Some Electronic Components Explained For Layman – Part I

Information is now easy to find on internet, but can we find the information related to a definite subject just at one place? I don't think so. I happened to find it really difficult to make out the uses and meanings of the electronic components being used in the electronic industry. So I thought to use this platform to share some basic information about some of the components about which I can provide you some information.

Wikipedia and other encyclopedias might give you some idea about what an electronic component is; just in case you are feeling lazy enough to visit them, let me explain that you. Wikipedia explains electronic components in this manner:

'An electronic component is a basic electronic element usually packaged in a discrete form with two or more connecting leads or metallic pads.' Some common example of electronic components, which I hope you would have heard, are- diodes, integrated circuits, crystals, transistors etc. Now what do they exactly mean to you? If you think I am going to ask you questions, then you are wrong. After all why would you read my article to get bombarded with questions? I am here to answer your queries. So below are the small information about some electronic components.

Sensors: A sensor is a device which measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. Sensors are used in everyday objects such as touch-sensitive elevator buttons and lamps which dim or brighten by touching the base.

Crystal oscillator: A crystal oscillator is an electronic circuit to facilitate the mechanical resonance of a vibrating crystal of piezoelectric material to generate an electrical signal with a very specific frequency. This frequency is normally used to track of time, to supply a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters.

Digital potentiometers: A digital potentiometer adjusts and trims electronic circuits similar to variable resistors, rheostats and mechanical potentiometers and hence is sometimes called digital POT, RDAC, or digipot. These compact devices can be used to calibrate system tolerances or dynamically control system parameters.

Linear regulator: A linear regulator is an operational amplifier and a pass transistor and provides many imaginative design keys for challenging requirements.

Flash memory: A flash memory generally includes various types of delay circuits necessary for operations, a write/erase high-voltage stabilization circuit, and a reference voltage generation circuit as well as memory cells in a chip. The programming of data in flash memory is realized by the injection of hot electrons.

NVRAM: Non-volatile random access memory (NVRAM) is the general name used to describe any type of random access memory which does not lose its information when power is turned off. This is in contrast to the most common forms of random access memory today, DRAM and SRAM, which both require continual power in order to maintain their data.

Electrolytic capacitor: An electrolytic capacitor is a type of capacitor typically with a larger capacitance per unit volume than other types, making them valuable in relatively high-current and low-frequency electrical circuits.

Film capacitors: they are designed using a number of different dielectrics. Dielectrics are the insulating materials between the plates of the film capacitor.

RF connector: is an electrical connector designed to work at radio frequencies in the multi-megahertz range. RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers.

Universal Serial Bus (USB): is a serial bus standard to interface devices. USB was designed to allow many peripherals to be connected using a single standardized interface socket and to improve the plug-and-play capabilities by allowing devices to be connected and disconnected without rebooting the computer (hot swapping). They can be used to connect one USB product with another or to connect other peripherals with USB port types.

Voltage detectors: are the ICs that keep a watch over the input voltage and the moment the voltage drops below the set value it raises an alarm.

Voltage regulator: is an electrical regulator designed to automatically maintain a constant voltage level. It may use an electromechanical mechanism, or passive or active electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages.

DC to DC converter: is a circuit which converts a source of direct current (DC) from one voltage level to another. It is a class of power converter.

Charge pumps ICs: or switched-capacitor ICs provide DC to DC voltage conversion using a switch network to charge and discharge one or more capacitors. The switch network toggles between charge and discharge states of the capacitors.

Temperature sensors: are device that ascertain temperature by physical characteristics like electric resistance, EMF i.e. Electromagnetic field or thermal radiations.

Metal-oxide semiconductor field-effect transistors (MOSFETs): are electronic devices with a built-in capacitor as the input and a conducting channel as the output. An electrode called a gate controls the width of the channel and determines how well the MOSFET conducts.

Well for the time being digest the uses and meanings of these electronic components, I will explain some more in the next article.
