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.
Film capacitor series keeps its cool even at 150°C
The Exxelia Dearborn 880P series of metalised Polyphenylene Sulfide (PPS) Film Capacitors is designed to keep cool when things get hot. With an operating temperature range of -55 to +150°C, they experience no derating for DC operations and none in AC operations up to +125°C. This enables them to function at full capacity in extreme heat applications. The ability to operate at such high temperatures can eliminate the need for a cooling system within the design, thus reducing overall design time, weight and space. PPS is a high-temperature, low-loss dielectric film used in the 880P series of wrap-and-fill capacitors. This allows them to feature superior electrical characteristics over an extremely wide temperature range and maintain excellent capacitance stability in one rugged, lightweight package. It performs consistently well in commercial applications such as in power supplies and in more demanding applications, such as in avionics, on a congested control or instrumentation panel. The series features a capacitance range of 0.0047 to 10.0µF and voltage ratings from 50 to 400VDC with precision tolerances as low as ±¼% through ±10% yielding greater accuracy of capacitance. It is also a customisable unit with voltage maximums of 700 – 800VDC at 125°C maximum (higher voltages are available at reduced capacitance). Made in the USA, the units are highly durable and capable of withstanding a five-pound pull force on lead axis. They are non-polar and demonstrate low loss factor, good voltage breakdown strength and high insulation resistance (low leak current) – and are completely stable over normal temperatures, voltages and frequency ranges. These characteristics allow the 880P series capacitors to deliver high performance in a variety of applications such as DC timing circuits, low- to high-frequency AC applications, and pulse or energy discharge uses. Additionally, the package has axial leads with moisture-resistant, flame-retardant epoxy end seals and an outer tape covering for maximum performance.
