As we discussed earlier capacitors and coils resist the flow
... As we discussed earlier capacitors and coils resist the flow of current through them. As has been noted their resistance to current flow is called reactance. When these two reactance’s are combined the combined reactance is referred to as impedance. Notice we said combined rather than added. We will ...

Surface-mount technology
Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device (SMD). In the industry it has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board. Both technologies can be used on the same board for components not suited to surface mounting such as large transformers and heat-sinked power semiconductors.An SMT component is usually smaller than its through-hole counterpart because it has either smaller leads or no leads at all. It may have short pins or leads of various styles, flat contacts, a matrix of solder balls (BGAs), or terminations on the body of the component.
