Cable assemblies are collections of wires or cables banded into a single unit with connectors on at least one end.
|
|
Capacitors are electronic components used for storing charge and energy. In their simplest form, capacitors consist of two conducting plates separated by an insulating material called the dielectric.
|
|
Computer mice and pointing devices are used to control the screen-based movement of a cursor or icon on a visual computer. This category includes mice, trackballs, and touch pads.
|
|
Computer motherboards are printed circuit boards (PCBs) that house basic computer circuitry and vital components. They are devices into which other boards or cards are plugged.
|
|
CPU chips or central processing unit chips are used in digital computers and are the semiconductor component where most calculations take place.
|
|
CPU fans and coolers are integrated fans and heat sink assemblies packaged to provide optimum cooling performance, often for specific processors.
|
|
Crystals are naturally occurring materials that can be induced to resonate (vibrate) at an exact frequency. Quartz, a piezoelectric crystal that provides excellent mechanical and electrical stability, acquires a charge when compressed, twisted, or distorted.
|
|
Data storage systems are used to store, protect and manage computer data. Many types of disk drives and tape drives are available.
|
|
Diodes are electronic components that conduct electric current in only one direction, functioning as a one-way valve. Diodes are manufactured using semiconductor materials such as silicon, germanium or selenium and are used as voltage regulators, signal rectifiers, oscillators and signal modulators / demodulators.

Dynamic random access memory (DRAM) chips are single-transistor memory cells that use small capacitors to store each bit of memory in an addressable format that consists of rows and columns. Because capacitors are unable to hold a charge indefinitely, DRAM memory chips require a near-constant pulse of current to retain stored information.
|
|
DRAM modules are collections of dynamic random access memory (DRAM) chips assembled on circuit boards.
|
|
Electrical connectors are devices that join electrical circuits together. Male connectors plug into receptacles, jacks, and outlets. Female connectors contain sockets to receive other devices.
|
|
FLASH memory chips offer extremely fast access times, low power consumption, and relative immunity to severe shock or vibration. They do not need a constant power supply to retain their data.
|
|
Fuses protect electrical devices and components from overcurrents and short circuits that occur in improperly operating circuits.
|
|
Hard drives are integral, non-volatile, electronic data storage units inside computers. Traditionally, hard drives were hard-wired into computers. Removeable hard disks and drives are also available.
|
|
IC sockets and headers are board-mounted female connectors that serve as carriers for integrated circuit (IC) chips.
|
|
IC sockets and interconnect components interface or connect a microelectronic semiconductor chip to a board or larger scale device.
|
|
Industrial computer monitors are ruggedized for use in control room, factory floor, or process applications.
|
|
Industrial keyboards are peripheral hardware devices that include alphanumeric keys, electromechanical buttons, or sensors that users press to interface with a computer.
|
|
Memory chips are internal storage areas in computers. Although the term “memory chip” commonly refers to a computer's random access memory (RAM), this product area includes many different types of electronic data storage. Computer memory stores data electronically in cells. Without memory chips, a computer could not read programs or retain data.
|
|
Microcontrollers (MCU) are complete computer systems on a chip. They combine an arithmetic logic unit (ALU), memory, timer/counters, serial port, input/output (I/O) ports and a clock oscillator.
|
|
Network cable assemblies are used in the transmission of data across networks. Choices include Fibre Channel, FireWire or IEEE 1394, GPIB, serial, parallel, patch, SCSI, Ethernet and USB.
|
|
Network equipment is used to split, switch, boost, or direct packets of information along a network. This product area includes network hubs, switches, routers, bridges, gateways, multiplexers, transceivers and firewalls. Often, network equipment is defined by is protocol or port type (e.g., Ethernet switch, USB hub).
|
|
Network firewalls are systems that enforce access control policy between an organization's network and the Internet for security purposes.
|
|
Network modems (modulators-demodulators) are devices or programs that allow computers to transmit data over telephone lines. They convert digital computer data to analog sound waves and then demodulate the carrier signals to decode the transmitted information.
|
|
Network routers are protocol-dependent devices that connect subnetworks. They are also used to break down a large network into smaller subnetworks.
|
|
Network switches route packets between ports at the OSI layer 2, which means that (in Ethernet) the switches decide where incoming packets are transferred to, based on the NIC's 48-bit address.
|
|
Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs.
|
|
Resistor, capacitor networks (RC networks) are integrated circuits (ICs) that contain resistor-capacitor arrays in a single chip.
|
|
Resistors are electrical components that oppose the flow of either direct or alternating current. They are used to protect, operate, or control circuits.
|
|
Resistors and potentiometers are passive electronic components that oppose the flow of either alternating current (AC) or direct current (DC).
|
|
SRAM chips use static random access memory (SRAM), a type of memory that is faster, more reliable, and more expensive than DRAM. Unlike DRAM, SRAM does not need to be refreshed in order to prevent data loss; however, SRAM requires more power than DRAM.
|
|
SRAM modules are collections of static random access memory (SRAM) chips assembled on circuit boards.
|
|
Transistors are electronic devices made of semiconductor material that amplify a signal or open or close a circuit.
