6.9 ELECTRONICS AND ELECTRONIC COMPONENTS

This section will detail the principles of electronic components, electronic design procedures, and practical electronic circuits and their construction, as applicable to consumer and industrial products.

Some of the electronic components such as resistors, capacitors, and inductors are described in the preceding sections of this chapter. The following sections will detail transistors, integrated circuits, and other specialized electronic devices and formulas (e.g., for coils as shown in Figs. 6.91 to 6.93) commonly used in electromechanical design practice.

Figure 6.91: Single-layer coil.

Figure 6.92: Multilayer coil.

Figure 6.93: Spiral coil.

Figure 6.94 shows an array of modern electronic components including resistors, capacitors, diodes, trim pots, miniature relays, and integrated circuit packages, mounted on a bread-board.

Figure 6.95 shows some of the available linear and digital integrated circuits. Note that some of the devices must be mounted on a conductive sponge material before using them. These are complementary metal oxide substrate (CMOS) integrated circuits and should be handled with care to prevent a static electric charge from entering the pins of the devices. A static charge will quickly destroy a CMOS device because of its extremely high input impedance. Note that the components are surface-mounted types.
