Optocouplers, also known as photocouplers or optoisolators, are semiconductor devices that use a short optical patch or link to couple a signal from one electrical circuit to another while simultaneously providing electrical isolation. Photocouplers are typically contained in a single housing that is often similar size to an integrated circuit. Depending on the intended application, there can be a large degree of variation in size. This blog will discuss optocouplers and their function...
Resistors are a key component of electrical circuits and systems, providing resistance in order to reduce current flow, divide voltages, adjust signal levels, and more. There are also various types of resistors, each providing their own unique benefits and load capacities that cater towards different applications. Carbon composition resistors in particular are a form of fixed resistor, serving as one of the most commonly used types for a wide variety of electrical circuits. In this blog...
Thyristors, also known as silicon controlled rectifiers (SCR), are semiconductor devices that can act as electronic switches to control circuits with high voltage and current levels. Though thyristors are relatively uncommon components, they are highly useful in controlling power circuits. As such, they are ideal for many power control applications, especially in those where current and voltage levels are elevated. Despite this, thyristors can also be useful in low power applications such as light control, power supply protection, and others. Thyristors are simple parts and relatively inexpensive, making them a helpful solution for many circuits. Read more >>
Resistors are an electrical component that may be implemented within an electrical system in order to divide voltages, alter signal levels, or generally impede current flow. As a passive component, resistors are highly utilized across many electrical networks and electronic circuits, protecting many of the devices and systems that we rely on.
There are certain criteria that you should have in mind when selecting a microcontroller but before we divulge into that criteria, it’s important to understand what exactly a microcontroller's responsibility is. Microcontroller units also known as MCUs are small sized and inexpensive electronic gadgets that have played a significant role in the medical field, aerospace, technology and many more. Ultimately they serve to advance a wide range of features in other equipment, gadg...
As electronics continue to become more advanced, both decreasing in size and phasing out obsolete and unneeded parts for design, the connector remains an indispensable part of system design. For electronic circuits to function, they require connection to various power sources, inputs, outputs, and other external components. Connectors provide for this attachment, coming in a variety of sizes, types, and shapes in order to connect electrical conductors and produce electrical circuits. One connector type in particular, the terminal block, is one that may be found in virtually all sectors, including wiring, rack systems, and other I/O applications. Read more >>
In computing, a jumper is a pair of prongs used as electrical contact points installed within a computer motherboard or an adapter card. Jumpers are used to open, close, or bypass part of an electrical circuit, and are commonly employed as an alternative to a
Electrical resistors are a common electrical component that provide a circuit with electrical resistance. This may be in place to reduce current flow, divide voltages, adjust signal levels, terminate transmission lines, and cater to other operations. Resistors are basic components of electronic circuits, and they may be found in a multitude of electronic devices and networks. Varistors are a special type of resistor, allowing for varying resistance to serve as protective devices against excessive transient voltages. Varistors play important roles in a variety of applications to protect equipment and lines, and they have been prevalent in electronics since the early 1900’s. In this blog, we will provide a short overview on the functionality of varistors, as well as the applications that they benefit. Read more >>
Memory cards are a type of non-volatile data storage device that often utilize flash memory to store data. There are multiple types of memory cards, though one of the most common is the Secure Digital (SD) card. SD cards are designed for the use of storing data for portable devices, and their standards were set forth by the joint efforts of SanDisk, Panasonic, and Toshiba after their initial release in 1999. The standard that was established quickly was adopted by many other electronic manufacturers in the industry, and SD cards became commonplace for digital cameras, mobile phones, personal computers, and beyond. ...
When using technology that relies on the use of radio frequencies, such as AM and FM radio, it is important that they are able to function without interruption or interference. Two major inhibitors of electronics using radio frequency are electromagnetic interference (EMI) and radio-frequency interference (RFI). These two types of disturbances are problematic as they can detract from the efficiency of a circuit, or even stop it altogether. These interferences are caused by many natural phenomena and man-made sources including cell networks, solar flares, ignition systems, and more. Because of EMIs and RFIs causing errors and loss of data, it is important to have a way of combating their effect on electronic devices. Read more >>
