A variable resistor is a resistor with a resistance value that can be adjusted. Essentially, variable resistors are electromechanical transducers that normally work by sliding a contact over a resistive element. When a variable resistor is used as a potential divider by using three terminals, it is called a potentiometer. When only two terminals are used, it is known as a rheostat and functions as a variable resistance. There are also electronically controlled variable resistors, which can be controlled electronically instead of by mechanical action. In these cases, the resistor is called a digital potentiometer. In this blog, we will discuss potentiometers, rheostats, digital potentiometers, and their functions.

Although integrated circuits (IC) sit atop the world of electronics, the transistors within them do the bulk of the work. Within each IC are millions of transistors constantly switching on and off to allow the IC to complete its functions. Even if just one of the many transistors were to stop working, the IC could lose some or all of its capabilities.

Sensors are among the most critical parts of many devices and systems. When it comes to analyzing physical or environmental conditions, temperature is among the most important parameters. As such, when designing an electronic device or system that requires temperature measurement, designers have many options to select from. Two of the most common temperature-sensing technologies, which offer features and functionality for a wide range of uses, are negative temperature coefficient (NTC) thermistors, and resistance temperature detectors (RTD).

When managing an electrical circuit, resistors are components that serve to reduce current flow and adjust signal levels in order to further the safe and efficient distribution of power. Depending on the application that needs a resistor and its presented electrical ratings, a variety of resistor types and materials may be used in order to achieve varying operations and resistances. As one of the primary materials for manufacturing, carbon can allow for a number of robust resistors to efficiently manage the current loads of many different electrical systems.

On December 3rd, researchers from Intel Corporation and UC Berkeley published a paper in the popular science journal Nature, proposing an idea for a new kind of memory and logic circuit which could be 10 to 100 times more energy-efficient than current microprocessors. The microprocessors we have today are based off complementary metal-oxide-semiconductors (CMOS). These new devices are magneto-electric spin-orbit (MESO) and feature five times more logic operations than their older counterparts.

RF cable company, Huber+ Suhner have released a new addition to their halogen free cable family for a more ecofriendly presence. Being an addition to an already existing halogen free family series the new Enviroflex cable is most cost efficient and less costly to procure. The reason for the production of the Enviroflex family is to be able to switch any cable that may be RG compatible, typically made of fluorine/ PVC, to be able to switch over to a halogen free one. This halogen free connector will still allow for other existing connectors to be used at the simultaneously.
