Wrap-around terminations
(3 faces)
Construction
A thin-film material is selectively deposited on a 96% alumina substrate together with metallic contacts at each end of the resistor.
The unadjusted resistors are heat treated to give the required TCR and stability, then a precisely controlled laser trim process adjusts
the resistance value. Epoxy protection is applied and wrap-around terminations are added and plated with Nickel then Tin. Each
resistor is measured immediately before packing into tape.
Terminations
The chips are supplied with 100% Sn matte plated wrap-around terminations suitable for soldering.
