Superior anti-sulfuration characteristics
The IRC 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.
Using the same manufacturing line as the PFC Military Series, IRC’s precision chips maintain the same supe
rior environmental performance. Specially selected materials and processes insure initial precision is main
tained in the harshest surface mount soldering environment. Wrap-around terminations with leach-resistant
nickel barriers insure high integrity solder connections.
