Exxelia Ohmcraft Custom Resistors Enable Rapid COVID-19 Testing

ROCHESTER, N.Y., May 26, 2020 — Exxelia Ohmcraft plays a crucial role enabling rapid testing amid the global novel coronavirus (COVID-19) pandemic, as experts have said that widespread testing is critical to containing the spread of the virus and reopening cities.

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.

Revolutionary Exxelia MML™ Ultra-High Energy Density Film Capacitors

Discover the power of MML™ technology The best performing film capacitors on the market with the highest energy density ever! Exxelia&#39;s revolutionary MML™ ultra-high energy density Film Capacitors are a game changer in the industry due to their unparalleled energy density of 400 J/dm3. This allows for a significant reduction in size and weight in comparison to traditional Polypropylene or Polyester dielectrics, as well as an increased operating temperature of up to 140°C and protection against transient voltage. Not only do MML™ capacitors offer a large flexibility in design, allowing for low profile configurations, but they have also been tested in actual cases for controls and DC-Links functions in aircraft applications and have shown a reduction in size and weight of about 50% compared to other film technologies.   Furthermore, when compared to MLCCs, MML™ capacitors have demonstrated a reduction in weight of between 70% to 90%, with no capacitance derating with voltage applied and a low drift of less than 5% across the temperature range. Applications that previously required clusters of stacked MLCCs can now be replaced by a single MML™ unit of similar size, with the added reliability that film dielectric offers. The exceptional properties of Exxelia&#39;s new MML™ capacitors make them suitable for a wide range of applications including power supplies, DC-links, AC/DC/AC power converters, charge/discharge or power generation functions of commercial/military aircraft, satellite platforms and payloads, launchers, defibrillators, downhole tools and any other applications that require confined electronics. Samples are available upon request.   Features & Benefits : Miniaturization of the function : Up to 50% size reduction vs other film technologies ; matching footprint with stacked MLCC Lightweight : 50% lighter vs other film technologies ; 80 to 90% lighter than ceramic No capacitance derating in voltage, stable in temperature (<5% drift through the temperature range) Capacitance from 1μF to 1000μF  Voltages from 50V to 1000V  Operating Temperature -55 °C to +140 °C Highly customizable   Get your white paper around our MML Film Capacitor Download our white paper now on our innovative Miniature Micro-Layer™ (MML™) technology, which offers the highest capacitance per volume for film capacitors available on the market, by filling out the form below.   Chargement&hellip;
