TaNFilm® Precision
Flat Pack Networks
TaNFilm® resistor networks are designed for use in applications requiring a high degree of reliability, stability, tight
tolerance and TCR tracking, and low noise. The sputtering process for resistor formation has been perfected to allow a
continuous feed production line under high vacuum conditions, thus, insuring uniformity of properties between networks.
Laser trimming makes tight ratios easily achievable. The gold plated copper leads are solid phase welded to a large
area of gold conductor pads on the ceramic substrate assuring the most reliable termination and long term stability.
The Tantalum Nitride resistor material is passivated for environmental protection insuring excellent performance far
superior to military requirements.
Our TaNFilm® process enables us to manufacture networks containing different resistance values and still maintain tight
tolerances and tracking characteristics. The nature of our photo-etch process makes it readily adaptable to meet each
individual customer’s needs. Custom circuit designs and special mechanical confi gurations can be easily achieved
with a modest set up charge while maintaining our high standards of precision and reliability.
