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.
