Notes
(1) Use solder termination N for applications requiring wire bondable mounting, and solder terminations F or S for applications requiring solderable
mounting.
(2) While not recommended, palladium silver terminations could be used for solderable applications when using a solder alloy containing silver.
(3) Standard solder plating for the nickel barrier parts are solder terminations E or T. Hot solder dipped terminations F or S are also available.
