The TaNFilm® PFC chip resistor series provides the high
temperature and ultra stable performance of our Tantalum
Nitride Resistive Film System in 1206, 0805 and 0603 sizes.
The unique characteristics of the passivated Tantalum Nitride
film insure long term life stability and superior moisture
performance.
Specially selected materials and processes insure initial
precision is maintained in the harshest surface mount
soldering environment. Solder coated wrap-around
terminations with leach-resistant nickel barriers insure high
integrity solder connections. A MIL-PRF-55342 qualified
version of this product is also available.
