Resistors are common electronic components that are implemented in countless devices and systems, used for establishing electrical resistance within a circuit. Depending upon their type of resistor and application, such components may serve to reduce current flow, manage signal levels, bias active elements, divide voltages, and much more. Carbon composition resistors in particular are a common fixed resistor type, serving various devices and assemblies since the early 20th century. In this blog, we will discuss carbon composition resistors, ensuring that you have a well-developed understanding of their construction, functionalities, and applications.
An integrated circuit (IC) refers to an assembly of electronic circuits that are placed onto a single flat piece of semiconductor material. Commonly comprising a vast number of MOSFETs that are placed on a small chip, integrated circuits allow for more compact and less expensive electronics that operate with higher speeds as compared to similar devices that rely on discrete components. Coupled with reliable mass production capabilities for such devices, integrated circuits serve as a common building block for countless electronic equipment types, revolutionizing the world of electronics.
Electronic devices have consistently advanced over the years with new capabilities and increased efficiency, all made possible through the various electrical components that make them up. There are numerous electrical components that serve as basic building blocks for circuits, and each has different functionalities that come together to make the device’s operations possible. Whether the electronic is a simple calculator or an advanced personal computer system, many devices will share much of the same components for their electrical circuits. In this blog, we will provide a brief overview of the most common electrical components that are found in various electronics and projects.
An opto-isolator is an electrical component that may also be referred to as an otpo-coupler or photocoupler. Regardless of name, such components are used to transfer electrical signals between two isolated circuits with light as the medium. As semiconductor devices, the transfer of signals is achieved through the use of a short optical path or link that is electrically isolated. Photocouplers or opto-couplers regularly come in the form of a single package, and they are no larger than a standard integrated circuit. As a common component for numerous circuits that may assist solid state relays, optical encoders, and other electronic components, understanding the functionality and use of opto-isolators, opto-couplers, and photocouplers can be beneficial.
From the LED lights that provide visibility to those that are used for television screens and signs, such electronic parts can cater to many applications that we regularly use or rely on in daily life. While small in size, a single LED can produce a large amount of light with great efficiency. As LEDs can come in a variety of forms to accommodate different requirements and applications, understanding the differences between certain LED light types can be useful when searching for lighting solutions.
RF Connectors (Radio Frequency), also known as coax connectors, are used to transmit radio frequency signals by connecting transmission lines to various applications. RF connectors are primarily used with coaxial cables in devices such as television receivers, two-way radios, antenna WiFi devices, and various industrial & scientific measuring devices. In this blog, we will take a look at the most common types of RF connectors: BNC, SMA, SMB, N-type, and TNC.
For electronics to carry out the various procedures that they are intended to be capable of, they often rely on a number of electromechanical components to govern voltages and resistance. With components known as resistors, a circuit may have its current flow reduced, signal levels adjusted, voltages divided, transmission lines terminated, and more. When there is a need for varying voltage values and resistances, components known as variable resistors and potentiometers are used.
A thermistor, whose name comes from ‘thermal’ and ‘resistor,’ is a type of resistor whose resistance depends on temperature. For all intents and purposes, a thermistor is a resistance thermometer. They are made from metallic oxide formed into a bead, disk, or cylindrical shape enclosed in epoxy or glass. While they do not work well at extreme temperatures, thermistors are ideal for measuring temperatures at a certain point and are most precise when used within a limited range. The range in which a thermistor will work is dependent on the base resistance.
A potentiometer, sometimes called a pot or potmeter, is a three-terminal variable resistor wherein the resistance is manually varied to control the flow of electrical current. In essence, a potentiometer acts as an adjustable voltage divider. They are considered a passive electronic component and operate by altering the position of a sliding contact across a uniform resistance. In a potentiometer, the entire input voltage is applied across the entire length of the resistor, and the output voltage is determined by voltage drop between the fixed and sliding contacts.
From simple calculators to complex computer systems, we often rely on a great number of electronic systems to carry out our daily activities. Despite this, many may not realize the large number of parts and components that come together to make up the devices that we use. As one of the building blocks of electronics, integrated circuits are a component that may be found in almost every single piece of electronic equipment, vastly changing our capabilities of manufacturing such devices. In this blog, we will discuss in detail what integrated circuits are, how they function, and the various types that are used within electronics.
