Superior anti-sulfuration characteristics
The TaNFilm
®
PFC chip resistor series provides the high precision and ultra stable performance of our
Tantalum Nitride resistive film system in 0402, 0603, 0805 and 1206 sizes. The unique characteristics of the
passivated Tantalum Nitride film ensure long term life stability and reliability in most environments.
Qualified for resistance to sulfur bearing gases, the PFC series is an excellent solution for automotive and
heavy equipment applications where precision, exceptional reliability with anti-sulfuration characteristics
is imperative.

Environmental Data
Using the same manufacturing line as the PFC Military Series, these precision chips maintain the same
superior environmental performance. Specially selected materials and processes ensure initial precision is
maintained in the harshest surface mount soldering environment. Wrap-around terminations with leach-resistant
nickel barriers ensure high integrity solder connections.
