Electrical Data
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, 1206, 1505, 2010 and 2512 sizes. The unique
characteristics of the passivated Tantalum Nitride film insure long term life stability and stability in most envi-
ronments.
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.
