provides functionality is by providing a sort of memory on a high-impedance node. We will illustrate this for logic ...
A Complete Guide to Capacitors
A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. In ceramic capacitors, a relatively high capacitance is achievable in a small physical size because of its high dielectric constant. Its value ranges from picofarad to one or two microfarads, but its voltage ratings are relatively low.
