Vermont Patent of the Month – May 2021

As technology advances, we also make it smaller. Think of how volumetrically large our tvs and computers used to be compared to how thin and sleek they are now. Vishay Sprague has continued this evolutionary pattern, developing tantalum capacitors with enhanced efficiency.

These improved tantalum capacitors have greater packing density and reliability leading to better electronic performance. Their manufacturing methods use conductive polymer cathodes and a redesigned package construction to allow for stacking of multiple anode capacitor elements. This structure relies on multi-array packaging configurations which reduces the resistance and inductance which, combined, lead to high-frequency performance. These capacitors are screened with an elevated temperature and preset high voltages – a more sensitive and efficient screening method. Through an enhanced manufacturing process, design, and screening procedures, Vishay Sprague has successfully created tantalum capacitors capable of performing better and packing more power in the same space.

Are you developing new technology for an existing application? Did you know your development work could be eligible for the R&D Tax Credit and you can receive up to 14% back on your expenses? Even if your development isn’t successful your work may still qualify for R&D credits (i.e. you don’t need to have a patent to qualify). To find out more, please contact a Swanson Reed R&D Specialist today or check out our free online eligibility test.
