Aluminum electrolytic capacitors use an electrolytic process to form the dielectric. Wet electrolytic capacitors have a moist electrolyte. Dry or solid electrolytic capacitors do not.
|
|
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.
|
|
Compact disk-read only memory (CD-ROM) refers to a 4.75-inch, laser encoded, optical memory storage medium. Technologies include CD-ROM XA (extended architecture), CD-RW (rewritable), and CD-WO (write once).
|
|
Ceramic capacitors have a dielectric made of ceramic materials.
|
|
Chip capacitors or surface mount capacitors do not have leads.
|
|
Chip inductors are manufactured using semiconductor material.
|
|
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 cards and modules are computer boards that contain the central processing unit (CPU) of a computer.
|
|
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.
|
|
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.
|
|
Electrically erasable programmable read-only memory (EEPROM) chips are similar to PROM devices, but require only electricity to be erased.
|
|
Engineering consulting firms provide engineering services and expertise to companies in need of a specialized skill-set. Professionals in this category work with clients to define solutions to problems or to help determine and recommend the best course of action for a given initiative.
|
|
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.
|
|
Inductors coils and chokes are passive components that are designed to resist changes in current and store energy in the form of a magnetic field.
|
|
Industrial keyboards are peripheral hardware devices that include alphanumeric keys, electromechanical buttons, or sensors that users press to interface with a computer.
|
|
Information technology (IT) consulting services help design, develop and maintain the hardware and software components of computer systems.
|
|
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.
|
|
Memory modules are computer chips used to add memory to a computer.
|
|
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.
|
|
Microprocessor chips (MPU) are silicon devices that serve as the central processing unit (CPU) in computers. They contain thousands of electronic components and use a collection of machine instructions to perform mathematical operations and move data from one memory location to another.
|
|
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.
|
|
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 and potentiometers are passive electronic components that oppose the flow of either alternating current (AC) or direct current (DC).
|
|
Transistors are electronic devices made of semiconductor material that amplify a signal or open or close a circuit.
