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.
