A “Game Changer” Rectangular Aluminum Electrolytic Capacitor, Called Cubisic SLP

Cubisic SLP is the new rectangular aluminum electrolytic capacitor from EXXELIA, a world leader in manufacturing and designing capacitors. Their products are known for their high performance and reliability, which has made them the choice of many of the world's leading avionics engineering companies. However, they were looking for a new, more reliable capacitor that could withstand even greater vibration and altitude than any previous capacitor. They needed a stronger, more reliable product with a life expectancy that matched the customers' projects. Product description : Cubisic SLP is among the industry's first aluminum electrolytic capacitors designed with flat technology. The result is a lighter, smaller rectangular shape with increased surface area, which improves its capacity. As a result, it can accommodate more energy at almost any altitude or vibration level.    This makes Cubisic SLP ideal for applications where added durability is required, such as cockpits and power generation functions on aircrafts, along with being well-suited for radars and laser systems in up to 50G vibration conditions and 92K feet altitude resistance. ✅ Low profile printed circuit mounting ✅ Possible mounting with 45 x 12 bracket (A691057) ✅ Possible thermal dissipation per conduction through a lower and upper surface ✅ Switch mode power supplies, impulse current ✅ Withstands more than 92,000 feet altitude ✅ Sleeve optional Cubisic SLP comes in three sizes, is made with high-quality aluminum foil and impregnate with electrolyte. It has 2 terminals: anode, cathode. What makes Cubisic SLP so different? An example of one of the advantages of this technology is that designing a capacitor with a traditional cylindrical shape, means that 2/3 of its volume is empty, compared to this new flat design. As a result, more capacitors are packed into the same volume, thus increasing the density. What’s a Rectangular Aluminum electrolytic capacitor, and why is that important? What’s, a Rectangular Aluminum electrolytic capacitor : In short (no pun intended), a rectangular electrolytic capacitor is one of those components that keeps your electronics running safely, your ship floating, and your aircraft operating properly.  A Rectangular electrolytic capacitor is a component that essentially stores electrical energy in the form of an ‘electrolyte’. It’s made up of three layers: two aluminum sheets separated by an electrolyte solution and encased in a steel or porcelain container. And as the name implies, it’s shaped like a rectangle. It's widely used in different industries because of its reliable and cost-effective protection, which makes it the go-to component for many commercial, industrial, and aerospace uses. Rectangular aluminum electrolytic capacitors are mostly used in military aircrafts, missiles, and nautical transportation, as well as space navigation systems. In these applications, reliability is crucial for the safety of millions of people, so it is essential to choose a reliable product that offers high performance and quality. So if you find yourself with any of those use cases and/or engineering projects on your hands that require high performance and quality under extreme environments, look no further than this capacitor! Why is that important? As an example, when a military fighter jet accelerates, it can experience up to three times the force of gravity. While this is an impressive feat, consider what it does to the components in the vehicle. One such component is a capacitor. While it might seem like just a small piece of circuitry, capacitors are responsible for a variety of functions in your fighter jet, including: > Powering the radar antenna > Controlling engine performance > Controlling flight-related functions like fuel injection and landing gear operation This is because of the way they deal with heat buildup, which is an issue with capacitors in high-performance vehicles, especially on aircrafts where rapid acceleration can cause significant damage to any component. That's helpful in the cockpit, where the controls are exposed to this kind of force; a control that has to withstand up to three times the force of gravity will last longer than one that isn't designed for this. In other places on a military jet—such as power generation functions—the same principle applies: if something is going to be exposed to extreme forces (like vibration or acceleration), it needs to be strong enough not to break easily. That's why these capacitors are a great choice: they can handle extreme conditions without losing their effectiveness over time. That's why Exxelia takes the time to test every single capacitor we sell to our customers. How does its ability to withstand varying vibration levels and altitudes make a difference to the aerospace industry? What makes a rectangular aluminum electrolytic capacitor so effective for aerospace companies? The answer: They're made from high-quality material—pure and simple. But the difference between standard capacitors and those for the aerospace industry goes far beyond that. For the aerospace industry, the ideal capacitor would endure extreme temperatures, have a wide range of voltage tolerances, and withstand varying vibration levels, all while maintaining its effectiveness at an altitude of 19,000 meters—which is where Cubisic SLP comes in. As an electrolytic capacitor with an expanded operating temperature range and a very high resistance against vibration and altitude changes, this product has been able to make a huge difference in how well aircrafts can stay in control. Not only does it help prevent power outages, but also it helps avionics to stay functional when they are subjected to drastically changing conditions. Cubisic SLP capacitors are designed to handle extreme environments, which makes them incredibly versatile—and incredibly useful. From aeronautics to medicine, these capacitors can help your projects meet just about any challenges. Where can I find out more about EXXELIA’s Cubisic SLP range?

Exxelia Ohmcraft Custom Resistors Enable Rapid COVID-19 Testing

Diagnostic medical device companies have been working tirelessly to develop testing solutions, particularly those that can provide rapid and reliable results. To make these test kits possible, manufacturers turned to Exxelia Ohmcraft—a leader in thick-film, high-voltage, high-precision resistor design and manufacturing The new all-inclusive rapid testing solutions involve processing patient samples using a thermocycler, an instrument that is used to amplify DNA and RNA to identify COVID-19. The thermocyclers utilize high-ohmic-value, low-noise surface mount resistors from Exxelia Ohmcraft to function. The resistors were required to meet tight specifications, including a small form factor to enable the testing devices to be portable. “Due to the current crisis, the customer was moving extremely quickly to get these test kits developed, produced, and into the hands of as many healthcare systems as possible. As a U.S. manufacturer with industry-leading lead times, Exxelia Ohmcraft was able to provide custom resistors essential to their mission,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “We are proud to partner with companies committed to helping fight COVID-19.” Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.
