A varistor is a passive, two-terminal semiconductor device used for eliminating the voltage spikes in AC voltage. It protects electrical and electronic devices from overvoltage transients via voltage clapping. Varistors can automatically change their resistance value with the change in voltage across them.

According to some engineers, lubricants are simple byproducts of the former Industrial Age. The lubrication of machine bearings is a long-standing practice that has seen various advancements over time such as the tweaking of chemicals, leading to modern day solutions that are commonly used to minimize friction. Still, the introduction of oil-based lubricants in the late nineteenth century accelerated today's modern lubrication methods.

Digital isolators are used in a variety of applications to isolate digital signals by use of CMOS and similar components. Used in high-speed multichannel circuits, serial interfaces, and logic analyzer applications, digital isolators play an essential role in signal transduction. In this blog, we will discuss the basics of digital isolators while describing their importance in high-caliber circuitry.

The ball bearing is a common type of hardware device found in many assemblies, serving to reduce rotational friction while bearing radial and axial loads. Ball bearing components are distinguishable from other bearings by the presence of ball elements that are placed between bearing races, and loads are transmitted through the balls. The radial ball bearing is a specific form of ball bearing, and it is widely used for its high versatility and ample ability to handle high axial and radial loads. To help you better understand the applications and advantages of radial ball bearings, we will discuss them in more detail.

Nearly every pipeline system, from the most basic residential plumbing setup to the most advanced industrial variety, all implement a network of valves. Depending on the design, these valves could regulate the flow of the media, create airtight seals, prevent backflow, and more. One such valve type commonly found in many applications is the throttle valve, which is one of the most simple and underappreciated designs. In this blog, we will discuss the mechanistic action of throttle valves, where they are found, and how to choose one based on the intended operating conditions.

Relays are a type of switching device that are often found in countless electrical assemblies, allowing for multiple circuits to be controlled with ease. Relays may come in a number of types and forms to accommodate particular applications and needs, and solid state relays (SSR) are a particular variation that utilizes semiconductors to switch high voltage circuits. Finding use for the management of AC power, motor speed control, power switching, and much more, it can be useful to have a general understanding of how such relays operate, as well as the different subtypes that are available.

Bearings are hardware components that are crucial for countless assemblies, serving to both reduce friction between moving parts and constrain motion to set movements. There are many bearing types that one may use, each differing in their characteristics and designs to benefit varying applications. Tapered roller bearings in particular are common rolling element bearings, capable of supporting axial and radial forces. Commonly found within vehicles and their wheels, such bearings are quite important. In this blog, we will discuss the design of tapered roller bearings, allowing you to better understand their use in various applications and settings.

Capacitors are a common type of electrical component that may be found in countless circuits, capable of retaining electrical energy within an electric field. As passive components that come in a wide variety of types, it is imperative that one is familiar with the particular capacitor variations that they need for a particular application. Film capacitors are one of the most common types, featuring non-polarized operations, high versatility, and low cost. In this blog, we will discuss film capacitors, their functionality, and applications, allowing you to determine whether or not they will be a good fit for your particular needs.
