Mahendra,
Speaking of the "Mica days," I'd like to make a slight correction to the
article. The Mica resistive material is still in production and has
become the industry standard for thin-film embedded resistors. It has
been marketed under the trade name of OhmegaPly® since 1983 when Ohmega
Technologies, Inc became a separate company.
Best regards,
Daniel Brandler
