12. An inductor is a coil of wire wrapped around a core of air, iron, or ferrite
(a compound made of iron particles mixed in a non-conducting epoxy
cement material). Inductors are not commonly found in digital systems,
but they may be used in volume in certain types of analog systems,
including RF and network interface applications.
Inductors function as filtering or choke components and are mainly used
in tuned circuits to block high-frequency AC signals. They pass DC easily,
but block AC signals. This action is the opposite of what a capacitor does.
Inductors are used to suppress or limit the flow of alternating current
without affecting the flow of direct current.
»»Inductors of various types and sizes are often used in electronic circuits.
»»Typically, any application that requires an inductor will also require
additional passive devices such as capacitors, resistors and magnetics.
»»Inductors have broad application potential. Target markets include
automotive, cellular, computer, consumer, industrial, power and
telecommunications.

13. Technology
Connectors are used to connect two or more electrical circuits and typically
feature a plastic or metal housing and metal contacts/terminals, with the
exception of fiber optics, which use fiber to transmit signals. For general
reference, interconnect products can be divided into six levels of packaging.
»»Many interconnect products conform to industry standards developed by
committees comprised of, among others, representatives from a number
of Avnet’s connector suppliers. Avnet routinely aggregates information
on products that are specifically designed to meet these standards.
»»Look for the connectivity points based on the level of packaging
(i.e., socketing a high value IC, connecting two boards, etc.).
»»In most systems, the main PCB (motherboard, backplane, etc.) will
need to connect to smaller boards, system IO, etc.
»»Avnet also stocks and distributes custom and off-the-shelf cable
assemblies from most of the connector suppliers listed on our line card.

16. Relays
continues to outpace the overall relay market. This is occurring because
today’s circuit designs require high-reliability, IO isolation, high-speed
switching, logic IC compatibility and noise filtering, all of which can not
be sustained by electromechanical relays. Electromechanical relays,
however, still lead in applications that must switch between AC and DC
and that need very high-voltage and/or high-current ratings with low, offstate leakage, all at the lowest cost.
»»Ideal for applications with power switching and signal
isolation requirements.
»»It’s important to remember that relay types are often applicationspecific (i.e., high-frequency, low-power signal, military, power,
general purpose, etc.).

of resistivity. The materials are processed and shaped into packages with
metal leads or pads connected to the ends of the material. Some form of
marking identifies the resistance and tolerance of the resistor and is then
printed on the package.
»»Resistors of various types and sizes are used in every electronic circuit
so every application will need these devices.
»»It’s important to determine application-specific requirements. Anytime
a semiconductor is used, a resistor will also be used so information is
needed to narrow product selection.
»»Typically, any application that requires a resistor will also require
additional passive devices such as capacitors, resistors and magnetics.
