Gold Flash Terminated Capacitor Series

Knowles NOVACAP features their gold-plated terminations for conductive epoxy or gold/indium solder attachment

Image of Knowles NOVACAP Gold Flash Terminated Capacitor SeriesKnowles specialist MLC brand, Novacap, has expanded its termination offerings to now include gold-plated terminations. Conventional termination is normally tin and lead, but lead has been banned by the RoHS directive. However, pure tin-plated terminations allow tin whiskers to grow from surfaces and can cause electrical short-circuits and failures. To help eliminate this problem of tin ‘whiskering,’ Novacap has developed a gold flash termination for conductive epoxy or gold and indium solder attachment.

Tin whiskers are microscopic single-crystal metal fibers, thinner than a human hair, capable of bridging great distances between leads on electronic components and creating short-circuits and failures. They are caused by deposit stress, such as heat, to pure tin-plated components and are almost invisible to the eye, needing magnification and special lighting to be seen. However, failures that they can cause represent a clear and present danger especially to Hi-Rel applications, such as medical implantable devices and military equipment.

NOVACAP’s gold termination consists of a 5 micro-inch minimum gold flash over a nickel barrier and is defined by the use of a “NG” in the part number ordering code. It can be specified for both their PME and High Capacitance BME product lines. To further strengthen the company’s’ commitment to alternate termination offerings other “hard to find” terminations, such as tin and lead (desired for many military applications) can still be specified.
